Essential improvements

It is highly recommended to create a Windows Restore Point before applying the changes below.

Windows Memory Manager Tuning

Enabling memory compression and page combgining (Applicable only to Windows 10/11+)

Open Windows Terminal/PowerShell with admin rights Type Get-MMAgent and press Enter for displaying current parameters Copy and paste this commands in window, ignoring errors during command insertion: Enable-MMAgent -ApplicationLaunchPrefetching Enable-MMAgent -ApplicationPreLaunch Set-MMAgent -MaxOperationAPIFiles 8192 Enable-MMAgent -MemoryCompression Enable-MMAgent -OperationAPI Enable-MMAgent -PageCombining Set-Service sysmain -StartupType Automatic Start-Service sysmain Again type Get-MMAgent and press Enter Compare with the previous parameters and the current ones after changing the settings. Now the parameters should have changed, and the new values should have been applied in the manner of commands. Close Terminal/PowerShell.

Enabling the paging file
Press Win+R and type sysdm.cpl ,3 and press Enter Click on first button Settings... and open Advanced tab and press on Change... Set Checkbox on Automatically manage paging file size for all drives Press OK and close with reboot you PC.

These settings are very important for the stability and smoothness of VRChat, as it works very intensively with RAM and paging, and without the latter it will crash often.

Even despite having more RAM in your system, VRChat can access the file system very frequently. These settings will also help in case of a slow hard drive for the entire configuration as a whole.

Resizable BAR Setting

Activation of Resizable BAR (Method for nVidia GPUs official only from 30+ series)

First of all, Resizable BAR must be enabled in the BIOS and supported by the graphics card. Download Tool: Download the latest version of NVIDIA Profile Inspector from GitHub. Locate VRChat Profile: Launch the program and type VRChat into the Profiles search bar at the top. Modify ReBAR Flags: Scroll down to section 5 - Common. Change rBAR - Feature to Enabled. Change rBAR - Options to 0x00000001 (standard for most games like Battlefield V or Returnal). Change rBAR - Size Limit to 0x0000000040000000 (this sets a 1GB limit, common for stability). Save Changes: Click the Apply changes button in the top-right corner and close window.

Resizable BAR in VRChat allows your CPU to access the entire VRAM at once instead of small 256MB chunks. This is vital for VRChat because it handles massive amounts of unoptimized user content (textures and shaders). It helps reduce micro-stutters, improves 1% low FPS, and makes texture streaming much faster, leading to a smoother VR experience.

It should be noted that changes to the profile may be reset when updating or reinstalling drivers.

Activation of nVidia GSP

Enabling nVidia GSP Firmware for offloading GPU and CPU (Method for nVidia GPUs official only from 30+ series) Step 1: Open Registry Editor Press Win + R, type regedit, and hit Enter. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000 Note: Look for the one that has your GPU name in the "AdapterDesc" string inside the 0000 or other 4-digit named folder. Step 2: Create/Modify the Key Right-click in the 0000 or other 4-digit named folder. Select New -> DWORD (32-bit) Value. Name it: EnableGPUFirmware Double-click it and set the Value data to 1. Click OK. Step 3: Reboot Restart your PC to let the driver initialize the GSP offloading. Step 4: Verification Open Command Prompt (CMD) as Administrator. Run: nvidia-smi -q If you see a firmware version number, the GSP is active and handling GPU scheduling tasks.

If any side problems suddenly appear, perform a clean reinstallation of the video driver and do not use NVIDIA GSP in the future.

NVIDIA GSP improves the VRChat (and in all of system) experience by offloading GPU management tasks from the CPU to a dedicated hardware coprocessor, which is crucial since VRChat is heavily CPU-bound. This reduction in CPU overhead results in better frametime stability, fewer micro-stutters when loading unoptimized avatars, and lower system latency, leading to a smoother and more responsive feel in Virtual Reality.

Improvements with ReBAR and GSP can also be used on nVidia GeForce 16/20+ series, but for this, a modified firmware is required for ReBAR. Also, GSP activation does NOT require ReBAR to work on 16/20+ series and can be activated independently, but ReBAR is still recommended. Additionally, in combination, HAGS can be activated through Windows settings, but starting with Windows 11, they are enabled by default.

Patching NVENC session limits using NVCleanstall

By default, consumer NVIDIA GPUs have a limit on the number of simultaneous NVENC encoding sessions. This can be bypassed during the driver installation process using NVCleanstall.

First Download the latest version of NVCleanstall. Run the application and select the driver version you wish to install. On the Installation Tweaks screen (after the component selection), check the box labeled "Apply NVENC Video Encoding Session Limit Patch". Check "Rebuild Digital Signature". Since patching the driver modifies its original binary files, this option creates a new signature to ensure the driver is accepted by Windows. Important: Also check the box "Use method compatible with Easy-Anti-Cheat". This ensures that the patched driver remains compatible with Easy Anti-Cheat protected games. Click Next to let the tool modify the driver files, then proceed with the Install. Restart your computer once the installation is complete.

This will help the graphics card in stream encoding for applications such as VirtualDesktop and simultaneous playing in VRChat.
