Sorry, I made a little mistake here. With the settings published above I get 18-20 fps WITH THE 757 professional. With the same settings, but HDR dissabled I get 30 steady fps in the 757. However, with the saab I get 15 fps with HDR and 18 without HDR. Why this little plane is heavier on fps that the 757 professiona?. I even tried with the flyjsim 727 and I get WAY better performance... I can only think it must be the back passenger cabin what is making this plane so heavy on fps (hope there is a way to remove it), or something beyond my understanding.. As aditional information. I had to lower de rendering distance to low, texture resolution to normal, disable all "things to draw" and "special effects" to achieve steady 23 fps with this plane... That is excesive
