To the glorious people on here coming up with the nonsense turning on "debug mode" inside Nvidia control panel """solves"" the issue btw here is WHY:
https://www.nvidia.com/en-us/geforce/forums/geforce-graphics-cards/5/314151/debug-mode/
"DEBUG lowers the factory OC to REFERENCE levels and this also lowers the draw on the PSU. DEBUG tells you something is unstable." Which is the same as lowering the power profile.
HUH. Weird. Hmmmm. How strange.
Same as turning off hardware accelerated GPU scheduling, which lowers the chance it happens under unstable power conditions, because it is a more hardware level access where critical timings are relevant. Tiny little lag in timings because of non stable voltages will cause the issue to happen more frequently. In the end, your PC is unstable because of voltage drops, either main board, GPU, or PSU issue.
