In WinXP, vSync force works in the ATI CCC Control Pannel for FSX and FS9. However in Vista/Win7 it does not. At least not without a 3rd part app simular to Nhancer. There is ATI tray tools for forcing vSync in Vista and Win7. I am testing the 10.3 drivers tonight I think though. Hopefully the CCC can force it now. But I doubt it.
So ultimately, when you open ATC on nVidia cards with vSync forced, you don't get the screen flash or blink? With ATI on Vista this only happens with vsync forced. This flash doe snot happen in XP thankfully.
I have to find an nVidia system to test this on (ATC window open and close) or grab an eval one of my own. If you can force vSync on Win7 64 without any screen flash in ATC window I will switch as I said. I really want 64bit for it's benefits to FSX.
Thanks for the info.
let me chime in my ati problem (well not really, had it on nvidia as well)
ive changed gfx card to 5850 from an 8800 gtx which died.
the sim runs smoother now (almost no micros stutters , that plagued me before in tongass) ,
but some of the addons make my fps drop , some more some less . the addons are :
Captain Sim 130
Iris PC 9
the Iris PC 9 is the worst ( going from a smooth 27 to 17 ) , the thing is that ive had the same problem with the 8800 gtx , driver try and error helped with that , but i could never get the driver which gave good fps totally stutter free . With ati, i dont have that many driver choices .
im running all this on a i7 oc to 4.2 , 6gb cl7 ram. xp64
did any one experience anything similar ? i read somewhere that it could be the reflections in the cockpit and the alpha channel , but i dont know how to fix that . the only other thing i could think of is to reinstall windows , which i didnt do when i swapped cards, just uninstall drivers and safe mode driver sweeper.
any help will be appreciated . tnx !!
Those addons are a bit hard on most systems..but Yea, it might have something to do with what you said.
maybe check with theor support sight and see what others are doing to fix that problem..
I see no need to reinstall windows... Its not a window problem I think...
You have plenty of CPU thats for sure. i would suspect the add ons...
as i said, must be a driver problem, had the same issue with nvidias, only one driver worked .
found one more addons where this is exhibited : the 1.5 version of the duke
I've got the CS 130 and mine runs fine, I7 920 2.66Mhz. I've used two drivers for the 5850 and not really noticed any differences between them. Can't comment on the others as I don't have them. Computers are just like women !!!!
which drivers did you use and which os ?
I moved to an ATI 4890 other than the fan noise which Goes away after it warms up this card does a really good job with FSX, My FSX Happy was a Simple increase in the TEXTURE_BANDWIDTH_MULT=140 - 180.
Dunno why, but FSX was Smoother after the change -
