Describe the problem is not so easy for me: (sorry for my poor english).
At the start the program window appears correctly with its progress bar, but when the progress bar is complete, the window appears to hang.
or rather simply do not update!
In fact, if you now enter your account data (charName [tab] password [enter]) a seconds progress bar is show, which overwrite the first ,
and all the data objects are loaded into game(subtitle under progress bar)
After that the cursor changes shape according to the criteria of the game, but the window has never been updated!
in the avalilable log there are no errors ... or not explicit error
Perpetuum is working via Wine. GLSL need to be disabled and when the game is started, it flicker until video setting are changed (don't know why) but disabling vsync fix the issue.... and when you relaunch the game, enabling vsync fix the issue...
... and for r600g + wine add Dawn of War with addons Dark Crusade, Winter Assault and Left4Dead 1 + 2 and the Starcraft2 demo are garbage, Warcraft3 and FrozenThrone are silver at best with and without -opengl (where -opengl has good speed but bad graphics and without -opengl it is the other way round; it is not really playable).
Chromium BSU is platinum and Warzone 2100 and Scorched 3D look like platinum to me, dunno.
