head to head
iRacing asks more than Call of Duty: Advanced Warfare, and the gap is optimization.

Execution · Pure Mechanics
A futuristic Call of Duty whose exoskeleton boosts made aerial movement king.

Execution · Practiced Mastery
Hardcore online racing sim with PvP wheel duels.
Call of Duty: Advanced Warfare leans Execution (Pure Mechanics); iRacing leans Execution (Practiced Mastery).
iRacing leans a little harder on execution, though the gap is small.
Call of Duty: Advanced Warfare
Exo boost-dodging raises the mechanical ceiling sharply
iRacing
Brutally precise wheel inputs required
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Advanced Warfare
Predicting human boost paths wins gunfights
iRacing
Serious wheel-to-wheel racing vs humans
Call of Duty: Advanced Warfare leans a little harder on variance, though the gap is small.
Call of Duty: Advanced Warfare
Spawns and supply-drop loot add randomness
iRacing
Weather, tire wear, mechanical variance
iRacing leans clearly harder on optimization.
Call of Duty: Advanced Warfare
Movement tech and class builds are learnable
iRacing
Setup, strategy, iRating progression
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.
