@Ralph i have found this problem in Dishonored.
I set Dishonored to a 1920 X 1440 resolution in dishonored graphics settings.
If i start in vorpx the settings shown at the launch screen of vorpx is 881 X 661.
It doesnt matter what i change in Dishonored engine.ini the resolution does not change in voprx .
could that becaused by adding the launchcomand in steam ” -windowed”
(Othergames can be set to windowed and still have the resolution set to 4k and the resolution configuered in the games ini. will show in vorpx though)
