Right so. Recently, I noticed that while playing some games that the graphics are kind of a mess. Edgeless Safety Cube should not look like this. This actually makes skyrim unplayable. HOWEVER some games/programs seem unaffected by this: For example, while all the Source Engine games (Portal, Half-Life 2, Team Fortress 2) suffer greatly, Sonic Generations does not. Skyrim suffers, but Oblivion does not. Initial testing using a graphics benchmarking application led me to believe that DirectX 9 was the culprit: I could run the benchmark in DirectX 10, DirectX 11, or OpenGL modes with no errors, but running it in DirectX 9 mode caused the polygon malformation I was suffering. But this couldn't possibly be the cause: I can run Red Faction: Guerrilla with the "-nod3d10" option and it runs just fine in what I must assume is DirectX 9 mode. Additionally, the graphics plugins of my N64 and PS1 emulators both use Direct X 9 and the polygons of those games do not suffer for it. I suppose my question then would be: why do I encounter graphical errors only in some games, but not others? I would imagine that a hardware error would be somewhat more evenly applied (IE: affects everything), or to only affect games which are graphics-intense. And if it was a problem with DirectX 9, then why would it only affect some games and not others? Any ideas / troubleshooting options? For the record: I have made sure I had the latest Direct X, I have made sure I have the most up-to-date graphics card drivers. Understandably, I am using integrated graphics - specifically device manager lists it as an "ATI Radeon 3100" graphics device.
