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?
The amount of system memory for PCI textures only applies to cards that use the PCI bus or AGP cards running in PCI mode. You have a GTX 260, which use the PCI-E bus, so that setting doesn't apply to you. read the right-click help stuff.
