Preventing Shader Cache from deleting

[DustyShinigami]

Is there any way to stop Nvidia Shader Cache from deleting the saved cache files itself? I find with it on the first loading screen goes by quickly, but after a while it takes ages once the cache has been cleared.

I do sometimes use CCleaner, but after testing it just, it hasn't deleted the newly created files, so it can't be that.

Actually, I've found it to be random. Some days upon a first system boot, the game will load in seconds, then during a subsequent load, it will take minutes. The next day after a cold system boot, the game will first load in minutes and a second load will be in seconds. It switches. I haven't found a rhyme or reason to this behavior yet because it seems random, even after the machine has been booted from an "off" state and I haven't played any other games that would've causes the cache to be cleared.

I've learnt that after a certain amount of space has been used up storing the cache, it clears itself automatically. I think from now on, any game that benefits the most from shader cache being on, I'll back up the stored cache and restore it if it ever gets deleted.

Do you know where it stores the cache? There doesn't seem to be a directory for it in the save game area at least.

Thankyou.

So with that location, this could be a driver decision to delete the cache or the game's decision. It could be difficult to stop it deleting it.

Yeah, I don't think there's any way to stop it; it's hard-coded to delete after a certain amount of space has been used up. That's why it's probably best to back up the stored cache for games that benefit with shader cache being on. Not all games do.

Yeh i've just been trying to look it up. The driver will start purging it when it hits 256mb. Mine is at 245mb so i guess the game will be due a slow start up soon.

I can't find any info or settings to alter the size of it. There's nothing apart from On or Off even in Nvidia Inspector

The game deletes cache every GPU Driver update, keep that in mind.

Its this.

The shader cache is populated whenever your GPU driver is updated.
This is pretty much universal for a lot of games where the game caches shaders.
