What's funny is that I dont' get any of the blur people talk about with Doom 3. Maybe it's because of mods, because for example with the Redux mod, post processing effects from sikkmod like Bloom,SSIL DOF and HDR do make the image softer if enabled. The DoF for example breaks with 8xSGSSAA and causes the DoF to have aliasing, where as 4xSGSSAA does not. But when DoF is activated the in focus areas get AA'd slightly different than without.(Slightly softer but better resolve of some specular problems). But with it tweaked right, I don't really see any evidence of significant over softening of the image with AA. Example comparison of some PP effects being enabled with 4xSGSSAA creating obvious blur http://www.screenshotcomparison.com/comparison/118914| Comparison of tweaked settings (Just DoF on Zoom and in Cutscenes along with HDR enabled) without AA and with 4xSGSSAA. There isn't any significant blurring. Text displays are obviously aliased without AA but do get some minor high frequency attenuation with AA on and no LOD adjustments. Same with other surfaces but nothing like the above comparison. http://www.screenshotcomparison.com/comparison/118915 Maybe i'll have to check Vanilla D3 again. Hard to match the shots quickly but here's Vanilla vs the mod Very slight sharpness difference (Probably due to having HDR or DoF on in the mod) http://www.screenshotcomparison.com/comparison/118916 What are you guys seeing with AA and Doom 3?
