Project CARSrFactor 2
Axis by axis
Execution8 vs 10
rFactor 2 leans harder on execution: Industry-leading tyre model rewards only perfect inputs
Reads2 vs 2
Even - both lean on reads about the same.
Variance2 vs 2
Even - both lean on variance about the same.
Optimization6 vs 7
rFactor 2 leans harder on optimization: Car setup depth rivals real engineering; fully solvable by experts
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
