From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Yes, directx to opengl (included in WINE) was used exclusively for a very long time before dxvk and vk-d3d came out just a few years ago. for older games you should be good to go, before i had a vulkan-capable card i ran all kinds of older games, usually without having to tweak anything. in a few games i had to change a game setting to use D3D9 instead of 11.
Do you remember what the module was called as any directx game defaults to using the igpu for dxvk and there seems to be no option(in lutris) other than to outright disable dxvk.
That's exactly what you want. DXVK is the "new" DirectX to Vulkan translation layer (that's where the name comes from), and if you disable it you will be using the DirectX translation layer from Wine which uses OpenGL
Disabling DXVK is the way to do it in Lutris. It's in the Runner Options tab for the game settings. If you create a new Wineprefix using
WINEPREFIX=~/.local/share/wineprefixes/newprefix wineboot, it will use WineD3D (the D3D➜OpenGL converter) by default. It's what Wine uses for all Direct3D APIs up to Direct3D 11. DXVK is a completely separate project to Wine, but Lutris and Proton bundle it and use it by default. Lutris is completely usable without Vulkan, despite the scary warning.I never figured out how to disable DXVK so eventually I just made a 2nd wine prefix without DXVK for games I run in OpenGL.
However if your GPU doesn't even support Vulkan then you shouldn't be using DXVK at all so why would you not want to disable dxvk?
hmm, not sure… i've heard it referred to as "wined3d"? when i had a non-vulkan card it usually wouldn't try to run vulkan so i didn't have to mess with it. what result does disabling dxvk have?
in steam you can put
PROTON_USE_WINED3D=1in the launch options, but this doesn't help for non-steam games
