Gonna try it now. The game has its share of bugs though, wouldn't be surprised if the freezing was something else. I've been playing for the past hour or so, but then randomly lost the ability to enter settings from within a flight, and my hud on external cam disappeared entirely. I was able to play for another 15min or so before I quit, and it never went back to the main menu, just got stuck on a black screen when I tried. Had to task manager force quit. Still seems a little beta-ish.Even on a still ultra high res screenshot from guru3d, I couldn't tell the difference between high and ultra so it could be more physics based/draw distance than textures. You should definately be ok with medium though.
