HiHope someone can helpConstant Lockups on landing, have tried suggested fixes ie deleting config file & saved situations, starting in the Cessna first,turning off the weatherDownloaded the 800/900 hoping this would fix itMy System Asus P4C800,P4/3.0,ATI Radeon 9600,1MB RamThanksValkyrie

It sounds more like a computer problem than the PMDG product. If you can, check your CPU temperatures (look in the BIOS or download a hardware temperature program) and reply back with the results. Also make sure you're not overclocking your CPU.Nick B.http://www.precisionmanuals.com/images/forum/800driver.jpg--AMD Athlon XP 3200+ @ 2.25 Ghz (405 mhz FSB)Soyo VIA KT600 Dragon PlusnVidia GeForce FX 5200 128 mb2 x 512 PC400100 GB Western DigitalMicrosoft Sidewinder Precision 2

Thanks for your reply NickMy CPU has a variable speed fan that keeps the temp constantEverthing is ok till you touch down then it stops then starts all the time(stutters)It will do this after a long or a short time period

Oh ok, I thought you mean't your computer just turned off which is usually meant by crashing. Before touching down, look at your framerates and respond back. Also try to land with clear weather or decrease the detailed cloud percent (if you use detailed clouds) since that's usually a cause for the stutteringNick B.http://www.precisionmanuals.com/images/forum/800driver.jpg--AMD Athlon XP 3200+ @ 2.25 Ghz (405 mhz FSB)Soyo VIA KT600 Dragon PlusnVidia GeForce FX 5200 128 mb2 x 512 PC400100 GB Western DigitalMicrosoft Sidewinder Precision 2

Just to let you guys know I did unplug my sidewinder and had my first stutter free take off and landing with real weather. Here is what I had set up, I had my CH YOKE (USB), My sidewinder (USB), and my logitec headphones and mic (USB) all plugged in, after I unplugged my sidewinder all my stuttering was gone. I will be getting my CH Rudder pedals (USB) on Wednesday and I will let you know if I the stutters come back. How many USZB connections does everyone have plugged in?
