I found out that ATT was a nice tool to use for driver-level tweaks, but when I changed MipMap Detail Level to "High Performance" I found out that it limits the texture size to 64 pixels (which ruins a hi-def game), so I changed it back to "High Quality". But since now, each time windows starts, ATT changes my MipMap setting back to High Performance, which annoys me and I have to change it back each time I reboot my computer...:bang: I tried de-installing ATT but it still resets the setting, and without ATT I can't change it back...:wanker: Btw it resets other settings too but the MipMap Detail Level setting is the one that bothers me the most... Any help here? Thanks in advance.
