FSX-MS Undocking a panel causes FPS to drop by half?

[Bob Scott 7,719]

I just tried this for grins. I set it to DX10 mode and the problem went away. It's not a solution though because as soon as I move the undocked panel to another monitor the panel becomes just a blue/white FS logo, plus with all my add-ons DX10 Preview messes so much up. Interesting nonetheless.

Are you, by any chance, running with vertical sync forced on in the driver (or in a drive utility like nvidiainspector/ATITools)? That could cause your problem--in windowed mode there is no double-buffering of the video frame buffer, which can cause big hits to the frame rate.CheersBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

cant seem to find any options for vert sync in the game, driver or catalyst

In catalyst it's called "Wait for Vertical Refresh"In FSX, there are a couple of params in the display section of fsx.cfg, one for full-screen, one for windowed mode (ForceFullScreenVSync=1 or ForceWindowedVSync=1)CheersBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

Noah,Did you ever find a solution to this problem? I am having the same issue (in FS9 though).ThanksJon

... guys, I had the same issues. got tired from going around and around, those issues (and many others) are (unfortunately) much more complicated then we think they are.so,here is the tip.Get in touch with Michael from www.fs-gs.come-mail ramsa329@msn.comand listen to himCheersYair

So after reading a few things posted above, I tried running FSX without the FPS limiter and bingo, the undocked windows frame rate drop disappeared. One window undocked (GPS) and moved to monitor #2 had no frame rate loss, two (TCAS radar) caused a slight loss in performance and three windows undocked caused another slight loss. FSX was still smooth however, so it was quite usable. I'd like to thank everyone for sharing their ideas; certainly helped me to solve this minor issue!

My problem was the framelimiter i got rid of it and theres no difference when i undock and drag a panel over to my 2nd monitor glad i found this topic thru google i thought it was my GTX590 thx for the help gentlemen

Like Andy said...With FPS Limiter set it to the double FPS ie. if You ran 30 FPS then set it to 60.Only problem is, that if I have no undocked windows on the 2. monitor then FPS on the main monitor is allowed to go up to 60.With panels undocked on 2. monitor FPS will be max at 30 as set.The good thing is that eventual big FPS spikes are caught and kept down by the FPS limiter - givinhg a smoother performance.Finn

Old topic but I'm wondering how people get on with this?

 

If I open up 2 viewports inside the main view, frame rate tanks, is this normal?

 

To avoid distortion, I see people running 3 monitors with 3 viewports. Center with VC view, then 2 other views showing 2 additional viewports (left and right VC window views). How are they able to maintain enough frame rate?
