You can modify the textures the same way you would paint a 'craft (check the paint section in the forums or google it up) but payware aircrafts usually come with bumps and highquality cockpits. There are a bunch of things but only if you turn your settings down for the cockpit quality and maybe fool around trying to delete some of the bump map texture files. I'm no expert in this but I have plenty of payware aircraft that hit FPS. On the "Aerosoft Bush Hawk XP @ Alpnach" I would try to modify it. The rest, suck up the 20 fps and save some time
