In DevMode, yes, because you`re switching between the 3 diff fps modes and 4 x is switching it off, again.
Just wow, aiw is great now, this track is a must have. Endurance layout is my favorite, challenging, fast, slow corners after heavy breaking, mid speed corners, great elevation changes. Tested it with 44 cars and still the fps is very good. Thanks for all your work Nib, and thanks Hexa for you AIW tweaking. For sure my favorite track for Rf2
The OP has corner names mentioned? Are these shown anywhere as it would be good to include these in Crew Chief along with the other tracks
