dhewm3 VS magnum-examples

The installation is different from what you might be used to from your typical mod. Download dhewm3_1.5.2_win32.zip from the githup page, unzip it, then copy, as instructed by the WHAT_TO_DO.txt files in the base and d3xp directories of the unzipped mod the .pk4 files from the game directory over (d3xp is only there if you installed the Resurrection of Evil add-on first). You can then uninstall the game from Steam.

There is a source port of Doom 3 if you want to play it on Linux or macOS.

Why do you want to run old, buggy code through wine when you could use native dhewm3 to play the original (non-BFG) version of doom3 with Bugfixes, OpenAL audio and proper widescreen support? https://dhewm3.org/

BFG has better out of the box support, but both versions are open source and as such the community has made source ports for both of them to the point they are essentially equivalent and you only pick the one with the features you want the most, last time I played was using BFG because RBDOOM3 added support for PBR so the game isn't so absurdly dark but your mileage may vary and may prefer dhewm3's more faithful experience using the original release

However, it seems that LibreCoop works with dhewm3 that has a fork that supports gamepads.

u/d10sfan has added dhewm3 source port for Doom 3 demo, ioquake3 source port for Quake III Arena demo and Zandronum source port for RetroNinjaCyberAssassin to Luxtorpeda repo. Thanks to that, native Linux versions of the games can be played as Steam games.

The games you mentioned, UT99, Quake 4 and Doom 3 should run just fine with OpenGL though (If you aren't already, use the dhewm3 source port of DOOM 3!). Consider using the Windows version of UT99 through Wine though, that might save you some headaches.

While the Vulkan wrapper layer isn't that well documented or advertised yet (to Magnum standards at least), there's a Vulkan Triangle example making use of the basic bits to get you an idea how it might feel like. Apart from that:
