Got a copy after the last patch. Graphically it's very nice even on medium settings (my rig is showing it's age). I'm surprised however, given DTG's own representation on how the physics were improved over TS20XX and several subsequent patch fixes, that the first loco I got to operate felt like a lightweight hot air balloon. Almost insta-acceleration with minimal power application, and then almost insta-stop with minimal brake application. I was hoping for something that was more 'meaty', more robust feeling-- which another sim offers, just sans the super nice graphics. Hopefully DTG will get it together and we'll have the best of both graphics and physics.
