NVIDIA Control Panel
The NVIDIA Control Panel serves as a comprehensive software interface for users to manage and tailor settings related to their NVIDIA graphics card. Within this application, users can fine-tune display configurations, optimize 3D settings for various applications, and enhance overall system performance. It offers a centralized platform for adjusting parameters such as resolution, refresh rate, and color settings, enabling users to customize their graphics experience based on individual preferences and system requirements. In essence, the NVIDIA Control Panel functions as a tool for graphics optimization and personalization.

Please note, that this will only work on Nvidia GPU's! AMD have their own tools, Since i don't have an AMD GPU, please let me know the AMD settings, so I may add them down the line.


Step 1
Right-click on your desktop and then select “NVIDIA Control Panel”.

Step 2
Click on "Configure Surround and PhysX" category and then select your graphics card in the drop-down menu.

Step 3
Click on “Manage 3D settings” and then on “Program settings”.
Select the VRChat program. And apply the same parameters as those present on the images below. Don't forget to hit "apply".

Windows set High Priority with EAC
As you might have noticed, you can't give Priority to games that are running Easy Anti Cheat in the Task Manager. The following steps will explain how to make anything run with high Priority on your system every time u start said application!
Please make sure you only edit the registry if you know what you are doing!


Step 1
Press your Windows Button and type "regedit" and press Enter.

Step 2
Navigate to this line: "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options".

Step 3
Right click on "Image File Execution Options"> New> Key.

Step 4
Name the new Key as "VRChat.exe". MAKE SURE the key name is the same as the game executable, in our case "VRChat.exe"

Step 5
Right click on the new key "VRChat.exe">New>Key
Name the new Key "PerfOptions".

Step 6
Select "PerfOptions" then right click>New>DWORD 32bit
Name the new DWORD "CpuPriorityClass"

Step 7
Open the newly created DWORD with the name "CpuPriorityClass" set the Value data to 3 make sure hexadecimal is selected and hit OK.

Step 8
Start your game, open task manager, right click on VrChat.exe, and it should be set automatically to High.

Side Notes
*"Process.exe" is valid for any game running EAC, simply repeat the steps from 3. replacing "VRChat.exe" with "YourEACgame.exe".

The Value 3 is equal to "High" priority, if you desire to set something else, this is the table:1 Idle, 2 Normal, 3 High, 4 RealTime (n.a.), 5 Below Normal, 6 Above Normal.
IMPORTANT: 4 (RealTime) should NEVER be used as it will result into system instability.

Priority Launch Options
VRChat has Launch Options for the Performance Priorities.


Step 1
Right click VR Chat in your Steam Library and select propperties.

Step 2
Navigate to the "General" tab. There you will see a tab for launch options.

Step 3
Paste the following arguments separated by space:
"--process-priority=<ARG> --main-thread-priority=<ARG>"

Replace the <ARG> with the Priority you want to set:

- -2: Lowest priority
- -1: Below Normal priority
- 0: Normal priority
- 1: Above Normal priority
- 2: Highest priority


What theese do
"--process-priority=<ARG>" Manually sets the process priority of VRChat to the specified level.
"--main-thread-priority=<ARG>" Manually sets the priority of the main Unity thread that VRChat runs on to the specified level.

Please Note
The operating system uses the priority level of a process to decide how to schedule processor time to it relative to all of the other processes it's running.

Setting priority levels inappropriately can degrade VRChat's performance or cause your system to become unresponsive. Carefully try out these options, don't set priority levels manually unless you know what you're doing!

Hardware-accelerated GPU scheduling
Hardware accelerated GPU scheduling can improve performance and system latency in certain workloads by reducing CPU utilization (or, more specifically, by reducing the overhead of GPU scheduling).

Step 1
Right-click on your desktop and then select “Display Settings”.

Step 2
Scroll down to the Bottom and select Graphic settings and click it. (You should find this below the Multiple displays category.

Step 3
Enable the Hardware-accelerated GPU scheduling under the Graphics settings.

Step 4
Below you can find the category Graphics performance preference. Select the "VR Dashboard" and set it to "High Performance". If you cant select "VR Dashbord" you can manually add it via under -> steamVR/bin/win64/vrdahboard.exe

High-Performance Power Plan
Changing power plan may help you to optimize Windows 10 for gaming since power plans are designed to better manage battery use on portable devices. And many Windows 10 desktop users say that this solution helps them to improve game performance.

Step 1
Press Windows key and I key together to open Settings.

Step 2
In the pop-up window, choose System to continue.

Step 3
Then navigate to the Power & Sleep tab and click Additional power settings.

Step 4
In the Power Options window, check the option High Performance.

Windows Visual Effects
Many background graphics are turned on by default, which will affect the available processing power of your PC when playing games on the computer in the foreground.

Step 1
Type View advanced system settings in the search box of Windows and choose the best-matched one.

Step 2
In the pop-up window, switch to the Advanced tab.

Step 3
Then click Settings under Performance section to continue.

Step 4
In the pop-up window, in the Visual Effects tab, copy the settings from the following screenshots. Then click Apply and OK to confirm the changes.

Ingame Settings / Optimization tips
In-game settings refer to configurable options within a video game that allow players to customize various aspects such as graphics, controls, and audio to suit their preferences and system capabilities. To optimize game performance, follow the following steps.

Pro Tip: VRChat has a search feature for the Settings


Graphics
Navigate to the Settings Menu and select Graphics.
I personally recommend using the following settings due to the noticeable decline in Quality if you go any lower. Please note that if you have turned off Anti-Aliasing via the Nvidia Control Panel the setting for anti Anti-Aliasing in the VRChat settings will become redundant.

Graphics Quality: Medium

Common
I recommend having the Particle limiter on, as it saves you from malicious content and saves you performance. Depending on your PC, you may adjust the Pixel light count.
You should cap the FPS at your Headsets / Monitor's refresh rate (in my case, 120 Hz).
Please note that some people reported performance drops when having an in-game fps cap in combination with the Nvidia control panel FPS cap. I recommend just using one of the two.



Avatars
Navigate to the Settings Menu and select Avatars.

Avatar Interactions
This setting influences if your Ears / Tail / Oppai / Hair etc. can be touched by others. While this is a nice feature for cuddles and other activities, it may impact your performance on weaker PC's. Experiment with it.

Avatar Optimizations
Here you can choose to block Very Poor Avatars and set a limit for avatar download size.
I personally don't like having this on, but it's a guaranteed performance boost on weaker PC's. On a side note, this setting can be overridden by clicking show Avatar on a hidden user!

Avatar Culling
Avatar culling hides / does not load Avatars beyond the limits you set, which results in a performance gain. The settings I found most suitable for myself are listed below, feel free to adjust them to your liking.

Avatar Download Prioritization
This is quality of life, but you can set it up so the Avatars you want to see load first.


Debug

Managed Cached Data
I recommend clearing your Cache on a regular basis, which can lead to a performance gain.
Alternatively, there are external tools like VRCX[github.com], which can, among other features, clean your cache for you. Please note that VRCX is an external third party tool not related to VRChat in any way or form.


Notable Mentions#

• Group Banners can be disabled for a performance gain.
  
• Nametags can be disabled for a performance gain.
  
• The Chatbox can be disabled for a performance gain.
