# render-backend-forced-unavailable

> Talos next · Since 0.6

the project forces a graphics backend (`render.backend` `"vulkan"` or `"dx12"`) that cannot start on this machine (no adapter on it, or DirectX 12 off Windows); the game stops rather than fall back. Code pending coordinator confirmation (default allocation, lane plat-gfxbackend)

## Meaning

the project forces a graphics backend (`render.backend` `"vulkan"` or `"dx12"`) that cannot start on this machine (no adapter on it, or DirectX 12 off Windows); the game stops rather than fall back. Code pending coordinator confirmation (default allocation, lane plat-gfxbackend)

## Fix

set `render.backend` to `"auto"` to let the engine choose, install a driver for the forced API, or override with `WGPU_BACKEND` for one run
