I've got the game running with VorpX!
At first, I noticed the game also wouldn't run with flat screen. Not sure what changed. I reset the options.ini to default, set up the graphics for flat screen use using the in game menu, and then started a process of elimination in graphics settings after I found the game would run in VorpX after setting graphics to low. In the end, the only things I changed were setting shadows and effects details from "unlimited" to "high." I found the shadow setting significantly decreased load times, even just running flat screen. I wonder if the super long load time was making things time out?
I'm using a Reverb G2.
Shadows to high
Effect details to high
Instant Action works, single missions work, All the official maps work, several different aircraft including 3rd party modules all seem to work.
Making a custom resolution like 1920x1920, setting aspect ratio to 1.0, and modifying the default camera position in some aircraft's individual ini files to be farther away from the dash all seem to be beneficial in eliminating that "too zoomed in" feeling without playing around with a bunch of VorpX settings. For me, playing with VorpX settings to resolve that always resulted in fish eye vision near the edges of the screen.
I hope this works for you guys too.
