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.
Small update:
I was just trying some things to get latency down and while I was in Nvidia control pannel decided to give:
"Texture filtering - Anisotropic sample optimization"
A try. I can confirm that I saw almost no shimmering and it dropped my GPU/CPU useages from about 70% to 50%. I'm playing at 1080p with DLSS on balanced and settings maxed. My system is a 32GB of ddr4, an AMD 3700x cpu and an RTX4070 GPU for reference.
Thought I'd add it to this post because it seems to be a fairly substantial performance boost with no downside, at least on my setup.
Tiny update:
Changing multi-threaded optimization from 'auto' to 'on' in the nvidia control pannel or your GPUs equivelent appears to result in a small but noticable boost to performance on some setups. This is due to windows often having auto default to off, though you should do this on a cyberpunk specific profile as it can break older applications.
