head to head
DCS World asks more than Elite Dangerous, and the gap is reads.

Optimization · Practiced Mastery
A study-level combat flight sim where mastering each aircraft's real systems is the price of entry.

Optimization · Practiced Mastery
Galaxy-spanning space sim about flight and trade.
DCS World leans Optimization (Practiced Mastery); Elite Dangerous leans Optimization (Practiced Mastery).
DCS World leans a little harder on execution, though the gap is small.
DCS World
Precise stick-and-throttle handling and BFM have a high ceiling.
Elite Dangerous
Flight controls, docking, combat aim
DCS World leans clearly harder on reads.
DCS World
Multiplayer dogfights against humans reward genuine prediction.
Elite Dangerous
Light PvP reads, mostly PvE
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DCS World
Sensor fog of war and unseen contacts hide information.
Elite Dangerous
Procedural galaxy, mission variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DCS World
Full-fidelity avionics, weapons and tactics are a vast learnable system.
Elite Dangerous
Ship build, trade routes, engineering grind
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.
