Absolutely fantastic work and a must-have mod (just like all of LilSki's tracks).
However, with this first release, I do have a couple of niggles, the major one being the amount of trees that 'pop-in' in the distance. I'm playing with max settings so this shouldn't be an issue, and for comparison's sake, it isn't an issue with any of LilSki's other tracks, or tracks such as CTMP or Nordschleife, both of which feature a lot of trees. Driving down the start / finish straight and seeing trees suddenly appear in the distance breaks the immersion a little for me.
The second, much smaller, issue I have is with the cones. I've been driving around VRC's Barber Motorsports Park a lot recently, and after sliding into the cones at Calabogie, I was slightly disappointed that my car went through them rather than push them around like at Barber.
I know that these issues will improve with updates, and when they do, I'll be happy to remove this four star rating and give it the five stars that it truly deserves.
