Many thanks for all the answers.
I´m working with Nvidia Inspector and searching the best setup for the AA. I set "Override application...", but it seems the game not consider that setting: I can set the AA with the game slider, but the settings via Inspector not modify the AA in game. Is it true? Can we set "Override..." in AA in Inspector and set the AA? It´s seems not...
Without AA via game (and graphics horrendous), I obtain 29 FPS. But with only a point in the AA slider, my FPS down to 10 FPS. Frustrating...
Best regards.
