In this area there is a textures tab. Surface format settings only has selectable directx 7 and directx 8 applications. Is the newer directx version going to be added such as 9 and 10? Is it needed because my next question relates to it. Is the option (amount of system memory for PCI textures) related to games such as Call of Duty world at war? I have 6 gigs of ram and was wondering if I tell it to use a significant amount, would it improve performance?
