Hello.I using fs2004 with CH virtual pilot and pro pedals (game port), yesterday I bought CH flight sim yoke (USB) and pro pedals (USB), and I have little problem:When I sturtup the simulator, all OK I got the normal frame rate that I used to... but after 30min of flight (spicial with VATSIM) the FPS drop by 50% and eerytime I push the rudder or brakes the PFS drop by 75%!!! and back to 50% drop.I tried to fix tish bug with the solution of autogen bug... but this is not the problem, also I tried to bun a ney USB2 ports and nothing...maybe USB increas the normal memory leak of this simulator?I use:P4 2G 512K RAMGforce 2 grafic cardWINXPThanks alotTomer

Hello TomerI use CH throttle, peddle and yoke in FS 2004. I have not had any problems with FPS drops. I also run them thru an external USB 2.0 hub. If useing USB 2.0 mike sure you're useing the correct MS driver. From experiance before if the wrong driver is used you get an intermittent delay or erattic operation useing USB devices.Bill M

Usually, you will get performance problems using the Gameport version of a controller rather than the USB version. I run the Flight Sim Yoke and Pro Pedals (Both USB) and experience no performance problems when turning or otherwise using the controllers.If you are no longer using the gameport on your computer, consider disabling it... either in the BIOS of your system or at the driver level. Perhaps the computer is still polling that port for information when it should be concentrating on the USB port.Also, if you have switched to the USB controllers, be sure that any entries for the Gameport versions are no longer there. Interesting problem...-Greg

Suggestion: delete your fs9.cfg file and let FS9 re-create it. Perhaps the entries for your gameport controllers are causing issues of some kind. (Note, though, that if you delete this file a bunch of stuff will revert back to default values. If you're reasonably good at hacking .cfg files, back up your current one and then add your customized entries (NOT including the entries for your gameport controllers!) back in to the new one that FS9 creates at start-up when it does not find a valid one.I switched over from gameport CH stuff to the same ones in USB form a while back, and haven't had any performance issues that are related to those devices.good luck,Dave Blevins
