I don't know what happen it was working fine before, but something knocked something off & now when I start my engines, instead of seeing a normal smoke, now I see like block patches of smoke.. Not the smooth Smoke that the game was doing originally.. I really don't want to have to take the entire flightsim off & restart from scratch.. So i was kind of hoping maybe someone on here good give me something to try to work with to avoid that awful mess.. However everything looks good on the display option.. Thats really the only thing really i could think to check to see if something got wacked out of shape but everything look alright.. However anytime I start my engines lately i'm not getting the real smoke affect but instead like the graphics are off or something..
