If you have an ancient PC, you may soon be ejected from Valve's wonderful world of warwizards. They have announced plans to strip Dota 2 of "support for some older systems and configurations", including 32-bit operating systems, saying it's so they can "keep the game and the Source 2 engine fresh". DirectX 9 and OpenGL are on the chopping block too (but Vulkan support will stand, obvs).
