Hi all,
I'm getting curious about the llvm/clang profile, and how does it fare for games. I was wondering :
- does wine work well with modern (64 bits) games such as Cyberpunk2077, Witcher 3 nextgen, etc... ?
- does it work well with older (32 bits) games ? Like the first Deus Ex, Thief 1 & 2, etc... ?
- what about Linux native games ? For example, Necrodancer is linked to libstdc++.so.6, libgcc_s.so.1 and others. Would the game work on a llvm profile using musl and libc++ instead of glibc ?

Code:
krumpf@fractal /mnt/games/Crypt of the NecroDancer/game/NecroDancer64
$ file NecroDancer.x64

Yes; CP2077 is "under optimised" in any environment, wine actually helps to mitigate this. Whislt I get lower (like under 80) FPS in Gentoo through wine with CP2077, it's a smoother experience with more predictable frametimes - a plus in my book.

I don't have a huge variety of 32bit games to test with, and steam shits the bed if you let it "background" compile the vulkan shader cache for 32bit games, but aside from that they work.

I don't know about llvm, but there comes a point at which trying to maintain a "static system" for native becomes more of a chore than losing a few fps and just letting them run through an ancient version of proton/wine - it's much easier to keep them around than an old glibc. I recently just ticked the box for "run via steam play" on my Tomb Raider back catalogue, because the Feral Interactive native versions no longer "work OotB" like they used to.

I think llvm/musl is going to very much be a "suck it and see" situation, sorry, but technically if you can recompile wine/proton in that environment then they should "just work".

my system is almost llvm compiled and some llvm release in the past caused major issues with STEAM games. unfortunate but it is why started using flatpak since it resolves this conflict
