Currently, much of VRChat's configuration data is stored in
HKEY_CURRENT_USER/SOFTWARE/VRChat/VRChat
.
I heard this behavior is what happens when using Unity's
PlayerPrefs
(https://docs.unity3d.com/2019.4/Documentation/ScriptReference/PlayerPrefs.html).
Now, taking a look at this registry listing, we can see that there is a variety of settings data.
I think these settings data should be under the AppData directory.
Also, there is an extremely critical and confusing group of registries:
FriendsPerLocation.{instance information}_{Deck Base}
.
These are generated in very large numbers, causing problems such as heavy Social menus and VRChat crashes for those with many friends. This has been found to be (temporarily) resolved by removing the FriendsPerLocation registries.
(See comments from this Canny.)
It would be helpful if you would carefully consider what data should be in the registry and stop wasting registry by PlayerPrefs.
