Blizzard has announced that support for older technology and operating systems will be dropped later this year for their popular MOBA, Heroes of the Storm.
The plug is being pulled on DirectX 9 support as well as support for 32-bit OSes. Once support ends, Heroes of the Storm will no longer run for players who are attempting to use the 32-bit game client or DirectX9. Please also note that while the 64-bit Heroes client might still be playable on some machines using DirectX10, this may not be the case for all configurations, which is why we recommend that all our players upgrade to at least DirectX11.
The switch will happen in July so there’s plenty of time to get upgraded to DX11 if needed. And let’s be honest, you should be using DirectX 11 at this point as the original DirectX 9 was released all the way back in 2002. And the fact of the matter is that even the most basic GPUs from the last several years include support for DirectX 11.
