Hi all, Hopefully you chaps can shed some light on my problem. I am running 2x7800GT in an SLI configuration. Stock speeds, and was running happily with one of the later 8x.xx drivers. Since upgrading to version 91.31, I have two issues: 1) I have green speckles corrupting my image quality. Where they appear depends upon what is being shown... but I generally have a scattering of them over the whole screen, and they flicker lighter and darker green at high speed! It seems to mainly affect textures - for example the entire floor in Titan Quest can become speckly (and some areas of the game are worse than others) and even just 2d items such as the "Stage Complete" message in Stepmania have the same green dots scattered around its edges. Very strange! 2) Performance seems to be more "stuttery" than before. I am talking mainly from my experience of Titan Quest after upgrading drivers - although this specific game suffers from (video) bugs anyway so the game could well have some specific issue that is not related to the drivers. However these troubles were not present with my 8x driver before. I definitely followed the "clean driver installation" procedures that you guys have on the site (safe mode / driver cleaner etc) and more than once without altering this situation. Also: I am running in SLI mode, and use the nHancer utility to maintain my program specific profiles. I generally run in "AFR2" mode for the extra performance (it made a big difference for me with my old drivers) but have disabling that to no avail. So do you guys have experience of the specific problem? I am attracted to upgrading since so many people seem to be getting performance out of them! I could revert to my old drivers but I'm going to need to upgrade at some point to stay current! Please let me know if I am doing something wrong - failing that anything to point me in the right direction would be great!
