| Well, a few times that it didn't completely just cut out and quite with no error log, it did say "Doom 3 has encountered an Error and Must shut down", but that was like 5 out the 15 times. Those 5 times it said that, I know it was a graphics glitch because my moniter would get all constorted, and the noise in the background would loop, like if I were firing a gun at the time, it would keep sounding like I was firing it, then the moniter would get these bars across the screen and completely freeze up the system, but most of the time, like when I would go into an elevator and it would get ready to load the next level, or when I would turn a corner and there would be a 3rd person cinematic, the game would just, go black, and shut down, no questions asked.
I checked with the game, and with my system I was able to run graphics on Medium Detail, and I had no lag what-so-ever, it's just I couldn't play it for more then 5 minutes at a time, and that I had to press F5 every 30 seconds to save my progress knowing the next second it could crash.
And you know, when I played the Doom 3 demo on that comp, it did the same thing sometimes, but when I played the demo on my moms computer, a system that lags even on low settings and all special thing-a-mabobs turned off, it would never crash, but I had extreme lag...my mom's comp has a GeForce 420 64 mb card, and integrated sound etc etc, not as powerful as my other one, but it never did this....
