| Post subject: | Odd 5970 problem |
I've had the 5970 for a while now, and have been generally very pleased. One issue puzzles me, however: Sometimes when I play older games they run at very fast fps for up to 15-20 minutes and then nosedive (I would estmate under 10 fps). The drop in fps persists even when I close and restart the game; I have to re-boot to get the fps back up to where they were before. I first noticed this issue with FEAR, and it just popped up again when I was experimenting with Tomb Raider: Underworld. Strange thing is - it's never happened with a current gen game, only with games that are a few years old. Eyefintity isn't the issue - the problem with FEAR happened before I got my extra monitors. Heat is also not the problem. Does anyone have any ideas? |

What are the temps? You say there are not a problem but don't provide figures. What are the other components in the computer? More importantly... what is the PSU you are using? What driver version are you using? |

I checked the temps right after I exited TR:UW and they were at 77 C on both GPUs. The PSU is low (a Dell 525W) and apparently not replaceable, but I haven't had any issues with it whatesoever - for ex: I played Metro 2033 with almost everything maxed at 3480x800 for at least 6 hours one night without a single hitch. I really don't believe the PSU is part of the problem. Also: Windows 7 Ultimate 6 GB ram i7 930 creative Soundblaster XFI latest drivers on GPU and sound card, all windows updates applied |

| Post subject: | I can't say for sure but |
I can't say for sure but intuitively I would say that older games may have used a way to address the video cards memory in a way that was sloppy. They might not have released the memory properly after it use so that there was less and less available for the game leading eventually to a slow down. Many programs do that, creating computer problems only solved by rebooting. In newer games they must have solved that problem. I could be wrong in the details but it seems it has something to do with bad allocation of res sources somehow. |
