caused the whole world to suffer
In addition to what others have already said, this line in particular is complete bullshit. The vast majority of the world doesn't care about Ukraine in any way beyond "war is bad," and indeed a large chunk of the global south has expressed that the war is entirely the West's fault for provoking Russia constantly since the collapse of the USSR. The only people suffering from the war are in Ukraine, Russia, or any of a number of European nations that were strong-armed into shutting off their access to Russian fossil fuels by the US so American oil companies could dominate the energy markets in that region of the world at the expense of workers who saw their utility bills go up 4x overnight.


Games have to talk to your operating system to have it tell your GPU to draw lots of funny pictures that come together to make up the graphical portions of the game. Game developers do not want to do this directly, because talking directly to the OS is hard. As such, games talk to graphical APIs like Vulkan or DirectX to do the hard bit for them.
For years almost all games used DirectX, which is made by Microsoft. This gave Windows a virtual monopoly on PC gaming because they weren't about to let their competitors use their API. Then Vulkan came out, which was designed from the beginning to be OS-agnostic, sending us to the promised land of games that could (with some other efforts) run on any machine, anywhere.
