The Track is absolutely amazing!
Very detailed and realistic, top notch job.
Been at Borgloh irl before and I can tell it's a 10/10 mod.
But there are some optimization issues, I usually never
get the 99% CPU Warning, but here I get it.
Also it freezes when I exit the game.
The track has many many textures, I know but it should work.
Can you try disabling:
[MODEL_3]
FILE=grass.kn5
POSITION=0,0,0
ROTATION=0,0,0
in models_layout_a.ini?
maybe this helps.
