I flew north out of Seattle with the sliders for mesh and texture nearly maxed until the program crashed, and I made notes of readings as follows:Total available system memory = 3.582GB (out of 4GB installed)Total Memory usage at crash = 72% of above (27% without FSX)FSX memory usage at crash = 1.556GBRemaining available memory at crash = 0.995GBThere were the customary scenery spikes into the sky and floating autogen prior to crashing and then the message displayed that my computer was out of memory. Why doesn't more of the installed memory get used, or is this actally a video card memory issue?This type of crash often happens with long flights and with less memory usage. I just turned the sliders up on the test to expedite it. Are there any hardware settings that can help this, or is the only option to reduce FSX sliders?Thanks.ArtNow flying with: Biostar TF560-A2+, Athlon 64X2-6000+, 4GB RAM, Geforce 8800GTS-320MB, 500W PSU, 250GB HD, FSX (SP1-SP2), Vista Home Premium 32 bit

Hi,I had the same problem with FS9/FS2004, this is a post I uploaded a few days ago. It seems autogen was my problem, who knows maybe the problem still exists.Previous PostI thought Microsoft fixed the problem with Autogen. I tried running a 9 1/2 hour flight (Real Time) from SBGL (Tropicalsim) to KATL (Simth's Designs) using Level-D's 767, with Autogen on I get a CTD on final approach into KATL. This happens every flight.1. I spent a week testing in real time, with Autogen the flight ends during the approach with a crash to desktop or FS Freezes, this happened every flight.2. With Autogen renamed to .BAK the flight continues into KATL without a problem.The system has plenty of hard drive space (100 Gig) as well as ram (4 Gig). Windows XP Pro's memory is managed by the system. I do not have anything running in the background and I turned off most of Microsoft's services ( Followed FSGS's System Unification ).I don't see how its the system.System Specs1.

It is certainly hard to believe that an upper echelon computer system cannot complete a long flight with autogen enabled, but I guess that is the case. My recourse is to stop the flight when graphics begin to show anomolies (at least it is giving me warning signs), save the flight, exit and restart FSX and reload the flight. :(Art

I'm not sure what to do either, FSX was getting pretty stuttery today....the RAM usage for the PC was nearing max of 2GB, FSX was using 1.3GB alone of my 2.....so it's pretty crazyUTX and UTX Europe don't help hehe
