Question

do force4x MSAA save battery

Answer 1

No, using force 4x MSAA (Multisample Anti-Aliasing) does not save battery life. MSAA is a graphics technique that smooths out jagged edges in 3D graphics, improving image quality but also requiring more processing power. The increased processing power used for MSAA can drain the battery faster, so enabling it will consume more power rather than saving it.
