So for a lot of people Patch 2.13 has been a great performance boost; though I personally have a 40 series GPU and intend to keep using DLSS since it looks better (FSR 3.1 when CDPR?) FSR does actually gain me significantly more frames at the cost of some visuals.

However some of you (like me) will have initially had a significant FPS drop compared to pre-patch, along with weirdly low GPU utilization and loss of access to frame gen for 40 series cards. The fix is simple, go into windows graphics settings and enable hardware accelerated GPU scheduling. For me at least that solved all the above issues and I hope it can for some other people too.
