head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Practiced Mastery
Immersive sim where stacking powers and routes unlocks creative kills.

Optimization · Practiced Mastery
A real-time RPG carried by ascension-grid routing and magic crafting.
Dishonored 2 leans Optimization (Practiced Mastery); Final Fantasy XV leans Optimization (Practiced Mastery).
Dishonored 2 leans a little harder on execution, though the gap is small.
Dishonored 2
Blink, parry, and aim timing matter.
Final Fantasy XV
Real-time combat, modest input demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dishonored 2
Guards scripted; alert patterns fixed.
Final Fantasy XV
Scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dishonored 2
Patrols and chaos rating vary lightly.
Final Fantasy XV
Loot and ascension variance
Dishonored 2 leans a little harder on optimization, though the gap is small.
Dishonored 2
Powers, routes, ghost runs deeply solvable.
Final Fantasy XV
Ascension grid, magic crafting, party planning
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.
