Created attachment 58424 [details] lutris-wine-2.10.output
Patched wine2.10 from Lutris works with the following output attached.
I have the same problem. Witcher 3 game does not start. Wine-Staging 2.10, Arch Linux x86_64, AMD Radeon HD7770, Mesa 17.1.2, Linux 4.11.6. Unfortunately, I do not have the authority to attach my console output.
