Nvidia shader cache keeps duplicating shaders for the same games

[Black Dog]

Hi,
Nvidia shaders seem to be duplicating shaders every time I play a game. For instance I play a game and then look in my shader folder and there is a shader file with something like 262mb. The file corroaponds to the game I just played due to the data and time it was created. I then go back into the game and back out and I see another file exactly the same with the new time stamp on it. So basically each time I playa game it just creates a new cache. Surely this is not right. I assume it's supposed to use the cache it created in the fist instance. At this rate after a week of playing the game it will easily hit the 10gb limit. I am new to the shader cache options as I have never really used it in the passed.

Thanks.

Wasn't sure what you meant, so I googled it.

My DXCache folder (%localappdata%\NVIDIA) is 34GB!

Mine's 70GB. There's an option to cap it in the Nvidia app though if you want.

Does you folder include multiple cache files of the same game? Mine is set to 10gb at the mo and will fill up in no time.

Hi,

I know about the cap but the question is should I have multiple cache of the same game. I thought it does it once and then uses ghat cache the next time you play the game.

This is what mine looks like for today. I've been playing one game all morning, Onimusha Way of the Sword. I haven't closed it and reopened it at any point

Blimey, that's a lot. Didnt realise it caches that many files for the same game. I assume it would not repeat those files if you come out of the game and went back in? My issue it it keeps doing the same each time I play the same game.

I've just closed the game and gone back into it and no new files have been created.

I'm not sure how exactly it works, it's the first time I've even looked at the folder to be honest. If you've set a limit of 10GB I would imagine it starts overwriting old shaders to replace with new ones when it hits that limit but I'm by no means an expert on the subject.

I just manually delete the contents of this folder every month, and start again, just in case i leave shader files in it, that are no longer needed, average 30 GB+ a month.

Must start doing this.

Okay guys thanks. I'll keep an eye on it and hopefully it won't keep duplicating.

I just have a monthly google reminder set up.

Must start doing this.

Works great doing it with a PowerShell script setup to clean caches automatically, steam, windows DX, NVIDIA and whatever others. Just have it auto run silently on boot. Or link it to cache folder size.

Just had a look, mine is only 6.4Gb.

Set to unlimited as well.

Is this Nvidia only yeah? I've a 7900XT AMD card, don't think I need to be looking do I?

Wouldn't affect AMD as bad due to instant shaders - unless you play path of exile 2. patches do a number on the shaders most times, then again I'm not sure if that instant shader thing is 90 cards only.
