Hi, I'm new to these forums, and be warned, I am not very tech savvy although I do know enough to get by. I got a computer made from CyberPower a couple months ago. I thought everything was fine with it until I decided to upgrade the video card from an ATI HD 5750 to an XFX HD 6950. That's when I noticed something was wrong, when playing RIFT: Planes of Telara I would notice my FPS drop out of nowhere almost like my GPU was throttling. RIFT is relatively new and does still have optimizing to do for ATI cards but this would happen while playing Battlefield: Bad Company 2. So it can't be the game.
This is what would happen in game: my FPS would start off around 40 FPS, then a few hours in, or even a few minutes in, it would suddenly drop to around 15 FPS and would stay there for a few minutes and then all of a sudden go back up to about 30 FPS and stay there. Then this would happen again every few minutes.
My friend told me to monitor it with MSI Afterburner and I noticed that whenever my FPS would tank so would GPU usage.
At first I thought it was a GPU issue so I sent the card in to XFX for RMA. They sent me back another one with a different revision. Still this did nothing to fix my FPS issue so now I think this must have something to do with the rest of my system. All my drivers are up to date. I’m not quite sure what the problem is. My GPU isn’t overheating and I don’t believe my CPU is either.
