I have some questions regarding the OpenGL Shader Disk Cache, but first some background: I have been using it for various games (mostly via Wine). At first I let games store everything in default location ($XDG_CACHE_HOME/.nv/GLCache). However I quickly found out that having multiple games use the …

__GL_SHADER_DISK_CACHE_SKIP_CLEANUP=1 should remove all limitations to shader cache size, and that should work on most currently released drivers. Configuration of the size of the cache will be exposed in later drivers, expect it to appear in our changelog.

With wine you get 1 directory / game as well (Prolly / wine version, I have multiple). However if you use the default location for all games, it seems to garbage collect shader caches really fast. So I’m assuming the maximum of the entire directory GLCache can be 256mb. Separating the games to thei…

I really wish I could increase the cache size somehow.

yeah i vote for a env variable to change the cache size.

The shader cache size is a (soft) maximum of 128MB. It is a good idea to use a dedicated location for each application so that heavy applications can use the entire shader cache, in fact various games on Steam are doing exactly this. There is no setting available to increase the size of the cache c…

Like said, I’m already using separate locations for each application. But that simply isn’t enough it seems. I’m already going past that 128mb for Overwatch. I’m sure others have have issues found similar problems with other games So questions: Whats a (soft) maximum? Does it mean that it can go …

I have shader cache of GTA 5 from using DXVK/wine 552MB (that was when DXVK had its own implementation of shader cache) how on earth should we fit that into the cache? please add env var to increase it

Was wondering why Overwatch with wine and dxvk went from super smooth after cacheing a lot of shaders to awful without any major changes. Makes sense if there is a max cache size that gets garbage collected. I setup a dedicated shader cache folder for Overwatch I’ll start monitoring size on each s…

I also vote for having bigger cache dirs if technically possible.

Enhancement request tracked as NVIDIA bug 2109833.

This is a high priority bug. I’d be thankful if you implement it. SCENARIOS: Quake Champions: Unplayable until shader cache is full. But since this game shaders are so big, this process is repeated every time a new level loads. In multiplayer matches, this causes desconection and game crashes. Ce…

OpenGL Shader Disk Cache: Max Size? Garbage Collection?

Hi, I agree with the general sentiment of this thread. I would greatly appreciate the ability to increase the cache size to a user defined amount. While 128MB is fine for some games, some games require more than this. Because of this, a user should be able to set the cache size to any size they want.
