OpenGL is good enough and works on everything. Additional performance is probably not relevant, I mean my mediocre mobile GPU is always in it's low power state of 200 mhz and with very low GPU usage when running anything in rpcs3.
If someone decides to work on Mantle or whatever, it is certainly not for performance reasons, but because it could make development easier.
