Gave a quick read through yesterday. Very nice read. AA quality better than 2x and close to 4x (sometimes better sometimes not). Looks to be superior to MLAA implementations too. Check out Tim's Lottes blog for more in depth info.

Looks cool, really cool, although I didn't quite catch, if it's necessary to code this into the game itself or if it will also be a feature in the CP.

winton · 07-19-11, 11:16 AM

I believe the developer has to implement this into the game.

hirantha · 07-19-11, 11:25 AM

Yeah they said the developer has to impliment it, but hey nvidia made the PC gaming proud again! Well done!!

Yea that's the biggest catch. It's better than MLAA performanise wise because it's tied directly into the game. MLAA is still a good option for anything that doesn't use FXAA. It would be nice still for nvidia to be able to use MLAA, but that wouldn't make a lot of marketing sense because then there would be less incentive to use FXAA.

I don't think so:

Then FXAA will be available in the Nvidia Control Panel. But FXAA currently works only in OpenGL.

Description of FXAA from Control Panel -- from JackFuste:

Antialiasing - FXAA

FXAA is a fast shader-based post-processing technique that can be applied to any program, including those which do not support other forms of hardware-based antialiasing. FXAA can be used in conjunction with other antialiasing settings to improve overall image quality. Note that enabling this setting globally may affect all programs rendered on the GPU, including video players and the Windows desktop.

• Turn FXAA on to improve image quality with a lesser performance impact than other antialiasing settings.

• Turn FXAA off if you notice artifacts or dithering around the edges of objects, particularly around text.

That's awesome, if it really is going to be available globally. Can't wait for a proper release.

Just tried it with Duke,seems to work well,didnt notice any hit really.

Good read.

One can only hope this new method is implemented on the next gen consoles, that way all games will have it implemented.

Otherwise only way to see this is for NVidia to pay dev's to use it.

Blakhart · 07-23-11, 01:07 PM

Testing fxaa right now.

walterman · 07-24-11, 11:58 AM

Again, this is a post processing technique, it does not add any color information to the scene, just depth info, and a shader that does a sort of conditional blur with the pixel color & the surrounding z information.

In real games like the MMO AoC, this FXAA makes the game ultra blurry compared to the hardware FSAA methods.

This FXAA is only good for games that does not support hardware FSAA, or with performance problems.

If you want max IQ & sharpness, SSAA is the best & compatible with all the rendering techniques. But ofc, the slowest.
