Every PC Graphics Setting Explained: Which Ones Tank FPS and What to Turn Down First

You open a brand-new game, jump into the graphics settings, and you're staring at 25+ options with names like "volumetric fog quality," "screen-space reflections," and "anisotropic filtering." You have no idea which ones matter. So you either crank everything to Ultra and wonder why you're getting 40 FPS — or drop everything to Low and wonder why your NVIDIA RTX 5070 Ti looks like it's rendering a game from 2012.

Neither approach is right. The truth is that some graphics settings obliterate your FPS while being barely visible, and others look dramatically better while costing almost nothing. Knowing the difference is the single fastest way to improve your gaming experience without spending a dime on hardware.

TL;DR: The biggest FPS killers in modern games are ray tracing (especially RT global illumination), volumetric effects, and shadow quality. The settings you should almost never turn down are texture quality (free if you have enough VRAM), anisotropic filtering (nearly zero cost), and render distance in most engines. Below we rank every common setting by FPS impact vs. visual quality so you know exactly what to touch first.

Why Graphics Settings Matter More Than You Think

Before we dive into individual settings, here's an important concept: graphics settings determine whether your system is CPU-bottlenecked or GPU-bottlenecked.

At Low settings, your GPU finishes rendering each frame quickly and spends most of its time waiting for the CPU to prepare the next frame. Your GPU usage drops to 60–70%, and you're CPU-limited. Raising settings loads the GPU more, keeping it at 95–99% utilization — which is exactly where you want it.

The sweet spot is finding settings that keep your GPU fully loaded at your target framerate. That's why blindly dropping everything to Low can actually give you worse frame pacing than a well-tuned Medium/High mix. If you're not sure where your bottleneck sits, run your system through our free PC bottleneck analyzer — it'll tell you exactly which component is the limiting factor.

The Settings That Kill FPS (Turn These Down First)

These are the settings with the highest performance cost relative to their visual improvement. When you need more frames, start here.

1. Ray Tracing (Global Illumination, Reflections, Shadows)

FPS Impact: Extreme (30–60% loss at Ultra) Visual Impact: Noticeable but not essential

Ray tracing is the single most demanding feature in modern games. But not all RT is equal:

• RT Global Illumination — The heaviest. Calculates realistic light bouncing through entire scenes. In games like Cyberpunk 2077, Alan Wake 2, and Indiana Jones and the Great Circle, enabling RT GI can cut your framerate in half even on an NVIDIA RTX 5080. Turn this off first if you need frames.
• RT Reflections — Moderate-to-heavy cost. Provides accurate reflections on glass, water, and metallic surfaces. Screen-space reflections (SSR) are a decent substitute at a fraction of the cost.
• RT Shadows — Lighter than GI or reflections but still costly. The visual difference between RT shadows and high-quality shadow maps is subtle in most scenes.

Our recommendation: Unless you're running an RTX 5080 or better at 1080p with frames to spare, disable ray tracing entirely and enable DLSS or FSR to claw back performance. Ray tracing at 30 FPS looks worse than rasterization at 90 FPS — smooth motion always wins.

2. Volumetric Lighting / Volumetric Fog

FPS Impact: High (10–25% loss at Ultra vs. Low) Visual Impact: Moderate — gorgeous in specific scenes, invisible in others

Volumetric effects simulate how light interacts with particles in the air — god rays streaming through trees, fog rolling through a valley, dust motes in a dungeon. They look stunning in atmospheric games but require heavy compute work across the entire screen.

The trick: most games look 90% as good on Medium volumetrics as on Ultra. The Ultra setting usually just increases the resolution of the volumetric buffer, which costs a lot of GPU time for subtlety only visible in side-by-side screenshots. Drop this to Medium first.

3. Shadow Quality

FPS Impact: High (8–20% loss going from Low to Ultra) Visual Impact: Diminishing returns past High

Shadow rendering is expensive because the game essentially re-renders the scene from the perspective of every light source. Higher shadow quality means higher-resolution shadow maps, longer draw distances for shadows, and more objects casting them.

Here's the optimization play: set shadows to Medium or High, never Ultra. The jump from Medium to High gives you softer, more natural shadow edges. The jump from High to Ultra adds shadow detail you'll never notice during gameplay — longer shadow draw distance and slightly sharper penumbras that only matter in screenshots.

