The Avatar Performance Ranking System allows you to see how much a user's avatar is affecting performance via analysis of the components on that user's avatar. You can also use it on yourself to see how performant your avatar is.

This system is provided to inform users what is likely the most performance-heavy components on their avatars, and offer basic advice on what to look into when optimizing their avatar.

It is also used to drive the Minimum Displayed Performance Rank system, which is a way for users to decide what avatars they wish to show based on their Performance Rank.

Your avatar affects everyone else's framerate, so be mindful of how your choices affect other people's experiences. Otherwise, they might see you as your Fallback!

When you open your Quick Menu, you'll see icons appear on top of the nameplates of users.

The ranks are as follows:

1. Very Poor (E): Avatars with a "Very Poor" safety rank are highly unoptimized and can have a severe impact on performance. These avatars often consist of excessive polygons, large textures, and numerous dynamic components. It's advisable to exercise caution when encountering avatars with this safety rank, as they can cause significant lag and reduce overall performance for yourself and others.
   
   
2. Poor (D): Avatars with a "Poor" safety rank are still relatively unoptimized, but they have a slightly lesser impact on performance compared to "Very Poor" avatars. They may have a moderate number of polygons, high-resolution textures, or complex animations. While they are not as severe as "Very Poor" avatars, it's still recommended to be cautious when interacting with or viewing these avatars.
   
   
3. Medium (C): Avatars with a "Medium" safety rank are considered moderately optimized. They have a reasonable balance between visual quality and performance impact. These avatars typically have a moderate polygon count, lower resolution textures, and simpler animations. They are less likely to cause significant performance issues, but it's still a good practice to be mindful of the number of avatars with this safety rank present in your vicinity.
   
   
4. Good (B): Avatars with a "Good" safety rank are well-optimized and have a minimal impact on performance. They typically have a low polygon count, smaller textures, and efficient animations. These avatars are considered safe in terms of performance and are less likely to cause any significant lag or frame rate drops.
   
   
5. Excellent (A): Avatars with an "Excellent" safety rank are highly optimized and have no noticeable impact on performance. They are typically created with careful consideration for performance and efficiency. These avatars have low polygon counts, small textures, and smooth animations. Interacting with or viewing avatars with this safety rank should not cause any performance issues.

It's important to keep in mind that safety ranks are intended to guide users in making informed decisions and managing their performance within VRChat. However, safety ranks alone do not guarantee the behavior or appropriateness of avatars. Always remain vigilant and report any avatars or users that violate the VRChat community guidelines or engage in inappropriate behavior.

In VRChat, the avatar optimization settings provide options to adjust various parameters that affect the performance and visual quality of avatars. These settings allow users to customize their experience based on their hardware capabilities and personal preferences. Here are some common avatar optimization settings you may find in VRChat:

1. Block Pooly Optimized Avatars: Clicking the left or right arrow will let you choose among performance ranks. Setting it to Very Poor will permit all avatars to show, regardless of their performance rank.
   
   
2. Max Avatar Download Size: Ensure you have a stable and reliable internet connection. A poor connection can lead to lag and performance issues. If possible, use a wired Ethernet connection instead of Wi-Fi. and Lowering the Max Avatar Download Size can help with poor connection and overall performance.
   
   Avatars with a filesize exceeding the amount selected in the settings will not be downloaded until you click "Show Avatar". This value defaults to 200MB. Clicking either the *-* or *+* arrow will adjust the value by 5MB at a time.
   
   
3. Dynamic Bone Colliders: Dynamic Bones are used to simulate realistic secondary motion in avatars, such as hair, clothing, or tails. Dynamic Bone Colliders allow these dynamic elements to interact with the environment. Enabling or disabling dynamic bone colliders can affect performance and how avatars interact with objects and other avatars.

It's important to note that adjusting these settings may affect the visual quality and fidelity of avatars. Users can experiment with different settings to find a balance between performance and visual experience that suits their preferences and hardware capabilities.

In VRChat, the terms "HQ" and "LQ" refer to mirror settings related to the quality of reflections in mirrors. These settings allow users to adjust the level of detail and visual fidelity of the mirror reflections to balance performance and visual appeal.

