Hello,

 

I use FSX on a windows 8 Toshiba laptop and I have to say I didn't even expect the game to open but it runs actually really well and I can cram up tthe graphics settings and it still runs well. The only problem I have is with changing the simulation speed on long flights. Because I don't want to sit in front of the computer for ten hours, I normally change the simulation speed to 16x after reaching cruising altidude and the autopilot has been engaged. The problem does not occur when I change it to 16x but when I change it back to normal speed. About 60 seconds after I changed it back to normal speed, no matter what I do or what situation I'm in in the game, the game freezes and I get that dreaded 'FSX is not responding' message. I've tried everyhing. I've tried saving before and after I change it to normal speed then exiting the game and repoening it, I've changed the graphic settings, I've even played around with the game's compatibility settings but it still crashes approx 1 minute after I change it back. 

 

Has this ever happened to anyone out there? Is there a solution or suggestion you know of that may fix the problem?

 

Thank you so much I appreciate any help you may have!

Some have fixed this problem by pausing FSX just before lowering the speed to normal.  You can try pausing after you have lowered the sim rate too.  You are using a lot of system resources when you increase the sim rate and this allows the sim to "catch up".  I heard a long time ago that there were issues with the 16x's rate but cannot find it now.  As I recall the Microsoft developers were recommending a speed no higher than 8x's.  If you have a lot of other things running in the background, like real weather, atc, an AI program, using a commercial aircraft from Aerosoft or PMDG, flying over commercial scenery and not the default, then this only increases the chances for something like this to happen.  High FSX settings and a bad tweak like BufferPools will do it too.  You should look at your Event Viewer to see if there are any events showing these freezes and if there was a module that caused it.  AppCrashView can probably pick it up too especially if you received a message that FSX has to close and they are looking for a fix.  You can get more details of these two programs in the AVSIM CTD Guide (see pinned topic in this forum).
