Amazing tweak for FS9 on WinXP+Intel HT CPU

Recommended Posts

>have totally smooth>and fluid performance in all areas, with max autogen, sounds great but would like to know if you are running some complex panel/aircraft with those setting. Something like Flight1's Meridian or PMDG's 737 or even some PSS aircraft - a complex panel can really slow things down.Michael J.

Sorry Michael that is a good question. I only have the Beechjet 400A from ES and it performs the same way, though sometimes in switching views there is a slight delay in the texture loading in the aircraft, but it's very very brief. Frames and sim smoothness are same with the Beechjet.I am waiting for the patch for my Meridian and can't wait! I need a good heavy now too. What do you recommend as the best, but some kind of reasonable compromise with performance in a 737, 757, 747, etc . .Noel

I'd like to try the approach with the command syntax and have downloaded the imagecfg.exe file but have no idea where to put it in order to make it work. Has it to go into some windows XP subfolder? Many thanks for the help!Roland

If you put imagecfg.exe into your system32 folder it'll work everywhere.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Washington, D.C.

Noel; It's much faster with HT disabled than enabled with FS9 trying to run across the vCPUs. But it's still a couple fps faster with HT enabled and the processor affinity setting...probably due to ancillary processes being run on the opposite vCPU by XP.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Washington, D.C.

Guys,Tried it last night (I have a P4 3.06 533) and both CPUs are working- but no improvement shown in performance.Could someone tell me how to check my Bios to see if Hyperthreading is enabled there? Sorry for the stupid question.Best,Joel

Command syntax (in a Command window):>>IMAGECFG -a 0x1 fs9.exe>>This writes a processor affinity mask into the executable. >0x1 specifies virtual CPU 0, 0x2 specifies vCPU 1, and 0x3>uses both 0 & 1 (default).

If you have time a walkthrough would help a ton. Thanks!Ranger

Hi Guys,I just wanted to give an fyi about my experience with my system and say that although I've seen these posts around about issues with H/T and FS2004, I didn't expect to see any difference on my system by either, disabling H/T or setting the processor affinity. I had noticed for a a time that whenever I pulled up TaskInfo2003(equivalent of the Task Manager) that only one of the logical processors was loaded by FS2004. But when I saw the post here about a performance increase in FS2004 for H/T enabled machines, I decided to go ahead and try it, even though I expected no change in performance. Sure enough, there was no change after setting a processor affinity. As far as disabling H/T in the BIOS, I didn't see in change in performance for FS2004 there either. But, I did have a problem when I first started using the RealityXP Garmin 530XP, which starts up a Garmin Trainer 500 helper application(it talks to the Garmin 530XP). This program is a 16-bit application. When I would load up a plane with this Garmin 530XP installed my FS2002/FS2004(take your pick, the 530XP has been made for both versions now) would slow to a crawl. At least when viewing complex scenery, such as a city, or mountains. It took my a while to figure out what the fix was, but it was to turn off H/T in the BIOS. I believe this has to do with the fact that the Garmin 500 Series Trainer uses the Windows XP 16-bit subsystem(emulation layer?). As soon as I turned off H/T in the BIOS I was back to normal in MSFS and could use the Garmin 530XP from RealityXP. Yeah! I was the original person to find the fix for this problem and now Jean Luc is telling folks in the RealityXP forum, that have H/T systems, that this is how to fix the problem. Again, this is the only time I have had an issue with H/T on my system.Cheers,Jim RichardsOne Tin Soldier

I tried the affinity tweak on my 3.06 533 last night, no difference in performance at all. Am I understanding correctly that the improvement takes effect only if you turn off Hyperthreading in the Bios?Best,Joel

Hi Joel,The only way the setting an affinity would even have any effect is if you have H/T enabled in the BIOS. Right now I have H/T disabled so I can run a plane with the RealityXP Garmin 530 if I want. When I open up the Task Manager right now I don't even have the option to set an affinity.Cheers,Jim

I have the Intel D875PBZ motheboard, and P4 3.2 GHZ processor all with HT. I tried this, and it seemed to have NO change. I'm glad it works for some.- JD

It's not a command line used to start FS...this will permanently write the processor affinity mask into the FS9 exe file...do it once, and it works every time FS starts.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Washington, D.C.

Same here, no effect at all, even worse performance to be honest.But I am quite happy with my Radeon 9700, P4 2.6@3.25GHz, Abit IC-7.Lorenzo
