Celeste - CommandMC/EpicLinux GitHub Wiki

Celeste requires a simple start parameter / environment variable set, since the default graphics driver (D3D11) does not work properly.
Add one of the following code snippets to your Legendary config file:

[Salt]
start_params = /gldevice:OpenGL

or

[Salt.env]
FNA3D_FORCE_DRIVER = OpenGL

Note: Although the Vulkan driver appears to work at first glance, it crashes after entering a level and waiting a bit
