Well... the configuration screen works just fine for me. There is a bit of a glitch in it when you go to the 3D section, but it doesn't prevent me from making the necessary changes.
Either way, I
think you might be able to change the resolution via the dangerouswaters.ini by changing the line that reads ".ModeID 1". I haven't actually tested this myself as the default resolution is good enough for me. But if there is a line in the .ini that corresponds to resolution that would have to be it. I would imagine that 1 signifies the default resolution. 2 would probably be the second resolution in the drop down menu on the 3D configuration screen. Etc, etc...
Man... I realized today that DW runs
really slow in VirtualBox. The whole interface lags like you wouldn't believe. And it's a bit unstable too. It locked up on me a few times when using time compression. I'm not sure I could play it like this.
Is it really slow/laggy for you too? Or is my computer just a dinosaur? I'd like to know how it runs/ran on your rig. Maybe I need more power again.
