Just tried the PC Demo and can't even finish the first objective.Trying to control the jet pack fly mode for me is not Challenging its just plain Aggravating!Capcom won't get my money for this piece of crap!
I found the answer.Don't even try to fly with the mouse with this game.Use the 360 controller for the pc.It's still hard to shoot when flying but you can maneuver much easier.When you land its easier to use the wasd keys to get around and the mouse buttons to shoot.With a trainer with unlimited health,unlimited ammo,no reload and one hit kill this game will be bareable.
the 360 controller worked like a charm for me, an steady 60fps at 1080p all maxed out, the game looks pretty good.
I tried adjusting the mouse slider it helps but no mouse setting comes close to being as easy as using the 360 controller for flying!
