This drives me nuts!!!In the VC mode (occurs most but not all the time), if you drag your cursor over something that has a tooltip associated with it, you get this weird effect, like the screen redraws up to that tooltip, horizontally...It's sooooooo annoying. I know a couple of peeps get this too, not everyone though..I've tried different drivers too....no idea....http://forums.avsim.net/user_files/164756.jpg

Do you get this in Full screen mode? Just curious, why are you using Window mode? FS has always performed better in full screen vs Window mode!

Ryan,I'm afraid this is a NVIDA bug. There are quite a few people (including myself) suffering from that problem. The only things that helped me fight this is:- Turn off tool tips (which I like to have on)- enable/force vsync has helped me quite a bit (nvidia driver settings)- in full screen when I change from bilinear to trilinear (or the other way around) it will cure this temporarily too.

not for me....it never has....FS always works better in windowed mode....because you're not limited to v sync ie (monitor refresh rate, mines 60Hz = 60FPS)sorry, that sounded rude, I just meant to say for me its been opposite, thanks for the hints peter....I like my tips, but if it helps maybe i can turn them off.....

>Do you get this in Full screen mode? Just curious, why are>you using Window mode? FS has always performed better in full>screen vs Window mode! I just got out of the cockpit in FSX after switching back and forth between windowed and full screen mode. I noticed virtually NO difference in FPS, running 1280x1024x32. Granted there are a lot of variables so I doubt seriously that anyone can make a blanket statement such as yours. As to the original posters problem, I've not seen this sort of occurance where tooltips are concerned. The only time I've seen such slow refresh is if I happen to have the cursor on the tool tray or when FSX has gone to "slide show mode" for reasons that I'm still trying to isolate. I have a ATI X1600 Pro video card running the most recent ATI drivers. You might try turning off tooltips and testing to insure that what you are seeing is, indeed, a result of the tooltips display. Also, is this occuring in all aircraft or just 1 or 2 ? Paul

H i Paul, happens with all planes....usually its fine in windowed mode, but as soon as i switch to say like my internet browser window, then go back to FSX, i get the weird thing again. Its not just tooltips, its wherever theres a clickspot, like a gauge that can be clicked or a switched flipped...

I get his too, but not all the time. When it does happen it will affect all aircraft and both 2d and vc. It isn't related to windowed or full screen mode.I guess that now raises the question as to why it doesn't do it all the time. Your bilinear/trilinear comment might be the clue Pete.Greatest Airliners - DC-8Greatest Airliners - 727 Whisperjethttp://www.dreamfleet2000.com/gfx/images/F...BANNER_PAUL.jpg

I also have an NVidia card and suffer the same problem (in both VC and 2D mode). At first, I thought I overclocked my processor or memory too much and fiddled with the OC settings. No luck. The only work around I found is this: after the problem starts, I save and reload the saved flight. Then I avoid opening any other windwow like the plague for as long as I keep flying and the problem does not occur again. Try these tips and let me know if they help

Try adding this to the DISPLAY.NVIDIA section of your FSX.cfg file.RenderToTexture=1Bill M

I can confirm this is an nvidia bug and not an FSX bug because FS9 does the same thing for me. It does it when ANY window overlays the FS window, be it a tooltip, a subwindow, a dialog box, the alt-tab box, instant messenger, whatever. I got around it by disabling tooltips and avoiding overlaying the FS window.I haven't reported it to nvidia because both times I've reported a driver bug to nvidia they just tell me to uninstall the driver and buy another video card or go back to some ancient version of the driver and "wait for the next release". In fact, this started happening to me when nvidia tech support had me uninstall and reinstall their driver three times because the new nvidia control application guesses the wrong language for my computer.

yes it happened in fs9...i forgot!!!

same append to me . set antialiasing on solve evereting

I've got the NVIDA 7900GTX (512 MB) and have never had this sort of problem. Here's my secret:When I'm running FSX I don't run ANY other programs. :)P.S. is that the Carenado Beech Mentor? I LOVE that plane! :(
