I have found that stuttering while in-game even with high fps was caused by NT kernel & system ( system.exe )
and this issue was unknown by the people who had this issue and couldn't figure it out but i finally found the cause
and i tried to find a solution for this but it's really hard to stop the system from using the " copy " feature on AMD gpu
so what i'm saying is that even using the official driver from the computer/laptop manufacture it's still the same
even tho i was on windows 7 and i had this issue and i was confused by that time which i didn't know about it before
and before this happens, there was absolutely no stutters or anything and it was super smooth until this happend after 20 minutes or something of playing
The gpu i'm using for gaming is Amd radeon r7 M440
And i tried several things and still it didn't work for me :
Day Later -
I have this same problem but opposite, I had my GPU on the copy engine and it was working fine that's how nzxt shipped it to me btw, but then I had to reset windows 10 and now it's on the GPU 0 - 3d engine and it lags and stutters and doesn't stay at 99% like there's a bottleneck but there was not before I reset.
when it was on the copy engine every game went to 99% right away and ran very smoothly now on the 3d engine it doesn't stay at 99% and fluctuates between 50% and 99% as it needs to use the GPU it uses it instead of using it all at one time like before. so frustrating.
