Unable to Launch on Linux (Steam Flatpak)

[aasiegfried]

I realize official Linux support is probably tbd, but maybe this is an easy fix. Was able to play fine up to today on DX11 (needed the -dx11 launch option as Vulkan crashed instantly). Now both seem to crash, -dx11 just quits out instantly and vulkan will launch a window but give me a VK_ERROR_DEVICE_LOST popup and crash.

You can report this to the Proton thread on GitHub. You can also try the existing vm.max_map_count solution.

You can try:
* Playing fullscreen instead of windowed
* Enabling persistance mode on your graphics card (`sudo nvidia-smi -pm 1` note this doesn't survive a restart)
* Using proton-ge-custom instead of proton experimental
* vm.max_map_count as mentioned above
* verifying game files just in case
* updating graphics card drivers

I've been playing on Linux for a while now and don't experience crashes while actually playing, although I sometimes get a crash while watching a game.
