head to head
Dead Rising asks more than Assassin's Creed III: Liberation, and the gap is optimization.

Optimization · Practiced Mastery
A stealth-action adventure where Aveline swaps social personas to move through 18th-century New Orleans.

Optimization · Pure Optimization
Mall zombie sandbox where a strict 72-hour schedule turns survival into a routing puzzle.
Assassin's Creed III: Liberation leans Optimization (Practiced Mastery); Dead Rising leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed III: Liberation
Lenient parkour and counter combat set a low ceiling
Dead Rising
Crowd-clearing melee and psychopath dodging are modestly demanding
Assassin's Creed III: Liberation leans a little harder on reads, though the gap is small.
Assassin's Creed III: Liberation
Guards follow patrol scripts without adapting
Dead Rising
Zombies and psychopaths follow fixed scripts
Dead Rising leans a little harder on variance, though the gap is small.
Assassin's Creed III: Liberation
Light patrol and notoriety randomness
Dead Rising
Survivor AI pathing and zombie crowds add run noise
Dead Rising leans clearly harder on optimization.
Assassin's Creed III: Liberation
Persona disguise system and mission routing reward planning
Dead Rising
72-hour clock makes routing, scheduling, and PP farming the game
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.
