Anti-Aliasing

[sms1202]

Does having Anti-Aliasing tuned of give a FPS boost. Lets say TOMB Raider (2013) with FXAA turned on gives 45 fps. Will it increase to 50-60 fps?

[Godlygamer23]

You can increase your frame rate by turning off AA, yes.

[TR-808]

If you turn it off it drastically increases FPS.

[Techicolors]

generally yes, you'll gain more frames with AA off. however cheap techniques like FXAA do very little to frame-rate as it essentially blurs the image a bit to reduce the aliasing. more appealing techniques like MSAA or supersampling tank frame rates, though some games handle MSAA better than others. new AA methods like TXAA (exclusive to NVIDIA cards) deliver great image quality without much decrease in performance

Yeah, it turning OFF AA will increase fps, by quite a bit actually.

If you're GPU-bound, then yes.

What AA does is that it squeezes more pixels into your screen to smooth out jagged edges. AA makes your game look better but eats up VRAM in your GPU and reduces performance so turning it off will give you more fps but edges that are seen at a distance may look jagged.

[Praesi]

Yes. Disable AA will increase the FPS alot.

[SkilledRebuilds]

Disabling AA only gives major performance back from MSAA/SSAA types.

FXAA/SMAA your not getting much back at all.

Depends on the type of AA used.

TXAA is an underwhelming end product, similar results to FXAA with three times the impact. Yes it is a mild improvement, but not worth the hit.

Rule of thumb: if a Funcom game (in this case, The Secret World) was the first game ever on the planet to use a rendering technique, it is shit.*

 

CSAA is still king of post-process AA performance economy, but literally nobody uses it anymore, which is annoying as hell.

 

*Not counting server-side technologies like the adaptive shadow mapping and server-side Nvidia PhysX first implemented in Age of Conan. These aren't really the same thing anyway, just thought I'd point that out.
