Are they going to add a Vulkan or DX12 backend ?
Right now its OpenGL and if you have a fast PC, like 8700k + 1070, you ll be able to play some games at like 200-300 fps.
Naturally everything over 30 or 60 fps (depending on what the 3ds game runs at) is all you need.
So you dont really need vulkan or dx12 (for performance), as most pc's can run things fine.
Ive tested a few games with a G3258 (dual core, haswell pentium) overclocked to 4ghz, and so far havnt run into a game that doesnt run full speed.