4. Screen-Space Ambient Occlusion (SSAO / HBAO+ / GTAO)

FPS Impact: Moderate-to-High (5–15% depending on implementation) Visual Impact: Subtle but important for depth

Ambient occlusion adds soft shadows in crevices, corners, and where objects meet surfaces. Without it, games look "flat" — like everything is floating slightly above the ground.

The different implementations ranked by cost:

• SSAO — Cheapest, slightly lower quality
• HBAO+ — NVIDIA's improved version, moderate cost, good quality
• GTAO — Common in modern engines, similar cost to HBAO+
• RTAO (Ray-Traced AO) — Expensive, only enable if you have a high-end GPU with RT headroom

Set this to Medium or HBAO+/GTAO. The visual payoff of having ambient occlusion on is huge compared to off. But Ultra-quality AO doubles the rendering cost for almost no visible difference over Medium.

5. Post-Processing Quality

FPS Impact: Moderate (5–12%) Visual Impact: Varies wildly by game

"Post-processing" is a catch-all for effects applied after the main scene is rendered — motion blur, depth of field, bloom, chromatic aberration, lens flare, and film grain. In many games, this single slider controls all of them.

Most competitive gamers disable motion blur and depth of field entirely since they obscure visual information. Dropping post-processing to Medium or Low often removes the cinematic fluff while keeping the look clean. This is one of the easiest free FPS wins in any game.

The Settings That Cost FPS but Look Great (Adjust Carefully)

These settings have a meaningful performance cost but also provide clearly visible improvements. Adjust based on how many frames you can afford to spend.

6. Anti-Aliasing Method

FPS Impact: Varies wildly (TAA ≈ 2–5%, MSAA 4x ≈ 15–30%, FXAA ≈ 1%) Visual Impact: High — jagged edges are immediately noticeable

Anti-aliasing smooths out the jagged "staircase" edges on diagonal lines and object edges. The methods ranked by quality vs. cost:

• FXAA — Nearly free, blurs the entire image slightly. Acceptable on lower-end hardware.
• TAA (Temporal Anti-Aliasing) — The industry standard. Low cost, good quality, but can cause ghosting and slight blur on some implementations. Most games default to this and it's usually the right choice.
• MSAA (Multi-Sample AA) — Old-school brute force. Looks crisp but extremely expensive in modern deferred-rendering engines. If a game offers MSAA, it's likely designed for it (like CS2) — otherwise avoid it.
• DLAA / FSR Native AA — Uses NVIDIA or AMD upscaling networks at native resolution purely for anti-aliasing. Excellent quality, moderate cost (similar to TAA). A hidden gem in games that support it.
• DLSS / FSR (Upscaling) — Renders at a lower internal resolution and reconstructs the image. Technically not AA but replaces it. At Quality mode, the visual loss is minimal and you gain 30–50% FPS. Read our full DLSS vs FSR breakdown.

Our recommendation: Use TAA or DLSS/FSR Quality. Avoid MSAA in modern titles unless you have frames to burn.

7. Draw Distance / Level of Detail (LOD)

FPS Impact: Moderate (5–15% in open-world games, negligible in linear games) Visual Impact: Very noticeable in open worlds

Draw distance controls how far away objects are rendered at full detail before being replaced with simpler models or disappearing entirely. In open-world games like The Witcher 4, GTA VI, and Starfield, this setting dramatically impacts both visuals and performance.

In linear or corridor-style games, draw distance barely matters — the game only renders what's ahead of you anyway. In massive open worlds, Ultra draw distance can tank performance because the engine is rendering thousands of objects you can barely see on the horizon.

Set this to High in open-world games, Ultra in linear games. You'll almost never notice the difference between High and Ultra draw distance during gameplay, but you'll definitely notice the 10+ FPS.

8. Water Quality / Ocean Simulation

FPS Impact: Moderate (3–10%) Visual Impact: Stunning when near water, irrelevant otherwise

Modern water rendering in games like The Witcher 4, Sea of Thieves, and Black Myth: Wukong can be breathtakingly detailed — real-time reflections, tessellated waves, foam physics, subsurface scattering. It's also surprisingly expensive.

