HiI need to run in windowed mode because i cannot run squawkbox as a module.Therefore i need to alt-tab quickly between SB and FSX to read/write etc.However, i'm getting severe performance loss in FSX windowed mode (maximized).Both my in-game and my desktop resolution is 1440x900.Yet, full-screen FPS is 18 and my windowed FPS is 12. My GPU does not downclock when FSX is windowed.Another solution would be to use 2 monitors (which i have). But my fps also drop when using 2 monitors (gpu thing?).Any help?Thanks

you say Windowed maximized - meaning it completely fills your screen, correct?try reducing the window size a few pixels so that it is not completely maximized and a little of the dektop is showing.See if that helps.Vic

Auto Hide the task bar, if you haven't already, and see that helps.

Thanks that did it :).. just when i installed FSINN.Might just get used to that because i can use it in-game

Could be a little more math involved to convert from less to more pixels. Just guessing.jja

If you have VSync turned on, then it's "quantizing" of the frame rates to be evenly divisible by the monitor refresh rate...your frame rate will snap to the next lower value of FSX frame rate divided by an integer. If your monitor refresh rate is 60 (common for most LCD monitors) then an FSX frame rate of 60+ will snap to a frame rate of 60 (60 divided by 1), 30-59 will "snap" to 30 (60 divided by 2), 21-29 will snap to 20 (60 divided by 3), etc.Also, if you leave a little strip on the side or bottom of the desktop in windowed mode, and move your mouse cursor outside the FS window, you'll see a ~4-5 fps increase. That's an FSX bug that we'll never see fixed.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

There is no mention of what operating system is being used. If it's Windows Vista or Windows 7, use a Basic rather than an Aero desktop theme.

Need to correct a misstatement I made in the above...with vSync operating in windowed mode the frame rate snaps to the next lower value of the monitor refresh rate (not FSX frame rate) divided by an integer.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

I'm using Windows 7. When I start FSX it automaticaly turns Aero off before running FSX and then turns it back on when FSX closes. Is there a way to keep it from turning Aero off ? For me its only the task bar that slows down FSX in window mode. I'd like to try it with Aero "on" if its possible. If Aero doesn't slow me down much I'd like to leave it "on".

I assume then that you followed the following instructions from Microsoft for running FSX in windowed mode:To disable Windows Vista Glass and Aero features only when running Flight Simulator X1. Open Windows Explorer and navigate to the folder in which you installed Flight Simulator X.2. Right-click FSX.exe and then click Properties.3. On the Compatibility tab, select the Disable desktop composition check box.4. Click OK.I further assume that Aero mode would be left on by not checking Disable desktop composition.But what do I know?

I never knew there were any instructions from Microsoft for running FSX in windowed mode. Thanks for the instructions. :( Enabling or disabling desktop compostion is having no effect on my end though. FSX still turns Aero off before it runs and turns it back on when it closes. Thanks for trying to help me...it was worth a shot. :(

In windows 7 aero is auto disabled once i start FSX..

So I have noticed since posting in this thread. I use full screen mode for flying and only use windowed mode when using FSX with other programs when doing scenery work. Other knowledgeable people (although not knowledgeable in Windows 7) have advised me to disable Aero, which I have ignored since I fly in full screen mode. As indicated in the post, Microsoft's instructions are for Windows Vista.

------------------Just a suspicion here. I run triple monitors/ triple views in FS9. If the slightest part of any view overlaps an adjacent monitor there is a major frame rate hit. I'm guessing that your 1440x900 resolution may be doing just that- leaking over the edge of the screen.Can you drag back the edge a bit to ensure this isn't happening? That is, using Minimised- drag the image edge to exactly fill the available monitor "real estate".Phrased another way, your 1440x900 resolution may not correspond to the physical proportions of the monitor.Alex Reid

I cannot try this right now since im somewhere else, but 1440x900 is the native resolution of the screen and it should match the physical proportions of the monitor.Also it doesnt look like it overlaps
