I just built my PC the other day and today I tried to play some BF3, which was amazing... for a short period of time... I was getting 80-90 fps didn't see it dip below 60 once, but all the sudden it dropped down to 5fps... So I think my GPU might just be idle while playing the game and I have no idea how to fix it...
I have a i5 4670K, a R9 280X and a Coolere master V650S Gold power supply powering it... (also it's a m-ITX system...) I was wondering if it might be the PSU or whatever else, but when doing the Valley benchmark it ran just fine with about 46fps at the extreme HD preset...

If you just built the system, then i suggest you check what the temps of the gpu are while playing a game.

The other Suspect as to why the frame rate will drop may also be due to the fact if using a factory stock Intel cooler, is that you have not seated the push pins of the cooler through the motherboard correctly. If the temps of the cpu are quite high even in windows desktop of the I5
Then when Gaming will push it higher, if the cpu reaches such a temp as 90c due to an incorrectly mounted cooler then the cpu will clock down in speed to about 800Mhz.
Because it is trying to cope with too much heat generated.
This will lead to a sudden drop in frame rate in a game.

You should check both the cpu and Gpu temps.
You see valley pushes...

You see valley pushes the gpu, but a game will put load on a gpu and the cpu in the system.

Overheating should not be a problem... I have a Thermaltake water 2.0 Pro cooling the cpu and when stresstesting it the CPU it was hovering around 60-70 C on all cores when running Prime95 torture test (@4.0GHz due to the Asus built in OC feature)... The GPU also runs quite cool, at stock clock it doesn't even go past 60 C with the Valley benchmark... and I played BF3 earlier this day with 80-90fps, but then all the sudden I can't get more than 5... the GPU is not getting warm the fans are not spinning up and it seems like the gpu is just idleing...
