I'm pleased be 5fps gained. Going from 15 to 20 is big difference. I'm rating it 5stars in advance, hoping that you'll again at least 5 more in next updates. That being said I was finally able to drive the track. And it is AMAZING. Big thanks for original creator and for SimTraxx making it happen in AC. It is awesome just needs smoother performance as all your tracks. And one more thing, you fall down through ground in hot lap mode.
