Yo guys,I got a little problem here.
I got stuttering in these games.These are:GTA 5,Euro Truck Simulator 2.
I run them both on very high,no lag at all(30+FPS),but I got very big framedrops at some points.
I spot the light indicator down to my power button on my case blinks constantly when I get stuttering.I notices in task manager,that in stuttering my CPU usage blows up to 80-85 % from normally 55 % when I play GTA 5/ETS 2 or whatever other game.
CPU:Intel Core i3-3320 3.3 GHZ
Gigabyte GTX 660 2 GB(3GB with shared memory)
HDD 2TB Seagate
Windows 7 SP1 64 bit
Fortron 600 W PSU
Asrock H61M-DGS
8GB Ram @ 1600 MHz(6,96 GB usable due to shared memory)
What it can be?CPU,HDD?GFX?To mention,the Windows is old here and I have AVG PC tuneup installed.No antivirus for now.NVIDIA GEFORCE Experience running in background aswell.Can it be a virus or something?All replies appreciated.
