Wine-staging 2.0 log of diablo3 running the d3d11 x64 client.

Since the release wine-staging 2.0, diablo 3 is able to start in the 64bit
mode, which utilizes d3d11 for rendering (Thanks!).

It is not without issues, yet, though.

Namely, the performance is really bad, on my machine (core i5, GTX 770) it
renders about 3 frames per second (whereas the 32bit version runs with >60
FPS). The rendering is not without issues, too. Characters look matte and dark,
very different look from the one one sees in the 32bit client.

I am attaching a log from my machine (Arch linux, 64bit, nvidia blob 375.26,
wine-staging 2.0).
