Selected Test Results (selected in 'Test Results' table below)
What works
about everything tested. no directx10, but everything else. incredible smoth and stable, not a single crash in over 250h gameplay.
campaign and two szenarios could be completed, so there should be no reason to crash somewhere else.
What does not
direktx10 (can be deactivated, look at howto)
What was not tested
multiplayer;
the best graphical settings (graca too slow)
Additional Comments
well, it works extremly good. with patch 1.2 there is no longer a need for a patch, editing the Engine.ini is really the only thing you have to do.
speed is quite nice, too, no lags on a nvidia 9600GT with medium settings and 1920x1200 resolution (excpet ultra-large cities ofc) - i assume without testing it that it isnt muach slower as a comparable windows system.
did i already mention that it didnt crash for 250h gameplay =) ? hard to find, such games, nowadays.
