GPU and CPU usage drop to 0 every 5 seconds while gaming

[tomdecree]

Hello everybody

first post for me 🙂. I have a problem while gaming and cannot find a solution for it, despite the dozens of posts that I have read.

While playing games (for example F1 2013, Pro Cycling Manager 2012 or Sniper - Ghost Warrior), the image isn't smooth and the image hesitates like every 5 seconds. When opening MSI Afterburner, I can see that the GPU load and CPU load (of 1 or 2 cores, not all of them) drop to 0%. Here are some images : http://imageshack.us/photo/my-images/823/43j.gif/ and http://imageshack.us/photo/my-images/849/lfli.png/.

I already did a clean install of Windows 7 64bit (only three days ago), updated everything to the latest drivers (deleted the old ones in safe mode), tried changing some ingame settings (such as lowering screen resolution, lowering quality, playing with antialiasing) but nothing worked.

This is my build :
Motherboard ASRock 960GM/U3S3,
CPU AMD FX(tm)-8150 Eight-Core Processor without OC and Cooler Master Hyper 212 EVO,
GPU Radeon HD 7750 2GB without OC,
PSU CORSAIR CX750M 750W,
HDD Western Digital 10EACS (OS) - WD10EADS (backups etc.)

Thank you for any solutions!

cpu is bottlenecking you. those are not fully threaded games, which means most of the load will be carried by 1 or 2 cores. those cores are maxing out, forcing your gpu to wait for the cpu to catch up.

have you tried to overclock it? it doesn't seem like it's bottlenecking too horribly, a bit of an overclock on that cpu could do wonders for your problem.

Hello

I already reached an overclock on my CPU up to 4708.84 MHz (23.5 * 200.38 MHz) with a little bit of upping the voltage, but still have to work on further overclocking.

I will try bit by bit while gaming and keep you posted.

on bulldozer you can disable cores in the core modules. In your bios you should be able to disable the paired core in each module. which will give you some more single core performance. turning your hex core into a quad.
