Hi Guys,
I just wanted to 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 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 on avsim 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 talk 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,
