Beter to test these by yourself? Maybe you like visual bad made tracks because the drive is so smooth and very realistic. Or what if your PC has problems in maintaining a decent straight FPS.
First check out the available track and enhance mods/versions on the Breathe list and on Overtake. Install them.
Before driving, I look around focusing on some objects like trees/rocks, the road and the indication about shimmer/jaggies.
Then a quick drive on how the tracks drives.
To make room on my SSD, I did a couple test on this Woodland circuit and on some tracks, the trees and hedges are made from crapwood and are looking like a cardboard display. Despite it is a very good made track, the track from
@LuisB https://www.overtake.gg/threads/nordschleife-1967.268755/ I did drive a couple of weeks ago, does face this problem. While I think especially for a woodland track near the road trees and hedges should be well made. But maybe this is only noticeable when driving in VR mode and not on a single monitor.
If wanting the best made vintage track, I can advise to download all
@fat-alfies tracks, these are the best made free vintage tracks you can find for Assetto Corsa.
