Hi All, with FSX if I install a second graphics card (or maybe use the onboard graphics as well as the main gpu), is the frame rate for all determined by the lowest, or are they seperate?Thanks for any help.BF

Hi, I think it would be the lowest one. I have a 1gig GTX285 and a 2gig GTX285 running in SLI for nvidia surround and I get a total of 1gig vram.So I think it's the slowest card....

it is always the lowest denominator .. second GPU is not the best thing you can do for your Frame rates Cheers Yair

Ok, thanks both.BF

I have a 580gtx and a 285gtx installed and on each a 22" monitor attached. Windows 7 is configured in extended desktop mode and the 580 is defined as main monitor. Means that I'll have more frames if I remove the 285?

any answer to my question above?

My experience with dual video cards in Win XP is that frame rate is totally dependant on what you display on the monitors.A second View drops fps by 50 %, a third view (on a third monitor) reduces fps to about 33%.But popups generally have little to no impact on frame rate- except large popups such as Overhead or COM panels which do impact FPS substantially.Having both Captain and FO CDUs open simultaneously at different pages is very handy & has no effect on FPS If you integrate Views L & R Fwd by shifting the view angle to accurately compensate for bezel separation, you create what your brain sees as a single, very wide image. Since only one of the views can be in updating mode at any instant, 2/3 of the whole view picture is ALWAYS static. Or phrased another way, 2/3 is always perfect!So what seems perhaps to be an unacceptable frame rate, does actually produce a very satisfactory result. When it comes to multiple views on multi monitors, the old Frame Rate wisdom doesn't necessarily apply.AR
