According to Hans-Kristian Arntzen, a prominent open-source developer working on Vkd3d, a DirectX 12 to Vulkan translation layer, Starfield is not interacting properly with graphics card drivers.
To be even more direct: there's a huge overlap between the circles of "works in software dev" and "contributes to open source projects".
I really try to do different things at home than work, but I've definitely contributed fixes to game mods (why do so many modders fail to do null checks before trying to interact with short lived shit like projectiles?) and open source software I've needed to do stuff.
