There has been massive discussion on tweaking FSX for those who are experiencing low performance. One thing that has been posted is "turning Autogen Off" as a way of reducing the overhead.Don't do this, reducing Autogen much below normal has a negative effect, which is quite the opposite to reducing the autogen slider in FS9. Post containg incorrect advice to some users are from users who are not that experienced themselves.My advice is to check Ryans (Tabs) tweaking guide, also NickN over at Simforums. There are some really knowlledgeable people on this forum, deciding who is right and who is wrong is the hard part. Also one of the first things anybody should do before tweaking there fsx to death, is to make sure your Bios is set correctly, this is often overlooked, and most new motherboards are set up with default settings like power saving and memory timmings etc. So it is essential that your bios is set before installing OS and FSX. Such a complex aircraft like the NGX requires a well tuned balanced system, tweaked, but not over tweaked. For those experiencing low performance, I hope what I have posted helps towards your goal of flying the NGX in a stable system. Good Luck

I never knew that. I don't tend to use autogen anyway because I use a lot of photo scenery.

Autogen off = Win for budget pc's. For my system I have 0 autogen because comeplex planes like the NGX combined with REX,UTX &GEX seem to use up resources. Using default planes is a different story.

What I posted Kevin was to illustrate that turning off autogen is not going to achieve the results you think. Of course if you are fliying using photoscenery, turning off AG won't make any differnce.

Try upping your Autogen 1 notch from zero and you wil actually see an improvement of your framerate! Also see a link on the Aerosoft forum:http://forum.aerosoft.com/index.php/topic/30940-warning-autogen-null-off-can-generate-problems/

ki ora Tamati, I wonder if you reap the benefit of UTX and GEX with AG off ? How does it affect what you see ?

Is that always the case? If so I'm going to try that....

In most cases those lines will throw off the priority system and make the sim run/stutter worse.2. Believe it or not, ZERO autogen slider can make frames drop, how? Same reason as above. Try to maintain at least 50+% (DENSE) however very slow systems may need to limit that to NORMAL/SPARCE or even OFF (off = rare must be very slow hardware)Keeping the autogen slider at DENSE or greater actually tends to raise frames. Going too high for the installed hardware and Scenery Complexity/weather is where perf starts to really dropMany can run a 3/4 (very Dense) Scenery Complexity with a 3/4 (very dense) autogen silder however your mileage may vary.The important part about this slider is if your hardware is not very slow, keep it at a minimum of DENSEThis slider can also be changed mid-flight as well. There are times when you may fly out of a scenery friendly hub, into a very large urban area hub which may require this slider to be dropped a notch Good systems can run 3/4 to 100% depending on the scenery involved and GEX USCAN can go a long way in helping with that performance. Autogen was laid out in a optimal way to reduce CPU overhead."

Thanks for quoting Nick Lenny, I was being lazy
