Hi all i have a question, I run the PMDG 737 on shuttle flights in the uk i have UK2000 egbb, egss and egph, AES, active sky and radar contact installed all my sliders are maxed and i use a two monitor setup ( PMDG panel on lower and outside views on a upper) All runs great and and my frames are locked at 25fps, with this the lowest it drops is around 20fps when i fly around the london area. Now i recently started doing some shuttle flights in the USA and mainly fly from KBOS to KSTL, i use the freeware KBOS with AES and get again around 20fps i use a freeware KSTL and i am lucky to get 11fps around the airport area which is awfull, I've noticed it alot around the USA that the land mass really drops the fps why is this and why in the USA but not around the UK, is there any way to help bring the frame rate up by updating the Mess. I havn't added any payware US airports as yet but i want to get the Fly Tampa KMDA but if i get low fps with freeware what chance have i got with a payware package?chears all hope this makes sence

Are you running add-on traffic? First thing that comes to mind is that the Northeast US has A LOT of traffic. Also, what are your system specs? Weather? Other add-ons?

i'm using woai and have it set to 60% USA and UK and using active sky advance as the weather program without graphic x Base processor Core 2 Duo E4500 © DC 2.2 GHz800 MHz front side busSocket 775ChipsetIntel G33 ExpressMotherboardManufacturer: AsusMotherboard Name: IPIBL-LBHP/Compaq motherboard name: Benicia-GL8EMemoryComponent Attributes Memory Installed 3 GB Maximum allowed 8 GB (4 x 2 GB) (64-bit OS) 4 GB* (4 x 1 GB) (32-bit OS) Hard drive500 GB SATA 3G (3.0 Gb/sec)7200 rpmVideo GraphicsGeForce 8500GT512 MB GDDR2 memoryI/O Ports: HDMI, dual-link DVI , S-videoSound/AudioIntegrated High Definition audio Realtek ALC 888S chipsetSupports up to 8 audio channelsOperating System Windows Vista Home Premium with Windows Media Center (32-bit)

RobKid: I've been flying Europe (Western and Eastern) and the Mediterranean exclusively all winter (all payware or freeware addon airports) and recently returned to my home airport for a flight between KBOS and KORD (George Grimshaw's and ImagineSim respectively). I noticed the exact same behavior as you! My system specs are below and I run WOAI at 80% -- it's not your imagination, you're not crazy, and it's not just your system. Time to start playing with "sliders" again . . . :(
