Can someone explain direct3d vs opengl?

[paulgt]

Which should I be using with an AMD r9 290?

Also, for anti aliasing with direct3d can someone explain the options to me? I dont know what it means by the amount of samples and quality. I'm used to 2x 4x etc.

On AMD hardware, Dolphin runs faster on the D3D backend than the OpenGL one, so you want to use that except for specific games that don't work right in D3D.

As for the AA settings, at some point one of the devs hooked up the dropdown to the full range of options the DirectX API offered for Anti Aliasing. I'm not sure anyone's posted an explanation of the differences between all the options yet.

I don't know...opengl is faster and gets less hiccups than d3d with my r9 290 in mario galaxy, zelda wind waker, metroid prime and ikaruga (and I have a i7 4770).


Also I find opengl looking better than d3d with everything maxed out, d3d looking jaggier. Both kirby return to dreamland and epic yarn run almost flawlessly with both backends even with LLE audio here but there is an annoying black shadow using opengl in kirby return to dreamland so this is the only game I play with d3d instead of opengl.

I'm mainly trying to get xenoblade working. D3d, for some reason, has worked better on it for me.
