PMDG is a small software company, currently employing 9 members from all over the world who all share a passion for flight simulation. In nearly 8 years of business, PMDG has come a long way from initially producing detailed manuals to developing complete airliner simulations today.

In order to bring the sophistication, technical details and challenge of commercial airline flying to the enthusiast, we ensure that our products meet exacting standards for quality and completeness. This is verified by our dedicated Beta Test Team, compromised of aviation professionals, airline pilots and Flight Simulator experts. Currently, it is comprised of the following individuals: Marc Brodbeck, Dennis DiFranco, Mats Johansson, Lee Hetherington, Sam Kalachoras, George Morris, Randy Smith, Andrev Thomsen, Travis Waycott, Jane Rachel Whittaker and Terry Yingling.

In addition, PMDG is proud to work together with a dedicated team of aviation professionals not only for beta testing but also technical advising. This enables us to produce products of unmatched detail and quality. Our current Technical Advisory Team includes: Captain Nikos Aposporis, Captain Joe Batt, Captain Jon Bunting, Captain Tom Falley, Captain Steve Weiher, Captain Alexei Nicolov, Captain Stefan Schweizer and IR Ozzy.

The MD-11 Technical Advisory Team has the following members: Markus Burkhard, Bernhard List, Urs Zwyssig, Remco Kappert, Anthony Borreson, Andre Fedrizzi, Paul Garcia, Reinaldo Menegoli and Matthijs Ledegang.

I actually have the PMDG MD-11 for FSX if anyone would like to know anything about it...first hand.

I love it. It costs too much, but it is the closest thing to real for a heavy jet I have found for FS.

Here is some information I just read in PMDG OPS:

Hardware and Operating System
First, let’s address the issue of Operating Systems. At PMDG we have tested FSX on a broad range of machines, and we have some strong, clear recommendations to make regarding your selection of operating system when using FSX.

PMDG strongly discourages using FSX in the Windows Vista operating system, regardless of how much processor speed, video capability or memory you may have.

If you intend to use FSX and stick with only the default aircraft, and do not intend to add high density scenery or weather programs, then FSX should operate effectively on any machine that uses Windows Vista and has at least 2GB of memory.

Vista and OOM Problems
If you intend to use complex add-ons such as the PMDG 747-400X, and/or add complex scenery and/or weather packages, Windows Vista in it’s current form will cause you nothing but frustration and heartache through unreliable performance, Out of Memory Errors (Operating System Generated) and random unexplained CTDs (that are almost certainly uncaptured OOM errors.)

Why does this happen? Windows Vista has drastically changed the way the operating system handles hardware memory management. The full explanation is very technical and involves an aspect of the OS called “user address space,” but the end result is that the combination of the 747, FSX and Windows Vista appears to be highly susceptible to OOM and CTD errors triggered when the operating system fails to manage memory correctly.

This type of error is not unique to FSX as they occur in many other games with high memory usage. This has been documented by several websites like AnandTech and HardOCP. The combination of the way Vista manages memory, FSX’s already high RAM overhead, and our intensive cockpit systems simulation simply overload the amount of user address space available and the sim crashes.

There is some thought that the 64bit edition of Vista might be a potential solution to the issue due to its increased memory handling abilities versus the 32bit edition. We have not been able to test this however, but you are welcome to do so. If you are successful in using either edition of Vista without these errors, we would like to hear from you in regard to your system configuration and anything you may have done to make that possible.

We have been hoping that this problem would be resolved in Windows Vista SP1, but based on currently available information, it does not appear that this problem will be fixed.

You can read more about the Windows Vista memory handling problems here:

For best performance, PMDG recommends installing FSX under the WinXP Operating system.

By the sound of it it seems that Vista is just a load of c--- to the flight sim world.

You can't beat XP as an operating system for flightsimming.

I would like to here from all those who have Vista and what they think about it
Dave

I have been using Vista for a while now and it has performed flawessly. But, I started out with a new PC. I think the trouble begins when you try to install Vista on an old outdated PC.

Thanks Robert, have you FS9 installed as well.
