Info:
I am running at 2560x1440.
Known bugs says:
Some cutscenes (with 4:3 mode disabled) contain overlays that don't have black bars.
But I see black bars on top of text
Minor thing: The stealth icon is stretched
I also tried starting up with everything being solid white until I had tabbed out and back in, but it might have been some command line settings as it seems to have gone away after I removed those.
Otherwise a very good job done. It runs a lot smoother than with the widescreen patch from wsgf/moddb
