# Performance
|
||
|
|
|
||
|
|
VRChat is notorius for not looking super great compared to modern 2D titles, while also being laggy. Here are some tips for getting a smoother experience.
|
||
|
|
|
||
|
|
## Recommended Settings
|
||
|
|
|
||
|
|
This gives a good baseline for anyone to start with. Feel free to tweak and experiment further.
|
||
|
|
|
||
|
|
- Anti-Aliasing: Off or 2x
|
||
|
|
- Greatly increases GPU load (even more so on NVidia)
|
||
|
|
- Try with off first, if the jagged edges bother you too much, try 2x.
|
||
|
|
- Pixel light count: Low
|
||
|
|
- Each pixel light adds significant CPU load.
|
||
|
|
- It's extemely common for new world creators to forget to bake lighting and upload a world with too many realtime lights, killing everyone's performance.
|
||
|
|
- Turning these completely off will make some worlds look incorrect (too dark).
|
||
|
|
- Shadow Quality: Low
|
||
|
|
- Peformance hit can be disproportionately high for visual benefit
|
||
|
|
- LOD Quality: Low-Medium
|
||
|
|
- Only makes a real difference in complex scenes, such as forests, cityscapes, etc.
|
||
|
|
- Adds GPU load based on how complex the scene is
|
||
|
|
- Particle Limiter: On
|
||
|
|
|
||
|
|
## CPU Bottlenecks
|
||
|
|
|
||
|
|
In VRC, it's very easy to hit a CPU bottleneck. Avatar material count, avatar mesh count, avatar animators, pixel lights, phys bones, particles all contribute to CPU load.
|
||
|
|
|
||
|
|
By far the biggest contributors are unoptimized avatars and unoptimized worlds.
|
||
|
|
|
||
|
|
### How to check if you're bottlenecked by CPU or GPU:
|
||
|
|
|
||
|
|
1. Check GPU usage in `nvtop` (any GPU) or `nvidia-smi` (NVidia-only).
|
||
|
|
- If it's not at 100%, you're likely CPU bottlenecked.
|
||
|
|
2. SteamVR: Lower the SteamVR render resolution.
|
||
|
|
- If your FPS doesn't increase, you're likely CPU bottlenecked.
|
||
|
|
|
||
|
|
### What to do when CPU bottlenecked
|
||
|
|
|
||
|
|
Here are some tips to ease VRChat's CPU hit on your system.
|
||
|
|
|
||
|
|
#### Reduce Maximum Shown Avatars
|
||
|
|
I recommend 10-15 as a base setting, likely won't be interacting with more people than that at the same time.
|
||
|
|
|
||
|
|
#### Block by default, utilize Show Avatar
|
||
|
|
|
||
|
|
1. Set up a custom Safety profile where you block Animators and Shaders for everyone (possibly even for friends).
|
||
|
|
2. Block Poorly Optimized Avatars: Very Poor
|
||
|
|
3. Manually `Show Avatar` people who you are actively interacting with.
|
||
|
|
|
||
|
|
This gives you full control on what you're seeing, and will be able to quickly identify that one person whose avatar is wrecking your FPS.
|
||
|
|
|
||
|
|
## Avatar Optimization
|
||
|
|
|
||
|
|
Are you running around in a Very Poor avatar? Consider this a read. (And also poke your friends to do the same!)
|
||
|
|
|
||
|
|
There are tools that let you do this in a few clicks, even if you are completely clueless about what to do.
