Hi i am hoping someone can help as i have had this issue for months now and its driving me nuts.

components:
crusial 258gb ssd
fx8350
gtx 1060 6gb oc edition
windows 10
16gb hyper x ram
nzxt x52 liquid cooler
70mb download 20mb upload 5ping.

Whenever i play cs it starts off really smooth sitting between 200-300fps stable in most maps. As soon as i leave the spawn i get micro stutter/jitters where characters stutter for a split second. My mouse also goes slugish and this is all while still having high fps. I play every setting on low in game and have tried every fix i could find from fresh driver installs to reinstalling windows,Using nvidia inspector, A game reinstall, stopping/disabling startup programs, editing registry and also monitoring my cpu/gpu usage with programs like CAM and HW monitor my cpu and gpu never go above 50c and i have had enough now, So stuck on what to do so if anyone has any ideas it would be much appreciated.

Thanks
 



Sorry Lutfj completely forgot to add, My mobo is a msi 970 gaming board, PSU: Corsair CXM 750W Semi Modular 80+ Bronze Power Supply - PSU is just short of a year old.. I have not touched any bios settings yet other than the cool n quiet stuff for amd.. Thanks

As soon as we can run out of spawn the mouse has a sluggish feel like the sens is slower and then it starts jolting and stuttering?