HQ (High Quality) mirrors offer more detailed and accurate reflections. When this setting is enabled, the mirror will reflect the user's avatar and the surrounding environment with higher fidelity, including finer details and more accurate lighting. However, enabling HQ mirrors can put a greater strain on system resources, potentially impacting performance, especially in environments with multiple mirrors or complex reflections.

LQ (Low Quality) mirrors, on the other hand, provide lower-detail reflections. Enabling LQ mirrors reduces the level of detail and complexity in the mirror reflections. This setting can help improve performance by reducing the processing power required for rendering reflections. LQ mirrors may still provide a decent representation of the avatar and surroundings but with fewer details and potentially less accurate lighting.

The choice between HQ and LQ mirror settings depends on a user's hardware capabilities and personal preferences. If a user has a lower-end system or experiences performance issues in environments with mirrors, switching to LQ mirrors can help alleviate the strain on system resources. However, users with more powerful hardware may prefer the visual fidelity offered by HQ mirrors.

To adjust mirror settings in VRChat, you can usually find options related to mirror quality in the graphics or performance settings menu within the VRChat application. The exact location and naming of these settings may vary depending on the version of VRChat and the platform you're using.

It's important to note that the availability and functionality of mirror quality settings can depend on the world or room you're in. Some worlds may restrict the ability to change mirror settings, while others may have their own custom mirror options.

In VRChat, clearing the cache refers to deleting the locally stored files and data related to the game. When you play VRChat, various assets such as avatar models, textures, animations, and world data are downloaded and stored on your computer's hard drive in the cache folder.

Clearing the cache can serve a few purposes:

1. Fixing Issues: Sometimes, VRChat may encounter problems loading assets or exhibit glitches. Clearing the cache can help resolve these issues by forcing the game to redownload the necessary files.
   
   
2. Updating Content: VRChat regularly releases updates that introduce new features, avatars, worlds, and other content. Clearing the cache ensures that you have the most up-to-date versions of these assets when you launch the game.
   
   
3. Saving Disk Space: Over time, the cache folder can accumulate a significant amount of data, which may occupy valuable storage space on your computer. Clearing the cache allows you to reclaim disk space by removing outdated or unused files.

It's worth noting that clearing the cache does not affect your account, friends list, or any other personal data associated with your VRChat profile. It primarily targets the locally stored assets to refresh or update them. After clearing the cache, the game will automatically redownload the necessary files when you launch VRChat again.

If you're experiencing issues with VRChat or want to ensure you have the latest content, clearing the cache can be a helpful troubleshooting step. However, if you're uncertain or have concerns, it's recommended to consult the official VRChat documentation or seek assistance from the VRChat community.

1. Head on over to the Debug tab in the settings.
   
   
2. Click on the Clear Content Cache button highlighted in red.
   
   
3. Click on the YES button.
   
   
   
   

Please note that clearing the cache may result in longer loading times the next time you launch VRChat, as the game will need to re-download or re-generate certain files. Additionally, if you have any custom content or avatars that were stored in the cache, they will need to be re-downloaded or reloaded the next time you encounter them in the game.

Here's an example of how core parking actually works and the meaning of an index number:

Let's say we have a CPU with total of 6 cores (including logical) this will be 100% of our CPU power, where each core will represent about ~ 17% (100 / 6 = 16.6 ~17). Now for example we would like that 4 cores out of 6 to never be parked by the OS regardless of the load. In this case we set the number to 68% (17 * 4 = 68). This will tell the OS that it can only park 2 cores out of 6. For example, if we set the number to a 100% we are basically telling the OS that NONE of our CPU cores can be parked and they should function at all times with full performance (see the pictures below), and in the opposite case scenario if we set the number to 0% or close to that, OS will be able to park any number of cores (don't forget to press the "Apply" button when you are setting the number). I hope this'll help explaining how it works.

1. Right click on VRChat in library
   
2. Click on Properties
   
3. Then, Click on "Set launch options"

There are several launch options available for VRChat.
