I have T:ANE, TS12, TS2010 and TS2009 however I only use T:ANE and I haven't bothered to register the others as there is no point due to the Trainz lifecycle (I only bought them for routes and content). I had TS2006 a while ago but I haven't a clue what happened to the disk. Again, I didn't register it as at that time I didn't even know the download station was a thing and I was only interested in driving trains.
Its odd to see how wild performance of T:ANE is across so many systems. Some people have absolutely abysmal performance, even on high end rigs while others seem to have superior performance to pervious versions of Trainz. T:ANE performs much better than TS12 ever did on my PC. Routes that see 30-40 fps in TS12 get up to the 80's with V-sync turned off on T:ANE. If Matt wanted to, the IRM project group could work together to make a TS12 compatible version, however that would require a lot of work and the T:ANE version of the route has a long way to go before it's ready for release.
@Matt I will put some pics up when I get home later today and possibly a download link for some of the finished content if I feel like its ready.
