Hello,I have three MD80 sims: The F1 Super 80, MDMAX and the LAGO MADDOG. The MDMAX only has a 2D cockpit. The other two have both 2D and VC selections from the A/C selection menu.If I select the 2D only systems, my FPS is about the same for all - about 20 at modest airports (scenery). The F1 Super 80 runs its 2D and VC at about the same rates - 17fps. The MADDOG is different. This is where my question starts:The 2D MADDOG runs at about 17fps. IF I select the 2D/VC model, the FPS is at about 16FPS in the 2D. But once I select the VC, the FPS drops to about 4. I cannot now return to the 2D and get the higher FPS rate again. It is now "stuck" at the VC rate of about 4.This is by no way a complaint - I would like to know if there is a reason for the 2D->VC->2D FPS drop and perhaps a reason why it does not return to the higher rate when I go back to the 2D cockpit.Thanks in advance,Ron SagelNEAR KCHS

Try a little experiment. I don't know if it has something to do with it or not. In your Options-Display menu you will find a tab for Aircraft. In that section is a tab for quality (???), I'm at work I can't remember. Anyway when using only a 2D panel slide it to the left as that has to do with the quality of the VC visuals. It takes up memory when on, even if not being used.Lee

Hello,Thank you for the help - that is the answer!I tested this with ALL of my addons. When I set the VC gauge quality to LOW, the FPS are pegged at the top of my selection (now 25fps). I have a rather high end system and display card(s) in SLI mode and have never had great results until now. Obviously, some addons work with the HIGH quality setting but I must say now, the MADDOG VC looks great at low quality (so long as you fly during daytime).Thanks again and cheers,Ron Sagel
