Its weird as I get 40+ fps with the cub but hardly over 12 with this one.
Edit - sorry - i should say in all fairness that despite a very jittery flight i do think that the model is fantasic both inside and out - just a shame i cant fly it in full daylight.
Would you care to post your system specs? FSX can handle a massive ammount of polygons. Its a poly crunching animal, but the texture size may limit its useability on some video cards. If you have an older video card or low memory, you may want to lower the texture size to 2048 on both external textures. Some video cards have a hard time processing the 4096 textures we used. The cockpit still uses 2048's.
