I recently bought a Dell G5 5505 SE, like a month ago, but ever since the firsts days I have this problem with all of my games, which after 10 to 20 minutes the frames can drop from 120 to 6 fps for 1 or 2 minutes but repeats in a cycle. Also on 3D modelling softwares like Rhino or Fusion there's stuttering on the view and the UI is buggy which kind of affects workflow, I tested this softwares on other computer and there works perfectly fine. I've also seen that many users of G5 or G7 series have this problem but there isn't any solution yet.

I have already tried updating graphics softwares, tweaking AMD and Windows settings, activating high performance and system diagnostics (none). Of course I always use it plugged in. What can I do to have an optimal experience?
