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.
