head to head
Silent Hill 2 (2001) asks more than Amnesia: The Dark Descent, and the gap is optimization.

Optimization · Light / Casual
A first-person horror about exploring a haunted Prussian castle.

Optimization · Pure Optimization
A psychological horror experience where puzzle knowledge and avoidance routing matter more than combat skill.
Amnesia: The Dark Descent leans Optimization (Light / Casual); Silent Hill 2 (2001) leans Optimization (Pure Optimization).
Silent Hill 2 (2001) leans a little harder on execution, though the gap is small.
Amnesia: The Dark Descent
Stealth and hiding, low demand.
Silent Hill 2 (2001)
Clunky combat is intentional; survival over precision
Silent Hill 2 (2001) leans a little harder on reads, though the gap is small.
Amnesia: The Dark Descent
Monsters follow scripted patrols.
Silent Hill 2 (2001)
Monsters follow simple fixed behaviours, never model the player
Silent Hill 2 (2001) leans a little harder on variance, though the gap is small.
Amnesia: The Dark Descent
Minor encounter variation.
Silent Hill 2 (2001)
Some item placements are unknown first time; fixed thereafter
Silent Hill 2 (2001) leans clearly harder on optimization.
Amnesia: The Dark Descent
Oil and sanity management is shallow.
Silent Hill 2 (2001)
Puzzle solutions, route knowledge and weapon use are fully learnable
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.
