head to head
DiRT Rally 2.0 asks more than Assetto Corsa, and the gap is variance.

Execution · Practiced Mastery
Hardcore racing sim where execution is everything.

Execution · Pure Mechanics
A punishing rally sim where commitment at speed and smart service-park decisions decide the leaderboard.
Assetto Corsa leans Execution (Practiced Mastery); DiRT Rally 2.0 leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Assetto Corsa
Demanding wheel control, braking, throttle precision
DiRT Rally 2.0
Millimetre steering corrections at speed define stage time
Assetto Corsa leans a little harder on reads, though the gap is small.
Assetto Corsa
Light online wheel-to-wheel reads
DiRT Rally 2.0
Solo time-attack format; no adaptive opponent
DiRT Rally 2.0 leans clearly harder on variance.
Assetto Corsa
Tire and track temp variance
DiRT Rally 2.0
Hidden surface cuts, gravel buildup and weather are unmappable mid-stage
Assetto Corsa leans a little harder on optimization, though the gap is small.
Assetto Corsa
Setup tuning, car-track combo mastery
DiRT Rally 2.0
Car setup and service-park tyre choices are fully solvable pre-stage
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
