April 4, 200818 yr I was reading quite a few articles regarding my HyperThreading capability of my Prescott D0 3.4 GHz P4.Being that I can turn on and off this dual-core emulation routine via the BIOS, and that I have had this feature enabled since having purchased this system about 4 years ago---I decided to try FSX with no HyperThreading enabled.It was quite interesting. In an apples-to-apples scenario, without HyperThreading on, I could only get about 32 FPS at max. I then rebooted, and enabled HyperThreading once more via my BIOS.Same KMYR scenario (saved) and same canned weather.I now got into the 40's and 50's in FPS and about the same smoothness on my system.Conclusion: If you have a single core P4 with HyperThreading capability. TURN IT ON! Some references that it slowed down certain applications, has never been seen by myself, and I run the whole gambit. You get at least a 30 percent boost in performance when the CPU is addressing two simultaneous threads. On my machine, anyway.
April 4, 200818 yr You should be USING hyperthread AND you should have this patch installed for hyperthread and multicore procesors in XP:http://www.microsoft.com/downloads/details...&displaylang=enthe internet is full of myths...

I always have run with HT on, but thought to play around and see if there was an actual difference in using FSX. Boy...was there! HT rules for the P4!
April 4, 200818 yr If you had the patch it would have told you it was already installed, so now you are correctly configured for hyperthread use

April 4, 200818 yr Well, I know it would stop with a "already installed" message in x64 but its been so long since i used a 32bit version of Windows I can't remember if it did the same thing in x32 or not.I know for a fact that patch was never available at Windows Update and you had to know about it to get it.. so I am sure you did not have it installed.
April 5, 200818 yr Author Well..if it could not come from Windows Update and that you had to know about it...you are probably most right that I did not have it installed. I do now, Nick.Thanks for the tip and lead!
