For anyone using lower end systems like me Windows XP 3.0 G Quad Core 4GB Ram 1GB graphics card Moderate graphics settings/no Ai traffic/No water I have found that by not opening any 2D panels during flight, especially the FMC I have had no problems. I have completed a few of the tutorial flights EGKK-EHAM with no problem ( landed using HUD). I currently have no addons at all installed except the NGX. I am using the NGX in VC mode only. Hope this helps some of you. Got to say …….What a great job PMDG have done here, it is truly amazing. I am sure given time these issues will be sorted, Cant wait to get home tonight and go again.

Good to hear. Must be very specific to your OS or machine. I am flying with the FMS in 2D undocked on a second screen. I have had two early freezes that have gone since HF3. Mark.

Blimey! You have got some good spec there Mark. You could probably fly the Space Shuttle with that Flew a flight last night and had some freezes. Then realised that I had automatic updates turned on plus my antivirus tried to do an update. Turned these off and flew the same flight again (Eham - EGKK) ....... no problems. Thinking about adding some terrain.. am I mad!
