Pity that Khronos never got the support they needed to make cross-platform raster APIs a reality. I mean really, what an
enormous and
crying shame that a successor to a highly-demanded API like OpenGL never emerged. It's really quite sad that users never had a corporate champion to resist the allure of a proprietary graphics API. The stage was set for every modern OS to be unified under a new raster library, but the setting was dashed for a petty buck. Quite a tragedy.
Ah well, it's funny to see people complaining because it really solos out the OS you're using. Windows users have native DirectX, Linux users have near-flawless DXVK, and Mac users... well, Mac users get what Apple gives them, and they have to learn to be happy with it.
