How to improve FPS in VRChat (PC)
VRChat is a completely atypical case for an FPS optimization site: it's not a game with levels designed by a studio, but a social platform where thousands of creators upload their own worlds and avatars with no technical performance review whatsoever. That means your framerate can go from a stable 90 FPS to 15 FPS in a matter of seconds, simply by entering a crowded room or running into the wrong avatar. Optimizing VRChat isn't just about tweaking the graphics menu — it's about understanding how the Unity engine handles (or suffers under) unoptimized user-generated content.

1. Quick wins (no visual loss)
Start here. Each one adds a little, but together they give +105% free FPS.
Avatar Performance Rank
VRChat ranks every avatar as Excellent, Good, Medium, Poor, or Very Poor based on polygon count, bones, shaders, and dynamic lights. Enabling the automatic impostor for Poor/Very Poor avatars replaces those models with a very low-cost flat silhouette.
Mirrors
Mirrors in VRChat are famous for being the engine's most expensive element: every visible mirror forces the whole scene to be rendered a second time.
Shadow Quality
Real-time dynamic shadows are costly in Unity, especially when the world has multiple poorly optimized dynamic lights set up by the creator.
Render Scale
Reducing internal render resolution below 100% directly lowers the pixel load the GPU has to process.
Frame Rate Limit
VRChat in desktop mode isn't limited by the headset's refresh rate, so leaving the framerate uncapped makes the GPU constantly work at maximum with no real benefit.
2. Medium impact settings
Here's where most of the FPS is. Minor visual impact, major performance impact.
Anti-Aliasing
Antialiasing in VRChat smooths the jagged edges typical of low-poly avatars and worlds.
Physbones / Dynamic Bones
Bone physics systems used by many avatars consume CPU proportionally to the number of nearby avatars with physbones active.
Max Avatars at Full Quality
VRChat lets you adjust how many avatars are rendered at full quality before the rest switch to a simplified version, prioritizing by distance.
Particle Quality
Many avatars and worlds use custom particle systems that may be poorly optimized by their creators.
3. Upscaling (DLSS / FSR / XeSS)
The biggest gain in the game. Compatible with almost any modern GPU.
4. Tips by GPU
NVIDIA
- •Enable low-power/performance mode in the NVIDIA control panel for VRChat, since it has very irregular load spikes.
- •If you use VR mode with a compatible headset, enable NVIDIA Reflex where available.
- •Keep drivers updated, especially after major VRChat changes (SDK3, Udon).
AMD
- •Use Radeon Chill or per-profile FPS caps to avoid the GPU running at 100% in simple "Excellent" worlds.
- •Check that Windows' graphics settings have VRChat.exe set to "High performance" if you're on a hybrid laptop.
- •On older AMD cards, keep an eye on VRAM usage.
Sistema
- •The CPU matters more than usual in VRChat: physbone physics, spatial audio, and Udon logic are single-threaded loads.
- •Install VRChat on an SSD: worlds and avatars are downloaded and cached constantly when entering new rooms.
- •Close overlay applications since they compete directly for the same CPU VRChat needs.
5. Known game issues
Unpredictable FPS drops when switching worlds or rooms
Performance in VRChat can change radically from one instant to the next without touching a single setting, simply by entering a room with a poorly optimized avatar.
Progressive memory leak in long sessions
Many users report a gradual increase in RAM and VRAM usage the longer a session runs without restarting the client.
Custom shaders with very high hidden cost
The most popular third-party avatar shaders enable very advanced visual effects, but many creators enable dozens of features simultaneously without measuring their real cost.
