During gameplay I get occasional stuttering and frametime spikes about every 5-60 seconds. Almost every game I play has high fps, but every 5-30 seconds I get a stutter. It happens in every game, and even in benchmarks like Heaven and Valley. The stuttering started about 3 weeks ago, although it wasn't there before.
My PC:
GTX 1660
Ryzen 2600
16GB 2 sticks of ram 3000 CL16
Gigabyte B450M S2H Rev 1.0 Bios F61
PSU THERMALTAKE Smart 700W
SSD Smartbuy Jolt 480GB
HDD TOSHIBA DT01ACA100 1TB
HDD Seagate BarraCuda 2TB
Temps under load:
GPU: 72c
CPU: 56c
Things I have tried
Hardware:
Unplugging everything except mouse and keyboard
Different DP/HDMI cable
Different PSU
Different graphics card (GTX 970)
Unplug USB 3.0 case front panel from motherboard
Swapped out the RAM modules.
Software:
Reinstall windows many times (Windows 11 22000.120, Win10 21H1, 21H2, LTSC 1809).
HAGS on/off
VSYNC on/off
NVIDIA LLM On/Off/Ultra
CPU/RAM/GPU Stock/Oc/Undervolting
Latest nvidia driver / old nvidia driver (458.36)
All background programs off.
All sorts of power plan settings (1Usmus, High Perf, Maximum Perf)
GameDVR Off
What should I do to make the stuttering stop? What could be the culprit here?
