Anyone can help? GPU issues

[genexis_x]

While gaming, sometimes I will experience micro shutter lags (the GPU usage will drop to 0% at the same time). As a result, gameplay is not smooth. It become even worse when I turned up the video settings. I checked CPU and GPU temperatures and they are perfectly fine. GPU driver updated to latest. Games I played are Dota 2 and CSGO.

 

Besides, FPS in Dota 2 is unstable. While I was playing with bots, I got around 100 FPS in the beginning. After a few minutes, the FPS will drop to 60-80FPS (without teamfights). FPS even dropped below 60 during teamfights. I play on fastest preset (low settings) and in my opinion, I got a below average FPS.

 

Specs are in my signature below. Anyone can help?

If it starts dropping after a couple minutes, it's some type of throttling. Check that your GPU and i5 are boosting properly via Aida64 or HWmonitor

But the temperatures are fine. Maximum 65 for CPU and 60 for GPU.

I didnt say thermal throttling did I? I said "some type of throttling" and so go check and see if your GPU clock(s) or your i5 are throttling for some reason.

Oh ok

Lots of stuttering when you don't have enough ram, that's probably the issue

could be some background program doing something no? installed or updated anything recently?

2.5ghz i5 is not exactly a beast for CSGO, could be the issue.

Turbo boost up to 3.5 (1c), 3.3 (2c) and 3.1 (4c)

I don't have any background programs running. Updated GPU driver recently but no change.
