Dota 2 will drop support for some old hardware in the next few months, including the old 32-bit operating system.As part of them announcement Regarding the update leading to International 10, Valve stated that they are abandoning some of the old hardware that Dota supports so far. “In order to keep the game and the Source 2 engine fresh, we plan to remove support for some old systems and configurations. There are no changes today, but in the next few months, we will implement the following changes,” Valve said.
These changes include dropping support for Dota on 32-bit systems, macOS versions lower than 10.14, support for DirectX 9 to support DirectX 11, support for OpenGL to support Vulkan, and support for XAudio to support SDL Audio.
“Removing these old technologies will allow us to simplify our development work and use the new features of these APIs to provide a better Dota experience,” Valve said in a statement.
This may be a well-thought-out decision, because Valve can obtain a lot of information about common game equipment through Steam hardware surveys. Microsoft started to reduce sales of 32-bit Windows last year, but it still supports installations that have existed so far. In contrast, MacOS 10.14 was released in 2018.
