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 · Pure Optimization
An open-world shooter-RPG won by perk routing and weapon mod optimization.

Optimization · Practiced Mastery
A demanding action RPG where dodge timing meets alchemy build planning.
Fallout 4 leans Optimization (Pure Optimization); The Witcher 2: Assassins of Kings leans Optimization (Practiced Mastery).
The Witcher 2: Assassins of Kings leans a little harder on execution, though the gap is small.
Fallout 4
FPS aiming, VATS softens demand
The Witcher 2: Assassins of Kings
Tight dodge and parry windows
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 4
Scripted enemy AI
The Witcher 2: Assassins of Kings
Scripted enemy patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 4
Loot and legendary rolls
The Witcher 2: Assassins of Kings
Some loot and alchemy variance
Fallout 4 leans a little harder on optimization, though the gap is small.
Fallout 4
Perks, settlement, weapon mod planning
The Witcher 2: Assassins of Kings
