hi, i'm not sure how to help with the motion blur(hasn't been a problem on my side but maybe i just didn't norice, maybe changing some game settings could help?)
As for the levers, i'm not sure what kind of advice to give since i also had trouble with them, you have to click and drag fast, it did help when i was up close to them at the crossection in a way i could reach/see all of them to quickly click and drag, i'm not sure about the percision either, good luck!
