Dolphin, the GameCube and Wii emulator - Forums

DX11 has a lot less glitches in games for me - Eternal Darkness, TMNT, Mario Golf, Ghostbusters and on and on. What games work better on DX9? It's only a little bit faster but if you have a good CPU, that doesn't matter. DX11 for the win!!

It depends on both the game and your GPU. The d3d11 backend does not run as well on older nvidia and ati gpus.
