How many users have SLI/Crossfire?

[JG52Krupi]

What dx10 profile are you using?

I am using twoworlds2.exe and get pretty much 60fps (v sync enabled) everywhere.

Cheers

I have steady FPS from 45 to 60+

On the new GTX6804GB Card no need for SLI any-more.

I only get launchers when I press the F12 for steam screen shots,
I run Fraps with no issues,
I have had no launchers since this upgraded to this large of vram for the Video card.

Before the 6970 in use now, I used to have 2X 4890's in CF... due problems with ClOD I dropped them.

I have been running at default settings and tried AFR & 1X1 ,none realy made a difference but I shall give the twoworlds2.exe profile a try and see if there is any improvement.Thanks

Profile setup for the game, cards use those settings when launched in 3d.

I have 'used' SLI for years and my personnal verdict is: it generally doesn't work.

If it did, it would almost double every FPS of every supported game and honestly, I have never seen that other than with a special indicator in ROF...And without the indicator, I would not have noticed...so that's hardly double the speed.

And I have all the good (real) flight sims...

Also you buy twice the memory but you don't get it, each card needs to hold the same thing in memory.

If one day I want 3 screens, I'll buy 3 cards and link the desktops, no need for SLI here either.

In short, buy a good almost top of the line card that would have cost the same as two crappy cards and sleep tight.

My two cents.

PS: What kind of experience do you have with other programs and SLI/Crossfire ?

Not true. SLI works if it is supported by the game. I generally get up to 50% boost. If you get nothing you are probably playing sims that do not support it (FSX, BMS, and older ones do not, RoF and DCS does work). If thesims you have do support it, then you must be doing something wrong (Its not turned on or your bridge is loose or something).

True about the memory.

I tested in Default X-Fire with medium settings grass and roads on ,shadows off 87fps vs off ,69fps vs on.
Default X-Fire with V-High settings grass and roads on ,shadows off 45fps vs off ,46fps vs on.
Two Worlds 2 DX10.exe X-Fire with medium settings grass and roads on,shadows off 85fps vs off ,65fps vs on.
Two Worlds 2 DX10.exe X-Fire with V-High settings grass and roads on,shadows off 52fps vs off ,55fps vs on.
Lower altitude settings produce hesitations on all tests but slightly less annoying in medium settings.The rendering looked better in the Two Worlds profile.

@luisv
I started ROF with a single 5870 and when SLI/XFire was enabled got a second one .Performance went up by 50% easily so I upped the eye candy setting and got a nice balance .When I upgraded to a single 7970 the performance improved probably due to the extra memory.Adding a second card allowed me to max out all settings other than Anti-Ailiasing which is always left at 2x as thats the real frame killer.A recent AMD Driver updat introduced flicker of the clouds so I had to cut points of light from max to 15 but otherwise it runs as smooth as silk.

SLI / Crossfire is not worth it. First you have to buy two or three cards, a good cooling solution. Then after a couple of years when you want to upgrade you have to buy two / three new cards again. It is like multiplying the costs.
And very few games support sli / crossfire and does who do it is barely any difference at all. Some give you maybe 5 or 10 fps more.
