SkillerShadow: At least I have been discussing ( for one email ) with the customer support at GoG and they suggested the basic debug options; and I also did my own testing with different configurations:
DX Wrapper options to:
Display mode - same as desktop (default) // set by application // 1920x1080 60 Hz.
Scaling method - Screen fit (default) and Integer scaling.
* Note about scaling method - I have combined this with editing the scaling from Nvidia Control Panel as well Nvidia Control Panel -> Adjust desktop size and position -> Scaling -> and I went through all options - Aspect Ratio, Full-Screen, No scaling, Integer Scaling -- and even enabled "Override the scaling mode set by games and programs".
Outside of the DX Wrapper, I also tried with G-Sync enabled and disabled as well.
In SFC.ini - I have also changed the [Mouse] configuration from async = 1 to 0 and back.
I have done all of my testing with a single monitor enabled at 1920x1080 running at 60Hz.
Unfortunately the only viable workaround is to press "D" in-game to remove the side UI and then switch around to access it.
Late last night I tried with the other monitor unplugged as well and no luck.
The best thing to come out of this is that I learned how to setup up a virtual machine with Windows XP :D
As well, if you are in combat and press Esc quickly a few times, you'll be able to notice that the ships are actually less wide in that screen than the "normal" view.
Yeah, I've noticed that too.
Unfortunately, not having the control panel makes the game difficult to play. And I actually know most of the key binds by heart for this series!
