A prominent open-source dev publishes their findings as to what's going on with Starfield's performance, and it's pretty darn strange.

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.

    Looks like Hans implemented a workaround in vkd3d-proton 2.10, using the open-source AMD vulkan driver on linux (RADV).

    Device generated commands for compute

    With NV_device_generated_commands_compute we can efficiently implement Starfield’s use of ExecuteIndirect which hammers multi-dispatch COMPUTE + root parameter changes. Previously, we would rely on a very slow workaround.

    NOTE: This feature is currently only enabled on RADV due to driver issues.

    I don’t imagine it will take long for this to make its way into a Proton experimental release. Folks with AMD graphics who are comfortable with linux might want to give it a try.
