Just wanted to let you all know the SP-AKI single player Tarkov mod works on Linux. There’s a bit to do to get it running as the client has registry checks to ensure you own a legitimate copy of the game so what you need to do is export your registry keys (LOCAL_MACHINE /Software/Wow6432Node/Microsoft/Windows/Uninstall/EscapeFromTarkov) then create a shortcut (lowercase d: or whatever) in dosdevices to your legit install and then import the registry keys into your wine prefix using wines regedit so it will pass the checks on the uninstall exe and battleeye dll.
In addition you need vcrun2013, vcrun2019, corefonts, .Net 5.0, d9vk (this uses windows directx runtimes which were recently removed from the microsoft site, until winetricks fixes it you can just download manually and copy to .cache/winetricks) and obviously dxvk.
By default the server provided by SP-AKI tries to run https for port 443, in the server.js config files simply change this to something above 1024 (1443) and in the launcher create a new default server with url https://127.0.0.1:1443
There you have it, Tarkov in SP. No lag, no desync, dead scavs on Linux
