Transfert old nvidia driver shaders cache to new driver cache folder ?

I want to update my nvidia driver but don't want driver to recompile shaders cache in current playing games...so is it possible to copy/paste the shaders cache folder ?
I guess somebody already did try this trick before ? what happened ?

 

copy this folders
C:\Users\(username)\AppData\Local\NVIDIA
C:\Users\(username)\AppData\Roaming\NVIDIA
unistall driver with DDU
install new driver
reboot in safe mode and copy folders in same destiny
that's how i do

 

This is so useful, gonna try it next time I install drivers after using DDU.

 

OMG! so it actually works ! OMG
Thanks

 

Couldn't Wagnard include a shader backup option or an option to keep these files/folders instead of deleting them?

 

Does it? You tested it and can confirm?

 

I could foresee issues with copying shader cache over as the reason they get recompiled after a driver update is optimizations made in drivers (good example is newest release with dx12 improvements) so it could cause issues in those situations, I am not knowledgeable enough wrt shader compliations to know if this is an actual issue, just educated guesses from having been a professional programmer for a couple decades, maybe the driver will see if the shaders need to be recompiled due to changes and invalidate the existing ones if needed, not sure.

But honestly for stability sake I wouldn't do this, sucks to have to rebuild shaders and getting stutters after a driver update but it doesn't take that long till the cache is rebuilt.

 

Shader cache is purged on driver updates for a reason which is the newer driver may not actually be compatible with shaders compiled with a previous driver version.
In other words YMMV when using this trick.

 

Didn't install new driver yet, i was guessing that if it was working for GatitoMimosin...then it should work

I was thinking that too at first

 

the shaders also include both OS version and driver version matching, so there is no way to use old shaders anyway.

the claim above that this has worked, is absurd and false.

 

Won't all the transferred entries be invalidated one-by-one as the game runs with the new driver? I am not sure how detailed the cache's indexing/versioning/etc.
