DX CACHE ALWAYS EMPTY

[Manuel]

when i install new driver, i cant anymore delete dx cache content, because
i mess with it.
before was local-nvidia-perdriverversion-dxcache and inside all cache to delete
now i have local-nvidia-dxcache inside always empty, perdriverversion folder is missing.

i have no clue where all dxcache generating folder location is now

For me it is in users/(myname)/AppData/Local/NVIDIA.

If it's empty, make sure the cache is enabled globally with the Shader Cache Size setting in Nvidia control panel. I've never looked to see if it's possible to disable it on a per program basis, but you might check Oblivion settings in the Nvidia control panel also to be sure you didn't accidentally disable it just for this game.

After all that, deleting Game_Settings.sav in the save games folder should cause it to recompile shaders next time you start the game.

Edit: Also, for me, game started crashing when I set the shader cache larger than default size. Stopped crashing once I set it back to default. YMMV.
