[BUG] ME1 Framerate drop after killing docile salarians on Virmire

AMD Ryzen 7 2700X

32 GB RAM

NVidia RTX 3080 version 466.27

Windows 10 Pro 20H2 19042.985

Does not seems to be hardware specific, same issue with my gear:

nVidia RTX3080 (Driver version 466.27)

Intel(R) Core(TM) i9-10850K

32.0 GBRAM

SD NVME WD Black

Windows 10 64 Bits (up-to-date)

I've experienced the same thing in both instances. After the Dr. Heart cutscene and the insane Salarians cutscene the frame rates drop. Loading from save stops it, repeating the action repeats it. You can bypass it on Virmire by not killing the Salarians. You cannot bypass the Dr. Heart one. The Virmire cutscene is low enough FPS and deep enough into the mission to be, uh...quite literally unplayable. You're not finishing that mission to get back to the Normandy. The Dr. Heart one doesn't give as much of a drop and the proper behavior is restored after returning to the Normandy, which is a quick, enemy free jaunt away.

Same issue here, instant fps drop after killing the salarians.
Quick save/quick load does not work.
Restarting the game does not work.

I also got the framerate issue with Dr. Heart in the MSV Fedele and it solved itself when coming back to the Normandy.

Attached DxDiag.txt

GeFroce driver version is 457.51

Same problem after killing passives in cell on Virmire.  DXDIAG log attached.

Exact same issue after freeing the Salarians.
