I'm experiencing a rather severe CPU bottleneck problem that I initially thought I had narrowed down to Ray Reconstruction but is now happening whether or not that is enabled or not, or, maybe it's situational and some scenes / environments are so demanding that it's dipping down even with it disabled.
I posted this over in the game's Steam Discussion forum and now, having ruled everything out, with no other CPU or Memory consuming processes running, with the game's executable running with Very High privileges in Task Manager, I'm left to conclude that there is nothing that can be done about this performance issue short of reverting to an earlier build pre-2.01, it just sucks because I just spent like 45 minutes creating a new character and have already invested roughly 4-6 hours in a new play-through and all of this will not be compatible reverting to say 2.02. My research is indicating that this is a fairly widespread issue affecting users with fairly robust hardware, all of which implicate RT / RT Ray Reconstruction, and Path Tracing, and I'm referring to the CPU side of things.
To describe the issue in sum, with a 12900k @ 5.1 GHz actual (0 AVX) across all P-Cores, (E-Cores disabled) and a 4090 @ 2850 MHz, both components under tons of water (45C GPU and CPU, 31C water temp, inaudible fan speed), 4x8 4000 MHz DDR4 with tight timings, basically the fastest DDR4 you can possibly use, the GPU utilization and FPS will start out at 99% and 65 FPS loading a save or coming out of the menu but within 60 seconds it will drop down to 80% and 57 FPS. I've tried turning up DLSS quality from Auto (Balanced) to Quality with the intent of at least putting the GPU to work but the utilization simply stays the same and the FPS goes down to the mid 40's. This is at 7680x2160 (dual 4K) with FG enabled, RT: Psycho, everything else maxed except Crowd Density: Med, and Ray Reconstruction and Path Tracing disabled. Initially I believed I had narrowed down this problem to Ray Reconstruction but now, as of this evening, it's presenting the same problem with it disabled. I'm in the area with the first mission with Jackie, retrieving the bot from Maelstrom, and in this area it's presenting this issue. I'm so frustrated with this that I'm ready to redownload 2.02:

Given how widespread the problem I I presume the devs are aware of the issue? Read the comments below the following video showing the FPS drop between 2.0 and 2.1.

If I could use all 99% of my GPU that would be fantastic, oh and when it dips down to 80% after 30 seconds of loading a save or exiting a menu the CPU usage is at 20%, golf clap. I have other gripes with this update, I tried to help NCPD fight some goons and didn't shoot at them at all and after I helped them dispatch the goons they all went completely agro on me? Also, the "there are actions without key-binds" bug is super annoying.

DLSS Ray Reconstruction causing performance to drop after patch 2.1

I have this very same problem and independently narrowed down the issue to Ray Reconstruction. The issue occurs separate from Path Tracing, simply enabling Ray Reconstruction with RT causes my CPU utilization to drop from 95% down to 80% (12900k @ 5.1 GHz, E-Cores disabled, 32GB 4000 MHz DDR4). This drops my FPS from a completely playable 65 FPS to 55-57 FPS when it happens (7680x2160, RTX 4090 under water block @ 2850 MHz, FG enabled, DLSS Auto).
For whatever reason there is also flickering with Ray Reconstruction enabled? This problem wasn't present before the latest patch, in fact, I was around 65 FPS with Ray Reconstruction enabled without the CPU bottleneck (RT: Psycho).
Any way to pass this on to the devs? Are they aware of the issue? Thanks.
