Someone has noted what's wrong with the track mod (see the in the comment section). But nevertheless I am waiting a for better version.
"Nice! This is a great impression of the real track. Smooth to drive, grip levels feel okay etc. The visual updates make a huge difference, bringing it up to a more current AC standard. Overall, I think this is one of your best tracks so far and probably as close as we will ever get to the real Le Mans. Not Tiago Lima's original conversion wasn't nice, only this is so much better! Now for the nitpicking.... Forgive me if I get a bit anal here. I spent quite some time researching an and texturing update for Tiago's circuit last year that for various reasons never got finished, so let's say I may have overdosed on Le Mans. Still have most of my files sitting around, should you want to use them.
These are the, mostly visual, issues I found after a couple of tryout laps in a reasonably slow car (gotta enjoy the scenery). Suppose some, or most, of them are to-do items but anyway; - Gantry structure at the end of the Porsche curves (Ford billboard) appears missing or somehow invisible? - Nissan billboard, trackside next to the gantry mentioned above, was removed a couple of years ago. Haven't been replaced as far as i can tell. - Outside (left side) wall along the Ford chicanes by the Porsche Center doesn't look quite right, could be that the access road has been moved but I will have to look closer to be sure. Also missing FIA Road Safety banners. - Missing tire barriers at the chicanes on the straight. - Grandstands lack rooftop adverts. - Gant banners/billboards have a different, stylized font on blue backround rather than black - Banner on the fence at Indianapolis should be Gant, not Porsche. - 24h logos, with a few exceptions, should have blue background for the 2017 race. - Circuit de Mans logos varies a lot in appearance over the track. The ones by Mulsanne corner are notably darker than the ones along the pit straight, for example. - Forza/Xbox banners and signs missing at Tertre Rouge and the chicanes. - Slightly muddy or dark appearance of some banners and billboards. -Some trackside objects are very dated. Those are faults of the original track though and easy to miss, especially without a bit of local knowledge."
