It's hilarious when the authors of the mod have explained that there is way too much grip and that they did this on purpose for league racing. They said all along that there may be a more accurate "historic edition" at some point. The 643 may not be perfectly accurate, but it is going down the path of more accuracy than the '92 mod. I happen to enjoy it more and find it both more fun and more satisfying to drive, even though it's a bit more difficult to keep on the track.
Enjoy your chuckling. But if either of you is clueless enough to think that the '92 mod is representative of a real 1992 F1 car, then I will have to cry for you rather than laugh at you.
Most people prefer dumbed-down physics. That's why console titles outsell sim titles 100 to 1 (or more). Don't confuse fun with realistic. The 92 mod is better than a console experience because it has rF2 underpinning it, but the design philosophy is closer to console than sim. And it's a ton of fun. I just happen to like the '91 approach even more.
