I can no longer enjoy playing BF3 because of this issue. It used to run fine and only give me the slightest bit of trouble during intense 32 on 32 **** blowin up everywhere kinda scenes on ultra. But now I will be playing just fine and completely randomly (but for always the same amount of time, like 30 seconds) the FPS will drop from 50ish to 10-20. After about 30 seconds it will jump back up to 50. It will run fine for the next 5-15 minutes then the same **** will happen. I tried to re-install the game, as well as updated video drivers.
Lastly I noticed today while investigating the problem that for some reason my 'GPU usage' goes down in accordance with the FPS drop. Is that an odd symptom? Cause it struck me as odd. See below
It says in afterburner it got up to 85*C. Which is pretty warm, but I don't think it's the GPU itself, it's the memory on the video card that is probably getting too hot, I believe anyways, if this is even the problem at all.
If you have crappy airflow in the case, try to fix that. If that's not an option, Leave the fan speed of the GPU at 90%+, take off the side panel, and put a small fan if you got one next to the case. If that solves your issues by god you've done it.
Back when I had an HD7950, I would have a similar problem if I left a youtube tab open and tried to play a game. With that said, your card also got pretty damn hot, and look at your fan RPM, it was barely getting above 45% when your card was pushing 85C. Consider setting up a custom fan profile with MSI Afterburner or EVGA Precision.
Yeah I've done some reading and mid 70's and even 80 seems to be acceptable for 570's. But yeah mine does still seem to run pretty hot. I have an antec sonata III I think it is and it does in fact have horrible airflow. I have thrown in one fan on the side and one on the front but it still results in poor airflow.
Nothing else significant running in the backround. When that screen cap was taken I had already turned AMD cool and quite off, and turned the GPU fan to 100%. I'm afraid it might be an overheating like problem but there is no more room for another fan.
Do what I said about taking off the side of the case and putting a desk fan or some other fan next to the case. See if it reoccurs so you know whether or not it's a temperature problem.
Also, you put a fan on the side of the Sonata III? Did you modify it or did you just glue the fan against the inside of the case. If it's still a solid panel like my Sonata III was, that isn't going to do anything.
