After 30 minutes of gameplay, the game slows to a crawl
That part bothers me. If the videocard was the problem, framerates would be bad all the time, not after 30 minutes of gameplay. Might want to check CPU/GPU cooling as a possible cause.
I just downloaded SiSoftware Sandra. The program indicates that the CPU temp is at a solid 39 Degrees Celsius, and the ATI Catalyst Program indicates that the GPU runs at 60 Degrees Celsius with the clocks maxed out. From what I know, they're running quite comfortably...
yeah, sounds like a cooling problem. I know when my temps start reaching 60 degrees Celsuis, lots of my games start getting a bit slow and laggy(framerate lag), but thats because i have the fan speed set too low through speedfan. Thats my fault(I set it down because my CPU fan is loud at full), and i can run pretty much any game. I've come across it in counter strike quite a few times.
Open up the case and clean it out if its somewhat dusty. That could be a problem with cooling...
Well, looks like I'm wrong there. I'll check out the innards of the PC this weekend and clean out any annoying dust that I find. I'll also inspect the fans to make sure they're running solidly (as quiet as this PC is, I really should check that out). lol
Though even if I get the Temp down, this definitely won't help the overall performance. The framerates are still fairly poor during the start of each game. The only way to acquire a smooth framerate for me is to set the graphics to low fidelity, which looks horrible, so it's definitely the card overall. I'll give both the NVidea and ATI cards a look over. Thanks guys.
