When I install new drivers, I usually delete the shader cache but since installing the latest driver and enabling DLSS4 all I have is the following:

C/users/myprofile/appdata/local/nvidia/DX cache       which grows to only 4 GB

C/users/myprofile/appdata/local ow/nvidia/DX cache    which is empty

My Nvidia control panel is set to use to use an unlimited shader cache

Has the location or name of the cache changed or can anyone explain why my cache size does not grow beyond 4 GB?

Thanks

Any takers?  I'm meaning the Nvidia DX cache

I believe 4GB may be the default Shader Cache Size.  You can set it higher or lower in NVIDIA Control Panel, Manage 3D Settings.  There seem to be varying opinions about best size, I have mine at 10GB.

It is set to 10 GB in the NVC panel, which is why I can't understand why it is only growing to 4 GB.  I even reinstalled the driver yesterday, but it made no difference and I've tried setting ot to unlimited.

Just can't figure out what is going on - I may have to try uninstalling NVIDIA profile inspector next and see if something accidentally got changed there, though it is showing the same as the NVC panel.

It seems like it must be specific to my system if nobody else knows anything about it.

That practice is a waste of time if you use NV's 'clean install' option when installing a new driver as it always clears out the cache and that because entries are tied to the specific driver being installed.  Here in 2025 do you really believe NV doesn't know exactly how much cache capacity is needed to install their shaders into?

Yeah, I noticed that the DX cache had been emptied by the new driver install on this occasion.  Still not sure why the cache is not growing past 4 GB though.

Because it doesn't need to, at all?  Just a guess but seems highly likely this is very basic stuff nowadays.

I use DDU when I delete old drivers, then all Nvidia cache will be deleted as well.

Pardon my lack of knowledge, but what is DDU? I have seen this in several posts but I still have yet to figure out what the acronym stands for. Any help/clarification is appreciated.

Thanks for the responses and sorry if I have not made myself clear.  What I would like to know is whether everyone else is only building a 4 GB DX cache or is it just me (I am set to 100 GB at the moment).

I've never set nvidia cache to higher then default and to be honest never even bother with, my system is as fluid as it can be and quite stable, very happy with the results.

Unless someone else can chime in, AFAIK there is no known advantage with higher nvidia cache.
