Re: [PATCH v2 0/2] MR6301: Introduce a new WINE_VIDEO_DRIVER variable.

[Rémi Bernon (＠rbernon)]

I don't think this can work, an environment variable is inherently a per-process setting and the graphics driver needs to be the same for the entire prefix (or at least for a given desktop).

Wine doesn't restrict how prefix are started and it would be up to downstream wrappers to change the prefix driver when starting it, based on an environment variable if they want and only allow prefixes to be started with the main process.
