I'm 'bout ready to just dump WIN7(64), save this one last effort to save it. :-) I've had WIn7 64 for about 6 months now and everything seems ok but for this nagging issue; poor hard drive performance. I can play a looped 30 sec 20mb video clip and the OS will only read the file directly from my hard drive never from ram. While capuring and playing back video it's like I'm not gettting any DMA or write-read cache, although drive benchmark software tell me everything is fine with my drives and hardware. One other observation while using FRAPS in Win7 that I don't see using in Xp32: I get some kind of video sync when I capture. For example, if my framrate within FSX is 80 to 100 fps FSX will sync down to 30 FPS when I start FRAPS capture. If FSX is running under 30 FPS the "captured" frame rate will sync down to exactly 50% of the noncapture frame rate. -I do not have and kind of video driver Vsync enabled ....as per Nvidia Inspector. When compared to WInXP, Win7 video performnce is horrible in FSX is horrible. With Win XP I can run FRAPS and actually forget it's on. On the otherhand, WIn 7 FRAPS performance (with pretty much the same FSX settings) brings the system to it's knees. Any help/tips would be appreciated by me,Ken C.

Why not use Windows 7 system benchmarking on yor HDDs (or one of the free PC benchmarking utilities) and see what you get. A 7,200 rpm HDD should give you 60-70 MBy/Sec and a 10,000 rpm HDD about 90-100 MBy/Sec sustained when copying very large files. Also make sure you have the latest motherboard drivers installed from Asus and Intel. I suppose you also have the latest version of Fraps.Cheers,- jahman.

You don't really say what the symptoms are? Is it stutering? I don't use Fraps.1) Update video drivers2) Update chip set drivers3) Disable Aero Themes4) Try moving to your SATA controller.5) Ensure you are in "high Performance" mode in your Power plan including checking advance options are set to never power down.6) Page file set to system managed.7) Ensure NCQ is not enabled.8) Ensure write cache is enabled.

Thanx guysI solved the problem that has caused me months of grief with win7.The problem? Windows7 Media Player. Uninstalled it and installed a 3rd party media player and viola! Fraps capture is as smooth as a babies &@($* and my video playback is now cached. I now now have real life direct memory access with video capture and playback.Ken
