Gonna have to disagree with you there. I asked around beforehand and the VheEth track got everybody's vote as subjectively the best base to update.
The Vencialo track seems to be inferior in just about every way, to my eyes anyway.
shrugs
Edit: just to elaborate; the road is glass-smooth with no feedback, lots of textures have broken alpha, trees and tree walls look unnatural and have a lot less layered depth, it uses old clockwork 2D grass, road textures look bland, geometry is a lot more basic (compare the staircases to the rear of the Mercedes stand, for example), many logos are stretched or squashed... all IMO of course.
That's not to say further visual improvements couldn't be made to the VheEth track. It's perhaps a little low-contrast overall, so stronger vao patches and trees tweaked to have more contrast might sharpen the whole look. I'll maybe look at these in an update.