If the game is set primarily on land, drop water quality to Medium and pocket the frames. If you're playing a game that's heavily water-focused, it's worth keeping on High.

The Settings That Are Basically Free (Never Turn These Down)

These settings cost almost nothing in performance but make a visible difference in image quality. Turning them down is leaving quality on the table for no reason.

9. Texture Quality

FPS Impact: Almost zero (0–2%) — IF you have enough VRAM Visual Impact: Massive — the single most visible quality difference

This is the most misunderstood graphics setting. Texture quality controls the resolution of the surface images applied to every object in the game. Higher textures look dramatically sharper and more detailed.

Here's the critical insight: texture quality doesn't cost GPU rendering time — it costs VRAM. Loading a 4K texture takes the same GPU rendering effort as loading a 1K texture; the difference is how much video memory it occupies. If your NVIDIA RTX 5070 has 12GB of VRAM and the game's Ultra textures fit within that, there is zero FPS penalty for using them.

Only lower texture quality if you're running out of VRAM (which causes stuttering from memory swapping). You can check this with MSI Afterburner's VRAM usage overlay. For a deeper dive, see our guide on VRAM bottlenecks.

10. Anisotropic Filtering (AF)

FPS Impact: Essentially zero (< 1% even at 16x) Visual Impact: Very noticeable on ground textures viewed at angles

Anisotropic filtering keeps textures sharp when viewed at steep angles — floor tiles, roads, grass, anything stretching away from the camera. Without it, textures turn into blurry mush within 20 feet of your character.

Always set this to 16x. The performance cost has been negligible since approximately 2010. There is no reason to run this at anything less than maximum on any GPU made in the last decade, including an AMD RX 7800 XT.

11. Texture Filtering Quality

FPS Impact: Near zero (< 1%) Visual Impact: Moderate — affects texture sharpness globally

Related to anisotropic filtering, texture filtering quality controls the method used to sample textures. Bilinear → Trilinear → Anisotropic, in order of quality and negligible cost increases. Always max this out.

12. Color Grading / Sharpening / Film Grain

FPS Impact: Zero to negligible Visual Impact: Personal preference

These are post-process effects that apply a color filter, a sharpening pass, or simulated film grain to the final image. They cost virtually nothing. Set them to whatever looks best to you — though most competitive players disable film grain and enable slight sharpening for visual clarity.

The Cheat Sheet: Settings Priority for Maximum FPS

Here's a quick-reference table for when you need to squeeze out frames fast. Start at the top and work down until you hit your target framerate:

| Priority | Setting | Set To | Typical FPS Gain | |---|---|---|---| | 1 | Ray Tracing (all types) | OFF | +30–60% | | 2 | Volumetric Lighting/Fog | Medium | +10–20% | | 3 | Shadow Quality | Medium/High | +8–15% | | 4 | Enable DLSS/FSR (Quality mode) | On | +30–50% | | 5 | Ambient Occlusion | Medium/HBAO+ | +5–10% | | 6 | Post-Processing | Medium/Low | +5–10% | | 7 | Draw Distance / LOD | High | +5–15% | | 8 | Anti-Aliasing | TAA | +0–10% | | 9 | Motion Blur | Off | +2–5% | | 10 | Water Quality | Medium | +3–8% |

Never touch (always keep maxed):

• Texture Quality (unless VRAM-limited)
• Anisotropic Filtering (16x, always)
• Texture Filtering Quality

How to Tell If Your Settings Are Actually Optimal

Tweaking settings is only half the battle. The other half is verifying that your hardware is being utilized correctly after the changes.

Here's what to check:

1. GPU usage should be 95–99% during gameplay. If it's lower, you're CPU-bottlenecked — lowering graphics settings further won't help and may actually make performance worse. Read our guide on CPU vs GPU bottlenecks for more context.

2. Frame times should be consistent. Stable 16.6ms frame times (60 FPS) feel better than frame times that spike between 8ms and 25ms (averaging 60 FPS but stuttering). Use the MSI Afterburner frame time overlay to check this.

3. VRAM usage should stay below your GPU's limit. If VRAM usage exceeds your card's capacity, you'll get periodic hitches as the game swaps textures in and out of system RAM. This is the one case where lowering texture quality helps.

