If I had to guess, maybe the shadow or AA setting are too straining/taxing for your GPU when it is dark.
Thanks, this I didn't know yet! Hopefully this helps the OP and anyone else with such issues.I know what this is!
These are artifacts caused by the new FidelityFX Dynamic Super Resolution mode. The setting that lowers your resolution and uses some clever algorithms to keep visual fidelity. It seems to not be working as intended right now.
Go to your settings, and change "FSR Mode" to off.
According to the PTS patch notes, this issue should be resolved with the new update. Until then, just set it to off.
