I recently had the (dis)pleasure of having to do a full system rebuild - thanks to Mr lightning bolt directly striking my house. No matter what I did, I could not seem to restore my FS2004 performance to what it was before the rebuild, and I was getting a stuttery 7 fps at KLAX with only 50% AI, a few puffy clouds and most sliders in the middle. Even disabling default.xml couldn't revive my fps.A few key tweaks later, thanks to some good tweaks posted in this forum and one I found elsewhere, and my system is now much perkier. In fact, even perkier than my previous installation. Cutting a long story short, there were three key things I did to open the can of FS2004 performance whoopazz:1. The tweak mentioned yesterday in this forum to turn down hardware acceleration on the secondary adaptor - stuttery texture loading is now a thing of the past!2. Intel Application Accelerator V 2.3 - but not by itself. In fact by itself, my orginally poor fps dropped even further.3. Intel Chipset Software Installation Utility V5.02.1003 - when I loaded this puppy up, the the Intel Application Acceleration straight afterwards, my fps went through the roof. Ironically, FS2004 now takes ages to load compared to before (over a minute), but once it is going I see my fps mostly pegged at 30 (my capped setting) and only rarely dipping below this.As an example, I recently finished up a flight at EGLL with 80% AI traffic (Ultimate Traffic + updated AFCAD2s to boot), almost all sliders to the right (autogen one notch off full right, cloud draw distance 80nm), 6X AA and 4X AF, PMDG 737NG (2D panel) and clouds aplenty with AS2004, even reenabled default.xml and I was getting over 20 fps looking out the cockpit and high teens panning around in spot view.Sorry that this may not be much help to the AMD crowd, but I thought I'd post my good fortune for the potential benefit to those in the Intel crowd who haven't yet tried the Intel Chipset Software Installation Utility and Intel Application Accelerator cocktail. Worked great for me!Gary

Hello,Where did you find "3. Intel Chipset Software Installation Utility V5.02.1003 "?I can only find the V5.02.1002 on the intel site.

Yes. Could you please tell us where to get all this great stuff. We could use the help I'm sure. Specific links would be most helpful.

Hi,Well what I found on the Intel website was v5.1.1.1002 (12-12-2003), so I went ahead and updated mine with that version.Jim

So do we need the Intel Application Accelerator AND the other Intel thingy? Man, I sound smart!!!!:+

I was just about to ask that. Although, I've been reading the intel site about that util, and it sounds great:http://www.intel.com/support/chipsets/iaa/index.htmHere's a link for that other thingy:http://www.intel.com/support/chipsets/inf/index.htmDon't forget the restore point!sg

You dont' run IAA. You install it and it runs automatically. This hsould have been installed right when you got your Intel cpu. Running an intel system without this is unheard of. This is one of my very "first" installs after a clean format.

Well how about that! I had never even heard of it until this morning - Would you mind telling us what your "second" and "third" installs would be? ;) :) ;)sg

Any means of detecting whether or not it is installed in your PC? I have an 845PE chipset.Steve

You would have a program files/intel/intel application accelerator folder, an uninstall entry, and a start menu folder...EDIT - also, in the readme of the download, section 5 has an extensive description on verifying if it's installed.

Hello,My opinion : you can install it more than ones, I had it installed on my PC and I did install it again without any problem.I suggest you make a "intel" folder with sub-folder "IAA" where you save a copy of the .exe.I also have a 845PEHope it helps

hmmmmm... ran it for a while last year, all apps were very sluggish starting up, opening new windows. took it off after a week or two. have 850.not to discourage anyone. just noting that the benefits may be extremely dependent on your specific hardware.vilk

Note: IAA is incompatable with some Intel chipsets.See: http://www.intel.com/support/chipsets/iaa/index.htmDavid

"Well what I found on the Intel website was v5.1.1.1002 (12-12-2003), so I went ahead and updated mine with that version."There is seems to be 2 sifferent files to download. Which one is itRon
