Axis by axis
Execution8 vs 8
Even - both lean on execution about the same.
Reads0 vs 0
Even - both lean on reads about the same.
Variance2 vs 1
Dirt 3 leans harder on variance: Surface conditions and minor physics noise per run
Optimization6 vs 7
Gran Turismo leans harder on optimization: Tuning, car choice, and license tests are solvable
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
