Just Cause 2 low gpu usage

post #1 of 3
Thread Starter 
Hello. During this year's Steam Summer Sale i bought Just Cause 2. After installing i started it. For the first 5 seconds the gpu usage is at 70-80% and the fps at 60+, but after that windows plays that bip noise and the gpu usage drops to 6-7% and the fps to 20-30 fps.
I googled my problem but i didnt find anything useful as all the questions where asked by people with old rigs from a few years back. My drivers are up to date and i tried playing the game without my gpu overclock but nothing changed. I also tried lowering the settings to the lowest and still no change.

What "bip" noise is windows playing?

If that happens right before the performance drop, look into that.

If that's not related, check your CPU usage in the Task Manager while playing the game. Run the task manager in the background while you play for a minute or so, just make sure you experience an FPS drop while playing, then tab out, and look at the performance chart. If any core is maxxed out, it could be a CPU bottleneck that requires you to overclock it more or replace it.


If it is not a CPU bottlenecking issue, then you may want to monitor your temperatures and clock speeds. Maybe something is overheating and underclocking itself? I know sometimes if I try to overclock my GPU too much and run a demanding game, it will revert itself back to half the clock speed it was shipped at and my FPS will be halved or less until I reboot.

I dont think its an overheating issue nor a bottlenecking one. My maximum temperatures are 48 degrees for the Cpu cores and 63 degrees for the Gpu. But the Gpu doesnt even come close to this temperature as the usage stays at 6-7 % after the windows 7 default beep playing.
