GPU Usage drops resulting in low FPS
So I've had this problem for a while now were when I play BF3 after say 10 minutes my GPU usage drops low making my game have extreme lag. It also happens in other games such as Skyrim and Dead Rising 2. My computer is fine at running the games, I get about 60 - 80 FPS on Ultra while playing BF3 but I don't understand why this happens. My temperatures are fine from what I know, my GPU is on 40C and my CPU's on about 45C. I think it may be a PSU problem as from what I've heard my PSU isn't a very good make (HEC Compucase G7 Power Extreme 880W Power Supply) It may be that it's overheating and resulting in not being able to put out the wattage for my Graphics Card, if anyone knows any software where I can monitor my PSU I'll give it a shot.

This is a screen shot of my results on MSI Afterburner displaying my GPU Usage from idle to make use (Playing BF3) These 50% drops in GPU Usage cause major FPS drop dropping it down to about 20FPS.

I have the same problem with the configuration:
Mainboard: AsRock 990FX Killer
CPU: AMD FX-9370
Graphics: Asus Radeon R9 280X
PSU: Corsair 750W

...and I also tried out an NVIDIA GTX 770 - same drops.

Did anyone actually solve this by changing the motherboard?

I`ve ran into the same situation as yours


I haven't fixed it no. I recently got a new PSU and Graphics card but that didn't solve anything. But I think it's my Motherboard (MS 760GM-P21 FX) throttling the performance of my GPU and CPU.

I'm only 14, I got an old build from a friend and upgraded from there. All self taught, only got help when replacing a cpu. That PSU is equal to about 80 GBP over here. My 650 Ti was $180 AUD :( 


Aus prices are horrendous, if you're in victoria try PC case gear,. They do national shipping as well but there might be a more competitive place to buy from on a national basis that I'm unaware of.


I'm in NSW, and I like MSY, they are quite good, but usually use ebay

No problem,glad I could help, I'm from Australia. I'm not the best builder, fairly new actually. Are parts just as expensive over there?


Most can be classed as expensive for example that PSU is only like £68 or so. I'm pretty new to PC's and stuff, I'm only 16 so I get my Dad to help with a lot of the stuff to do with my computer like installing parts and so on. I unfortunately made the wrong choice by buying a custom built PC because my Dad didn't really have the knowledge to build a whole computer. Once again tho dude, thanks a lot for the help I'll be sure to try get a new power supply and see if that works :)
