HelloFirstly, the NGX is awesome! However, i am experiencing intermittent frame rate drops when i use control inputs via either the rudder pedals or joystick. For example, i will be flying at altitude or taxing at the airport and if i use the rudder or ailerons to make a control input my frame rates drop at tmes up to 50%. I flew handheld into KLAX with the 2D panel the other day and it dropped to nearly 5fps at some points! I never had this problem previously with the NGX so it seems to be recent for some reason. The same approach was flown with the level-d and it they remained in the upper 20's under the same conditions! The only association i can make is the the frame rates drops considerably in some places when i try to manually fly the plane. I do use ASE and EFB so i thought it may be a simconnect issue impacting frame rates but the problems are the same even with the EFB off. I re-installed and again i still had the same issue. Could it be a USB power issue even if other aircraft do not have problem? I am just wondering if anyone else has had a similar problem? The NGX is beyond awesome but i'm kinda stuck as to why i am experiencing this issue. Any suggestion woud be greatly appreciated!thanks allMatt Thierens

System specs? Also, what type of USB (2.0, 3.0?) do you have? How many USB ports and what type and how many controllers, and how long are the cables from the computer to the controllers (latter is probably not an issue). Are you using a USN Hub with or without it's own power supply?Looking forward to helping you resolve this.

I have an i7 920 2.67ghz with a G-Force 285. I have 8gb of memory too. Its a pretty good spec. In terms of usb i have them plugged into the rear of the computer into the motherboards USB. I tried to unplug and re-plug but still the same story. I'm trying to backtrack in terms of whether i have updated any software etc but nothing springs to mind. I did update microsoft security essentials so maybe that might have something to do with it? Just seems weird that i would experience a frame rate drop when using the joystick or pedals. Thanks for your helpand its USB 2.0
