It’s doing it every time the game is launched, and it writes on the BL3 temp folder which is located in the C: drive.
Pretty much a silent SSD killer, since SSD lifetime is based on the amount of writes. I’m not using DX12 anymore in this game unless that gets sorted. Could create a symbolic link to another drive, but it would be even more waiting for the game to start, as it takes longer to create shaders.
Not sure if this is happening to anyone else, but I verified it on Resource Monitor while launching the game. Not sure why DX12 isn’t getting a permanent folder so it would stop caching every time. I don’t recommend anyone using DX12 until that gets sorted by GBX.