4. CPU usage shouldn't be pinned at 100% on any single core. Modern games often bottleneck on a single main thread even if your CPU has 16 cores. If one core is maxed, you need a faster CPU — not lower settings. See how many CPU cores you actually need for gaming.

The fastest way to check all of this at once is to run your system through our free PC bottleneck analyzer — it scores your entire build and tells you whether you're GPU-limited (good), CPU-limited (upgrade CPU or lower specific settings), or RAM-limited (enable XMP/EXPO).

Game-Specific Optimization Tips for 2026

Different game engines handle settings differently. Here are quick-hit optimization tips for the most popular titles right now:

Unreal Engine 5 Games (The Witcher 4, Marvel Rivals, Hellblade II)

UE5's Nanite mesh system and Lumen lighting are the big performance eaters. Lumen is essentially built-in ray tracing — setting global illumination to Lumen (Software) is far cheaper than Lumen (Hardware/RT) with almost identical results. Nanite's cost scales with scene complexity, so lower draw distance helps in dense scenes. For more, see our UE5 optimization guide.

Cyberpunk 2077 / REDengine

The biggest single toggle is Path Tracing — it replaces all rasterized lighting with full RT and halves performance even on an NVIDIA RTX 5090. Use "RT Ultra" or "RT Overdrive" only if you can maintain 60+ FPS with DLSS Frame Generation. Crowd density also hits CPU hard in Night City.

CS2 / Source 2 Engine

CS2 is CPU-heavy and benefits hugely from fast RAM. Shadow quality is the biggest GPU setting to adjust. Most competitive players run Medium shadows with everything else on High/Ultra since the Source 2 engine is well-optimized. Multisampling AA (MSAA) is available here and works well — use 4x if your AMD RX 9070 XT can handle it.

Starfield / Creation Engine 2

Starfield's crowd density and shadow draw distance are the primary performance drains. Drop shadows to Medium, crowd density to Low-Medium, and enable FSR 3 or DLSS if modded. The Creation Engine has always been CPU-sensitive — if you're struggling, check out our 1080p vs 1440p vs 4K bottleneck resolution guide.

Frequently Asked Questions

Which graphics settings affect FPS the most?

Ray tracing (especially global illumination), volumetric lighting, and shadow quality are consistently the three most performance-heavy settings across modern games. Disabling ray tracing alone can improve FPS by 30–60%. After that, lowering volumetric effects and shadows to Medium typically recovers another 15–25%.

Should I just use the Low preset for maximum FPS?

No. Running all settings on Low often underloads your GPU, shifting the bottleneck to your CPU and causing worse frame pacing. The goal is to keep your GPU at 95–99% usage at your target framerate. Start with Medium or High, then selectively lower the expensive settings listed above until you hit your target.

Does texture quality affect FPS?

Not directly — texture quality costs VRAM, not rendering performance. As long as the textures fit within your GPU's video memory, Ultra textures cost the same as Low textures in terms of FPS. Only lower texture quality if you're exceeding your VRAM limit and experiencing stuttering.

What is the best anti-aliasing method for performance?

TAA (Temporal Anti-Aliasing) offers the best balance of quality and performance in most modern games, costing only 2–5% FPS. For even better results, DLSS or FSR at Quality mode provides superior anti-aliasing while actually boosting your framerate by rendering at a lower internal resolution.

How do I know if my graphics settings are causing a bottleneck?

Monitor your GPU and CPU usage during gameplay using MSI Afterburner or the in-game overlay. If your GPU is below 90% usage, your settings are too low (GPU is waiting for the CPU) — raise graphics settings or increase resolution. If your GPU is at 99% and you want more FPS, lower settings starting from the top of our priority list. For a complete system analysis, use our free bottleneck analyzer to pinpoint exactly which component is limiting your performance.

Is it better to lower resolution or lower graphics settings?

Lower individual graphics settings first — specifically ray tracing, volumetrics, and shadows. Lowering resolution affects everything on screen uniformly and makes the entire image blurrier, while targeted settings adjustments preserve overall clarity. If you still need more FPS after optimizing settings, use DLSS or FSR at Quality mode instead of dropping native resolution, since these upscalers produce a much cleaner image than raw resolution reduction.
