Hi all,For those who still have stutters in FS2004 in a dual (or more) monitor setup I believe I found out a solution.On my system when I disable hardware acceleration on the second video card the stutters stop!You can disable acceleration via the control panel, screen. (Problem solution.)Hope this helps!Norbert

Interesting Norbert-and it works!I run three monitors, and always had horrible stutters with fs9 in windows mode. I always ran fs2002 in windows mode because of the dramatic frame rate increase.Your suggestion eliminated 99% of the stutters in windows mode. (Nay-really 100%.)However-one caveat: If the second or third video cards are set to anything less than full acceleration, and you go to full screen mode (ALT>ENTER) fs9 will not allow transfer of any panel to the 2nd or 3rd monitor. Makes sense, as full screen mode enables hardware acceleration, and is there is none enabled, it is useless to the program.Soooo---the choice is interesting. After a few trial flights, the frame rates seemed a bit higher in windows mode-with no stutters, vs. full screen with full acceleration on all video cards. (Maybe 2-3, not as dramatic as in fs2002)Will keep experimenting both ways, as a lot of variables are always present in fs9--weather, clouds, scenery density, etc.But-your post is appreciated! Another work-around to be considered!Thanks-BaronP.S. Haven't you posted before on multi-monitor problems and solutions?

Will this work with one video card that has two VGA plugs on it? For example, the Geforce 4 MX440 card is a dual monitor all-in-one video card.Does the hardware acceleration need to be disabled from the DirectX diagnostic tool in this case?Scott

>You can disable acceleration via the control panel, screen.>(Problem solution.)Norbert,Exactly what screen are you referring to? What operating system are you using? I could not find a "disable h/w acceleration" option anywhere. I'm running XP Pro. The only option to disable h/w acceleration that I found was in dxdiag - but that option disables it for all video cards. Doing so dropped my framerates from ~18 to ~7.Thanks.-michael

I found it (Display -> Settings -> Advanced -> Troubleshoot).Thanks.-michael

>Will this work with one video card that has two VGA plugs on>it? For example, the Geforce 4 MX440 card is a dual monitor>all-in-one video card.Yes, it will. I just experiemented with a dual-head FX5200. I use NView to configure the two monitors on the FX5200 card in "dualview" mode. Then, for each monitor, I set h/w acceleration to the third tic-mark from the left. >Does the hardware acceleration need to be disabled from the>DirectX diagnostic tool in this case?No. Disable it as follows: Go into Control Panel -> Display -> Settings. Then select the monitor you want to set the h/w acceleration for. Then Advanced -> Troubleshoot. This will bring up the h/w acceleration options.-michael

Thanks Michael, I'll give it a try.Scott

Norbert, are you still following this thread?Judging by your user name, I am wondering if you are using dual monitors on the A320 Pilot in Command package?I like A320PIC, get framerates about 13 on a 3 Gig AMD cpu (getting about 40 fps on the default MS planes). And was wondering about buying a second monitor to try out putting some of the PIC popup screens over on 2nd monitor and enlarging them there. But if 2nd monitor decreases framerates a lot, well with PIC there aren't many framerates to begin with, even on one monitor :/http://pweb.jps.net/~westerners/sitebuilde...res/a320pic.jpg

I used to fly A320 PIC but couldn't cope with the frame rate problem. I tried a two monitor setup but was not satisfied with the result. The popup screens however have a far better performance if undocked but the overall performance dropped too much.I am now flying PMDG737-700 in a two monitor setup. And with the new solution NO stutters and excellent framerates in FS2004.Could you not try (borrow) a second monitor and see what your system will do?Norbert

FS9 was not designed to work in full screen mode. That is why undocked screens always go back to the primary screen when you switch from full screen back to windowed mode.So your undocked panels on second and third monitors do not need any hardware acelleration.Result: stutter free FS9 in a multi monitor windowed setup.I did post some "stutter" messages before but that was to ask if anyone was coping with the same problem. I did not have the solution at that time.Norbert

Michael,Did it work for you as well?Norbert

>Michael,>>Did it work for you as well?>>NorbertYes it did! I played around with several settings and found that I did not have to completely disable all h/w acceleration to get the stutters to go away. I have h/w acceleration set to the third tic-mark for my PCI card (dual-head GF4 FX5200). Since I'm using NView's "dualview" mode, I actually had to set the acceleration for each of monitor 2 and 3 to get it to work.I am very pleased with this because I had been experimenting with 767PIC in FS2004 using 1 monitor on my AGP card to display the outside view and 2 monitors on a PCI card for the main instrument panel. While this setup worked fluidly in FS2k2, in FS2004 I was getting the annoying stutters every 11 sec - like clockwork! With that said, I think we should nominate you for the AVSIM "Technical Solution of the Year" award. ;-)-michael
