Lock-in doesn't cause you to be able to 'squeeze performance' out of the hardware. It causes you to specialize your code to the platform so much you can't port it to another. It's the other way around. Developers don't care much about portability. The care about APIs that allow them to build performant programs. For them, a bad side effect of such APIs is vendor lock-in. Why would a game developer want to limit his audience? |

Let's assume GPU X supports some feature that GPU Y does not. Then you either use an (say OpenGL or Vulkan) extension to use it to squeeze out performance (lock-in) or you eschew the lock-in, don't use the feature and ignore the performance advantage. Now multiply this with lots of features and also consider that the graphic APIs of consoles offer some rather unique features that don't map directly to, say, DirectX11 or OpenGL.
