@Nedo68 i know im years late, but i think the particles flying into the air is caused by the high fps. many games especially from early 2010's uses physics that update every time a frame is rendered.
if this is the case with dust and snow particles in this game, then that can explain why they fly much higher. to explain simply, 30fps is the standard physics, where particles behave as expected. 60fps could double all physics effects, meaning things like speed, weight and things like that would all be multiplied, and so on the higher fps you have.
when i watched a video with 60fps gameplay, the particles were annoying, but the game was still playable. but when i tried myself on a 144hz monitor, the particles went absolutely bonkers to the point where my only hope of seeing was to go to 1st person camera.
so long story short, there may not be a fix unless you're able to edit the code that makes the particles behave properly regardless of fps. if its too annoying, you might wanna try to find a way to lower the fps limit till the problem isn't very noticable. maybe 40fps sounds alright
