Bathurst 2016, Barbagallo, Adelaide look the nicest. Most others have been updated to be DX11 friendly, but probably require some further updating of shaders, objects etc to look really spectacular...
We have a series starting Monday the 15th Details at http://www.xfactorracing.com/index....ships/11178-2018-aussie-legends-summer-series SS
There's a Bathurst 2.0 floating around that was updated to DX11 (the official/3pa version hasn't been yet), do a google search and you'll find it. As others have already said some tracks have been updated, some haven't but that doesn't mean they're not playable.
yeah someone took the 2016/3PA/Official version, added relevant ad-boards and stuff for DX11, works well with PP Effects on from what I saw.
To be honest, the version I've got now is pretty good in DX11. Only thing wrong with it is that it's missing the 'Mt Panorama' sign up by McPhillamy/Esses/Dipper on the side of the mountain. It's like the Hollywood sign; doesn't look right without it.
Here's the Aussie Legends site: has links to xfactor made or converted tracks: http://www.aussielegends.xfactorracing.com/index.php/downloads/category/3-xr-tracks
20 would be a stretch for my old legs, 10 is about my limit. I'll stick with the TCM lap numbers. Just working through the 2015 series atm. Using the XY GTHO.
I found v1.81 online is that yours? If so I've found a bug with Fast Rolling Starts (29AI used) in that it doesn't work properly, the "Formation Lap" just continues on forever, also the Turn 2 "bump" needs to be flattened out quite a bit as it's quite harsh. Other than that (and a few other minor inaccuracies I can live with) it's a very good version so thanks for bringing it to us, if it's nothing to do with you apologies and ignore this post
