You might don't know that after all I played Ace Combat games mostly by my laptop's native Keyboard! xD
So here is an offscreen gameplay that show my hands playing the game with keyboard.
Soon I'll show my own keyboard settings on AC7 and even how to do Post-Stall Maneuvers with keyboard! :)
By the way, sorry for blurry auto focus, I know my phone's camera auto focus is sucks =(
All the settings is set to Low, resolution is 1280 x 720, no anti aliasing nor vertical sync, and resolution scaling 90%. FPS is 17-27 FPS, if there is lot of clouds, the framerate frequently dropped from 24 FPS to 19 FPS (without Fraps recording). Ground Attack or Base Assault mission is more costing performance since the battlefield is taking on the place where lot of objects rendered at once.
Also I'm using the steam version and the game is actually pretty optimized as long as you keep it all settings at low.
