I built this new PC about 10 days ago. It booted right up and benchmarked exactly as it should without overclocking. I've been played Starfield every day since with no issues.

 

I noticed a bubbling noise from my AIO radiator. So after some research, I decided to move my radiator up as far as it would go (even though it was already higher than the pump.) While I had it apart, I also did some cable management. I unplugged the USB connectors for my fan controllers, my front panel audio connector, and my 24-pin connector for my GPU. Once I got it back together, GeForce Experience told me I had a driver update for my GPU. So I installed the driver and ran Starfield. The AIO noise was gone, but my FPS was around 70-80 and it looked very choppy (I was getting 150-200 FPS before on the same settings.) CPU temps were 60-70°C under load, and GPU was 40-50°C.

 

The first thing I did was shut it down and check all of my connections. Everything looked fine. So I used DDU to roll back my Nvidia driver to the previous version. No luck. I triple-checked all of my connectors and then proceeded to take the PC apart entirely and put it back together. No change. I ran Time Spy on 3DMark and I actually scored slightly higher than my first benchmark right after I built it. The only noticeable change was my CPU and GPU temps were both averaging about 5-7° hotter, but the temps were still absolutely fine. And Starfield still looks horrible. I also tried completely uninstalling and reinstalling the game. I don't really have any other games to test because I don't have a reference for them from before I started having issues. I have some sensor logs from HWinfo, but I honestly don't know how to decipher most of it. It all looks fine to me.

 

XMP is enabled, and my Display Port cable is plugged into my GPU. I'm at a loss. Any help is greatly appreciated.
