Heres the view with r_overbrightbits 1 and no gamma changing.

And what you have to do to increase the brightness level with r_overbrightbits 1;
Right click your sof2mp.exe -> Properties -> Compatibility
Something like this should come up (texts are in finnish but you should get the point);

Choose Windows XP to a compatibility mode and put 'x' to all the settings except the first one and click OK.
Then just open your sof again and you can change your gamma with overbrightbits on, enjoy the bright view.

I'm bored btw.
