[SOLVED] How do I diagnose what is causing my micro stutter in game

[PlasticQuarters]

My specs are

Video Card: EVGA RTX 2070 XC Gaming
Memory: Corsair Vengeance LPX 16GB DDR4 3000MHz
Hard Drives: SAMSUNG 860 EVO 1TB SSD Western Digital Caviar Black 1TB HDD
Cooling: NZXT Kraken x62 280mm
Monitor: ASUS ROG Swift PG278QR 27" 1440p 1ms 165Hz

I have gotten micro stutter when playing video games since I bought it regardless of the graphics settings. Even after a fresh install of windows it continues. How do I diagnose what is causing the issue?

Micro stuttering in which games?

 

[cherry blossoms]

1st question, yes , which games? Many simply aren't going to get to 165Hz consistently, even on a 2080Ti. 10% and 1% low framerates are relevant. Depends on your personal sensitivity to frame drops.
In context, for GPU workload:
4k 60Hz is 497,664,000 pixels a sec
2k 144Hz is 530,841,600 pixels a sec
2k 165Hz is 608,256, 000 pixels a sec

Windowed or full screen mode? Do your G-sync settings match? This is assuming you are using a displayport cable and that your hardware is properly handshaking for this.

Background processes? Overlays? Cloud saves? Does a clean-boot setup help?

Windows 10 does have ALOT of cruft that can be gotten rid of. All that background telemetry churn and background tasks adds up.
