I’ve been having odd graphics issues as of late. Here’s the rundown:
In the game Waves, enemies and your guy tend to phase in and out of (visual) existence, as well as cursor flickering. It often looks like parts of the background are drawn in the foreground.
In Lego Harry Potter, it worked fine for a while, but near the end of Diagon Alley, weird graphical glitches started occurring (such as the polygons in Harry’s hand being drawn very strangely). After restarting the game, it seems that occasionally it will have the same problem as Waves, where weird slivers of semi-transparent polygons will be drawn in the foreground.
I haven’t played other games enough recently to know for sure, but I opened up Mass Effect 2 really quick and it seemed to have no problems. I also ran a couple other 3D games for a few minutes with no issues.
This computer has never had issues with any of these games before.
Every 3-4 days or so completely bizarre artifacting will occur on my computer. Small squares will appear in random colors over the screen, and parts of the screen will be in the wrong place (think the top half of the T in The Straight Dope logo being in the middle of the screen for no reason). The odd thing here is that it seems to be deterministic. That is, if I switch tabs, it will mess up in a different way, but if I switch back to the previous tab, it will mess up in the exact same way. Same with scrolling down/up and changing application windows entirely.
Full-screen video NEVER messes up at all, but non-full screen video is subject to the same errors as the above paragraph when the artifacting occurs.
Restarting solves the artifacting problem for another 3-4 days, but the games are just as bad no matter what.
I tried reinstalling drivers, updating drivers, rolling back drivers several versions. Nothing works on the drivers front.
Temperatures are completely, 100% fine.
I’ve run some tests on my graphics card (Radeon HD 5970) with OCCT, it never finds any errors.
I can’t tell what could be causing the issue. I’m gearing up for an OS reinstall, but does this sound like the card going to anybody? I’m betting on software because it FEELS like a software issue to me (like DirectX became corrupted and the calls are wrong or something), but I’m not sure. Does anybody have any ideas?
