Lag and Stutter issues

I have a fairly good PC, and I notice severe lag when I drive in high speed in games like Watch Dogs 2. This only happens after I play for 30 minutes. Other games, like Metal Gear Solid V stutter a little while riding the horse or running around. Also, WD2 takes a very long time to load. Even old games, like Shadow of Mordor stutter a little after playing for a few hours.

My Specs:
GPU: ZOTAC GTX 960 AMP! 4GB Edition
CPU: AMD FX-8350
RAM: Corsair Vengeance 2x4GB
HDD: WD Purple 1TB
Motherboard: MSI 970 Gaming
PSU: Corsair 650w

WD2 is literally unplayable after a while, and sometimes, it just gets stuck. I can hear the audio for a while, but then I'm forced to shut my PC down.

Thank you

If this only happens after a period of gaming, it sounds like you might be hitting or getting to the thermal threshold of the card, and is throttling to save itself from getting hotter. You could run something like msi afterburner or a similar program and look at the usage/temperature graphs when it starts stuttering. If the temperature hits a peak and the mhz/usage goes down at the same time, that's most likely the problem

No, the temperature is not the problem, as when I was playing, I go around 80 for the whole session. The real problem seems to be in the GPU usage part, as it was around 95 and 100% when the game was not lagging, but suddenly went down to 0 and 20% for no reason at all.

What about your CPU? What do the temp and CPU utilization numbers look like? Also, your GPU may just be going south. My old 570 did what your 960 was doing until I downclocked it, turned out it couldn't run at stock clocks anymore.

But my PC is pretty new, so I don't think the GPU is going bad this soon.

Anything can go bad at any time. New doesn't mean it's guaranteed to last a long time until it fails, just that it's less likely to if it was working in the first place.

80c is unusually high temps btw. Should be in the mid 60c range. You might have a bad thermal paste job on the card, or the fan isn't ramping like it should. Try something like MSI afterburner or EVGA precision to set an aggressive fan curve.

Can you please guide me in doing this please?
