time to come back to GP4 for sure - as SchueyFan said
early this year my desktop pc crashed and having not much time for leisure anyway I nearly forgot about GP4
now with longer autumn evenings I was able to get my rig going again, GP4 being the only game I have played the last years I found it on the hd, started it to test the hardware and was hooked again
... next stop: grandprixgames.org ...
thank you to Hega for the conversion and the guys who did the the HD textures
thank you to TomK for lower lods and position files
it is awesome to have a complete new carset
alas: I have a small problem with the Lotus - the exhaust area and the end of the floor are white (both cars, in GP4Builder all looks allright)
