Oa and dayz implementation is that fxaa automatically uses sharpen filter while smaa not, thus the smaa and also noppaa looks less sharp than fxaa this was corrected in arma 3 since update 1. Difference between msaa and fsaa pcmaclinux society. Efficiently moving antialiasing from the gpu to the cpu pdf 1. Evaluation of antialiasing techniques on mobile devices. Fxaa will also vary significantly between games, as its a developer implemented shader program, so as forceman said, its very subjective. Because of that, they are significantly cheaper, but less accurate and may soften image if they misdetect edges location and filter a non edge surface. The performance impact with it at smaa 1x is higher than fxaa, but less than 2x msaa.

Fxaa is designed to be easy to integrate into a single pixel shader and it runs as a singlepass filter on a singlesample color image.
Nvidias fxaa can now be used on almost any game with great results, both on image quality and performance. Smaa should be in everything as it is light and free software, you can even inject it into games that dont have it natively as it is a post process filter like fxaa but it actually works unlike fxaa. I personally find smaa to be a great aa alternative vs. Fxaa is not designed to replace msaa csaa or any other hardware aa method, but rather just offer another option.

As harry said, 8x msaa is almost perfect already so i dont think youd need to combine it with txaa eighter. Do some tests to see if you can run msaa at decent speeds. On newer gpus and in newer games it is the exact opposite with fxaa being nearly free and msaa being the killer. I really have not been able to figure out which is best all i know is that my 690s do not have enough vram to do 8xmsaa at 2560x1440.

The change device interface can be used to select msaa modes to mix fxaa and msaa. Multisample antialiasing msaa improves image quality by taking the specified number of samples to determine the coverage of rendered pixels and blend them to form the rendered image.

Id go with fxaa if you get solid frames with it, but otherwise just stay with fsaa. Even 4xmsaa might not be practical for example with larger fp16 precision g. Performing msaa becomes more costly when there is an alpha blended edge, resulting in the graphics core marking the pixels on the edge to on edge blend. It was explicitly designed to give game developers the ability to implement a more cinematic feeling to a title and is designed to improve on msaa s rendering without the. It operates similarly to supersampling in that it upsamples the original image, generating two samples per pixel, but instead of obtaining a separate color value for each subsample, it instead reuses subsamples from neighboring pixels to attain higher quality but with less.
