Hi guys today i installed both of my Geforce 8800 gts in SLI mode in my pc, but now i don't know how to enable it nvidia control panel wise. Please i would appreciate any help.

NVM guys fixed the problem, turns out i didn't enabled sli in bios of my system.

But now i have another problem, when ever i reach about 5000 feet and start to rotate the camera around my aircraft , my fps drops to like 4 and everything becomes extremely laggy and unflyable. Any ideas why? i suspect because of the sli mode, because never happened with only one 8800 gts installed.

What makes me laugh is that with nzone, my system is more than enough to play fsx, but after this hardware modification it is simply unplayable  :'(

I hope you did not buy 2 cards for SLI in FSX

If you did, you wasted your money

In order to have any advantage with SLI in FSX you must be able to run the following:

16-32AA
over 2000x screen resolution (or higher)

and in order to be able to run 16-32AA at that resolution, you better have a very fast quad core running, and, at todays CPU speeds, it best be overclocked to 3.6gig

otherwise SLI is a waste in FSX and will run like crap

I have been posting that about SLi and FSX for well over a year

And to top that all off,  right now Nvidias drivers are not that great either

thanks nick guess i will just return the second card. But i already purchased a quad core just waiting for it to arrive.

Its not just the quad, its the cards too and the monitor

SLI advantages in FSX are in being able to run much higher graphics quality, not increased frames

You must have a monitor able to run above 2000xX and the cards must also be pretty beefy with a large onboard memory reserve for the frame buffer at that resolution

The 8800GTS is OK for that bit you do need the very fast processor, memory and the monitor to run the resolution too

can i ask your opinion, is q6600 quad core 2.4ghz pretty decent for maxed setting in FSX. The way my system will look is i will have this processor, 8800gts 640 card and 4 gb of ram, will this be enough to push the sliders all the way to the right and have atleast 20 fps stable without no hickups?

You want the long or the short answer?

The short answer is no, read the thread at the top of the hardware forum called "Will this or my system run FSX?"


You will get good results but your not going to be pushing the water slider above 2xlow and the traffic very high either

I am overclocked to 4gig on a next gen processor, DDR3 memory at 2400 (1200MHz real speed) and a next gen video card and I am just now starting to see 'somewhat" higher end results but the hardware to do what you are asking wont be around till the end of the year or beginning of next

I am still not running traffic very high

The meshg resolution is never set higher than the installed mesh so that slider is not going to be 100%, ever unless someone comes out with 1m mesh.,... thats not going to be a reality for another 2-3 years, and, if someone did come out with 1m mesh FSX would take 1/2 hour or more to boot because of the calculations that must to take place at that resolution. General public systems are not ready for 1m mesh. It will be another 2 years before that will be playable

Thanks for the answers nick. I returned the vid card today and got my money back so no damage done  ;)

Right now i'm looking for a good cooling system (not water one because it's so complicated to install) because my 2 cards were overheating pretty fast. Any advice on that one?
