Owner

Longshot removed its WebGPU renderer (MagicBeanDev/Longshot#577) and the Linux AppImage's prebuilt renderer (MagicBeanDev/Longshot#574), and builds on CPUs without AVX2, but the launcher still passes WGPU_NATIVE, always passes LONGSHOT_VK_PREBUILT, and refuses a Linux PC without AVX2 ("The Linux AppImage requires AVX2").

What changed

Core/MakeGameCommand.cs: no WGPU_NATIVE on Windows. Older tools' build.py treats it as optional and builds without the WebGPU fallback when it is missing.
LONGSHOT_VK_PREBUILT: passed only when the tools carry lib/longshot_vk.so and neither DLSS nor FSR 4 is on. Current tools carry none and never read it (Longshot's tests/test_linux_preflight.py checks it is ignored), but AppImages before 2026-11-14 took the prebuilt renderer when it was set and may lack what compiling one needs, so it stays for them. Without the file it is removed from the environment, so a value in the player's shell isn't passed on. For takes a fileExists stand-in for the tests.
Core/SystemRequirements.cs: no AVX2 check (Evaluate loses its avx2 and linux parameters, which only that check used; no other callers in the launcher or Longshot). The string is removed from the 12 Core/Lang/*.json files.
Tests: tests/launcher_core/RequirementsChecks.cs and Program.cs follow; README updated.

Testing

Not compiled or run yet (the author runs no checks on their PC, and the lab machine has no .NET): python -I tests/test_launcher_core.py --strict --longshot <Longshot main> and scripts/translations.py's check are still to run. Things to look at first: the Evaluate signature change and the fileExists parameter.

Must be tested: the core checks on Linux and Windows; on Linux, a build of a current nightly without DLSS/FSR (compiles the renderer, as today) and, if one is still installable, a build of a release from before 2026-11-14 without DLSS/FSR (takes its prebuilt renderer).

Risks

A Linux PC without AVX2 now builds, as Longshot allows. Reverting the commit restores the old behaviour.

Longshot removed the WebGPU renderer and the Linux AppImage's prebuilt Vulkan
back end: current tools compile the back end in every build and read neither
WGPU_NATIVE nor LONGSHOT_VK_PREBUILT. The launcher no longer passes
WGPU_NATIVE, and passes LONGSHOT_VK_PREBUILT only when the tools carry
lib/longshot_vk.so (an AppImage from before 2026-11-14), so building those
versions without DLSS or FSR 4 works as before.

The requirements card no longer reports a Linux CPU without AVX2 as
incompatible: Longshot builds and runs on one, more slowly.
