Dirt 3rFactor
Axis by axis
Execution8 vs 8
Even - both lean on execution about the same.
Reads0 vs 1
rFactor leans harder on reads: Online wheel-to-wheel racing adds slight opponent prediction
Variance2 vs 1
Dirt 3 leans harder on variance: Surface conditions and minor physics noise per run
Optimization6 vs 6
Even - both lean on optimization about the same.
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
