This is the exact problem I am having.
I installed the new nvidia driver. Did all the DLSS stuff ( Releases · beeradmoore/dlss-swapper · GitHub _)
and got 120 fps looking nice - after 30 minutes of play down to 10 fps.
I rolled the driver back, undid all the DLSS options, hit optimize in nvidia app.
120 fps …for about 30 minutes, then literally 10 fps.
I happened to look at hwinfo (to look at temp to see if I was being limited by temperature) and noted that inspite of 99% gpu usage it was below 200 w (can usually peak at 450w).
I tried another high intensity gpu app (bit coin mining), and it popped right to 400w.
wtf microsoft. Any fixes out there?
