The Witcher

What works

Game works at decent speed, but a bit slower than on Windows 7. I played up to Wyzima's outskirts (and few moinutes on swamp, from loaded save) and everything went fine except issues described below.

What does not

Health, toxicity and experience bars aren't displayed. Enemy's life ring isn't displayed too. Mana bar is visible, but won't move, only changes colours.

Some minor artifacts in game menu exists. (And in-game 2d elements like map.)

Sometimes a weird error happens. For more info see bug 12771, especially comment 32. "Absence of character/monster model. No characters are visible, only their armor/eyes/teeth, rest of the body is transparent." Restarting the game usually helps, but not always.

Sound is lagging and echoing (this makes it hard to recognize words). I don't know if it's fault of Wine or PulseAudio.

You can't run game using its launcher. You have to navigate to ~/.wine/drive_c/Program Files/Wiedźmin/System and run witcher.exe.

Additional Comments

CPU: 1 core (seriously, 1 core due to ACPI bug), 4 GHz GPU: GeForce 560, closed Nvidia driver RAM: 8 GB DISK: SSD Also when I pressed alt+arrows, game was losing focus, but this was due to Gnome Shell. I installed polish premiere version (1.0), (it won't run due to lack of wine admin rights) then installed all updates up to 1.5 and all is OK, except issues described above.

If you are hit by bug #34052 (invisible character models), or flickering, set this key in the registry as a workaround (it happens on closed Nvidia driver, and to some on Mesa / Intel. It didn't happen to me with Mesa / radeonsi):

[HKEY_CURRENT_USER\Software\Wine\Direct3D]
CheckFloatConstants="enabled"

Another similar issue is bug #46553 when some textures turn black indoors. For now, install  d3dx9_35 native override to work around that.
