I'm trying to get Gabriel Knight 3 working with dgvoodoo. Performance wise it is perfect, but it is way too dark. Any attempts to adjust this with the in-game gamma or the dgvoodoo brightness/contrast results in very washed out blotchy textures.

Is there a way to stop the wrapper from touching the colour/brightness? I tried the button that says it preserves the monitor colour profile but it doesn't seem to fix it.

See the attached to see what I mean.
