I noticed very slight stuttering problems cyclically. And I thought it was a manufacturing defect in the GPU.
After changing the PSU cables, play with the Nvidia Control panel options and such. I remembered that I had a similar problem on the RK84 (cyclic problem) and realized that the problem is with the Software.
Stutters every 3-5 seconds when device (GPU) is enabled in SIGNALRGB software.
Hey, I had the same issue and emailed them and got a reply. It was something along the lines of
“We detected a lockout in the nvida api” and they said they could not fix it on their end. The solution was to disable your gpu from being controlled by SignalRGB. This totally fixed my stuttering.
@Christian - NVAPI being loaded is enough to cause stuttering, iirc.
So yes, unfortunately the only solution is to skip using the Nvidia bus for customers with problematic products. We use an Nvidia library to talk to nvidia stuff, and this is the root of the problem.
