Good christmas for You!
I know a little bit, how HARD is developing in GTR2, with many cycles switching between photo-paint-program and GTR2 (Alt & Tab). Hours going up with this...
But, I want to suggest more tolerance with specific interests of single users, even when not in "mainstream". Compare it with flight-simulators (Microsoft, X-Plane, Fly!2): Some have a sliding controller for simulation DEPTH. Or compare it with versions of same track, beginning often purely without rain reflections. Why not use such simple versions? I like Nordschleife-0.9 most, although I have the newest version, running with acceptable fps´. Oh, I would like the version Nordschleife-1967 from GPL, but there is not such one for GTL / GTR2 (only GTR126.96.36.199).
So I´m driving mostly with Legends_Mod_for_GTR2´ Mini-Cooper in GTR2, although I have Original-GTL on DVD.
