First off, why, oh why are you running three versions of Falcon? I would suggest copying them as backup, then delete your installs, and do a clean install of 4.33.3 You should able to run Falcon BMS 4.33.3 in Win7/8/8.1/10 64bit with no issues and no compatibility mode needed.
Second, no matter what you do, BMS will go to a lower resolution of 1024x768 when in the 2D menu screens. This is hardcoded in the game and even if it can be fixed, none of the devs have done so yet. When playing in windowed mode, you will see BMS as a small window on the upper left of your screen… or go to your falcon bms.cfg file and set **set g_bCenterUI to 1 and the small window will appear on the center of your screen. When playing in fullscreen mode, the 2D menu screens will fill your entire monitor, but it does this by forcing your monitor to go down to 1024x768 resolution. Don’t worry about it, the game will go to whatever resolution you set (5896x1080 in my case) once you’re on the 3D world.
@DragonHunter:
I use a wireless keyboard and a wireless mouse to play Falcon BMS. I have never used a Joystick before.
Kudos to you for playing BMS with a KB/M setup…. but the biggest favor you can do for yourself is to get a joystick or even better, a HOTAS. Have you ever driven a car using your TV remote? Or played Tekken using a Rockband guitar controller? While both are possible, it’s a much easier and more enjoyable experience when doing the relevant activity with the right controller (steering wheel + pedals, PS4 controller).**
