FXAA???

Hi Guys,
Can someone explain to what FXAA is and if I should have it on or off?
Many thanks
Mark

 

Hi Mark. It's a low resource way of applying Anti-aliasing by softening/blurring the jagged edges without much stress on the GPU.

And it really works.....at blurring the WHOLE picture ! Dont use it !
Just my opinion

 

Thanks for the reply guys! Just getting my head around it!
Will see if it helps my pc or not.
Thanks again
