This issue started only a few hours ago, have literally never seen this before but now cannot fix it. At 30fps the game runs as expected, but when I uncap frames or set to 240fps (my monitor refresh rate) particles start flickering in and out of existence, making root of nightmares completely unplayable as you can see in the attached video. This affects other things like ogre beams, taken enemy spawn animations, etc. I've cleared the Steam download cache as recommended by Bungie support in a similar post, have latest graphic drivers, looking for advice.
