My new card allows me to finally turn resolution scale to 2.0 without causing stutters, so it looks clear like it should.
But GeForce experience says it's resolution is at 1280 x 720. This is separate from res scale.

There's no resolution option in-game.
Is this resolution related to the textures, or just tied to res-scale (rendering of everything)?
Because of 2.0 of res scale is the best quality I'll get for textures and such, I can live with that.
