As stated in the title, during the MR 27 test (both practice and the real thing), the game stuttered/froze for half a second every time I killed one of the red eximus units. My game never drops below 60fps, and did not either during this test. It simply seemed to stutter every single time a red eximus unit was killed, without fail. I used the Kuva Bramma, but even when killing with melee or parazon finishers the stutter still occured.
I am on PC (Desktop) with a 3060ti and and all graphics settings on High.
