[Request] Option for Discrete GPU per program

[VarLad]

Is your feature request related to a problem? Please describe.
I've a bottle for a bunch of Indie Games I have. Some of them require a Discrete GPU to work, while most perform well with the iGPU.

Describe the solution you'd like
It would be nice if one could select Discrete GPU for per program added. Every program could have a "Use Discrete GPU" option with 3 options, namely "Yes", "No", "Follow Global Settings"

We're going to do this by default with the Layered environment, where the settings are no longer per bottle but per program instead. I think it is possible to take it to all the other envs too without too many complications.

@mirkobrombin Sorry to use this issue to ask a question
GE-Proton comes with its own DXVK and VKD3D right?
When I use it in Bottles, are the DXVK and VKD3D being used are the one by GE-Proton or the one by Bottles?

[mirkobrombin]

Bottles don’t use the one coming with proton. Also please consider reading this bottlesdevs/components#145

[VarLad]

@mirkobrombin I just noticed, Wine-GE also provides its own vkd3d-proton.
Can Bottles use that?

[mirkobrombin]

Just keep vkd3d disabled in bottles should do the trick. Btw it’s the same, “our” version, the lutris one, the GE one, etc are the same version

[VarLad]

@mirkobrombin Disabling vkd3d just crashes the game for me on Wine-GE-7-11
Also, doesn't Wine-GE often update vkd3d-proton to the latest git?
"Ours" is comparatively older right?

[mirkobrombin]

The bottles one should be the latest available, I don’t think GE uses the latest commit 🤔

[VarLad]

@mirkobrombin Sorry for the late reply. Not every version, but in some versions I spot this:
https://github.com/GloriousEggroll/wine-ge-custom/releases/tag/GE-Proton7-17

dxvk updated to latest git
vkd3d-proton updated to latest git
gstreamer libraries updated

So I assumed it provided the git versions of dxvk and vkd3d

[mirkobrombin]

It’s weird but may be possible

[VarLad]

@mirkobrombin Is it feasible to actually use the versions provided by Wine-GE?
It would be nice if I could do that
If yes, should I open a Feature Request issue for this?

[mirkobrombin]

This mean alter Bottles for just 1 runner, sounds something possible but maybe too much effort. As a workaround, make a new bottle without turning on dxvk, then close and set it to enabled in bottle.yml

[VarLad]

@mirkobrombin Trying that but the game refuses to run that way.
I'd reckon its because of the deps.

Also, it'd be nice if Wine-GE could provide an option to use its own VKD3D since VKD3D keeps adding compatibility for new games and generally moves fast, but has a bi-yearly release, which is bad for playing some games.

[mirkobrombin]

With 2022.7.14 we will distribute our new runner based on Proton so you may want try it instead

[VarLad]

@mirkobrombin Would that runner provide git build of VKD3D?

[mirkobrombin]

No
