I've had a long conversation with intel support on facebook now i post it here.
I'm using intel i5-11500 cpu, detailed info in the SSU and GCC.
I found bug in drivers.
In driver version - 220.127.116.1166.
I have stutters and freezes in CS GO, but in DOTA 2 everything seems fine. CPU fequency is normal.
In driver version - 18.104.22.16867 BETA
Stutters and feeezes in CS GO are gone, but in DOTA 2 strange thing happening to CPU frequency it lowers to default CPU clock - 2700Mhz. Same happening in CS GO but it lowers to 3800+ MHz sometimes. But overall it's on maximum.
How can GPU driver affect CPU freq?
Although if you go to windows control panel and turn performance to max CPU frequency normalizes in both games.
I've tried clean installation, etc. It doesn't help
Here's detailed look of the problem:
Maybe it's not even bug, but some energo eficienty feature. But why it works on DESKTOP PC? I don't use notebook or something where this feature would be useful. This is shouldn't work like that. Can some dev answer what is this?
