Some graphical feedback: There is a light/shadow seam at the 3rd cp (fuel line). And the sawblade at red spawn doesn't spin. It has some motion blur effect on it, but it remains static which makes it look weird.
There are two other things I noticed, although I can't tell if they 100% map related. In the final area were two textures flickering when I was some distance away from them. It got better the closer I got.
And the console was flooded with strange error messages regarding the bone setup of the scout model (I was playing Scout on my playthrough) after capping cp 3.
