[Matra et Alpine]

Hmm, not sure what you mean by "slope under" -- it's OK I don't speak ANY Polish
The rFactor Beta I have it's on a par with the current layout. I tihnk the original GPL track had the 60s "leap" and sever "dips" Which were you expecting ?

Some of the "issues" I put down to human perception. eg the Adenau bridge exit an the Ex-Muhle corner just never "feels" as much of a slope in a sim -- I put it down to my seat not tilting back enough

hmm, must find time to get back on-(virtual)-track and check out those again.
