Environment Variables?

[Saroufim]

I suggest adding a section in the configs for some predefined environment variables. These can be useful for both native and wine-based games. Check a few of them here: https://github.com/lutris/lutris/wiki/Performance-Tweaks

Added as Wine/Proton option for next release.

Has this been added to the dev branch or the master branch? I'm using 0.12 and I can't find the feature.

[tkashkin]

@Saroufim yes, it should be available in 0.12. I assume you can't find it due to #132.

[Saroufim]

The fields don't show up with Proton either

[tkashkin]

Weird. It should appear for both Proton and Wine.

Options are shown only in run dialog. Open it from context menu.

Hi,

I use Nvidia PRIME render offloading on a game by game basis. In steam I just need to add the prefix to %command%. In GameHub I can't seem to find a easy way of adding environment variables to the game. I looked at enabling the compatibility options, but it doesn't seem intuitive.

I'd like to apply the environment variable on native games as well as compatibility layer games.

For reference I use the following for OpenGL Games:
__NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 __GLX_VENDOR_LIBRARY_NAME=nvidia

A good solution might be to add an Environment box to the UI, similar to the parameters one?

Thoughts?

@HuxyUK #297 (comment). Something like this should probably work:

env __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 __GLX_VENDOR_LIBRARY_NAME=nvidia ${command}

[HuxyUK]

Thanks the for the quick reply!

Where would I use that command? Can I add it using the UI or do I need to write a compatibility script? Adding it solely to the Executable or Arguments doesn't work, so I guess I'm missing something.. 😕

[tkashkin]

@HuxyUK you should just add it to the Arguments field.

It hasn't been merged in master branch yet, so you need to be on dev branch for it to work. Check your version in Settings or with com.github.tkashkin.gamehub -v in terminal.

[HuxyUK]

Ahh right!
I'm on the master branch packaged in Solus at the moment. Explains why I can't get it to work.

Branch:  master

@HuxyUK as a workaround for older versions you can try this:

Executable:

/usr/bin/env

Arguments:

__NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 __GLX_VENDOR_LIBRARY_NAME=nvidia /path/to/game/executable

[HuxyUK]

I tried what you suggested but every time I set /usr/bin/env in the executable field it ends up resetting it back to the game's startup executable. It's very odd behaviour.
