Sli support

[master9716]

I got 2 8800gts "Same speed as ATi 5850 "!!!!! @ high resolutions or
resolutions that we should all play at.

I tryed everthing to make Dolphin take advantage of both cards
using high Antilising settings but no success.

I can run most games @ 60fps with 2.5x SsA and I5 750 cpu.
but @ 4 atilizing my fps die out @ 1600x resolutions.


Would really love to see Sli Support for my baby.

Thanks Devs.

dolphin doesn't have sli support.... you can only use one graphicscard....

yup,not gonna see sli or crossfire happen.
i sold my ati 3870x2 and bought one 4870 :-)

not even close

Actually at high resolutions dual 8800GTS can outperform a GTX 460 by up to 1/3 if sli is being used properly.

Yes at 1920x1080 resolutions wich is what I play on my 50 Lcd 1080p . dual 8800gts or 9800ts or a single 9800gx2 is faster than a 460gtx and as fast as a 300 dollar AT 5850 ..even with max anilising.

I posted an add to sell my 8800gt slis for 140 and I took it down today bc its an awfull move to make.

In other words I have a ati 5850 videocard

Dolphin isn't very gpu-intensive, it's the cpu that's bottlenecking it, even though it's AA that's killing fps in your case. SLI/Crossfire support won't happen simply because most recent med-end cards are already overkill.

8800GT itself is good enough without AA...

Lol, my video card can't handle 9X AA :p. (I'm still wondering why).

Because your using SSAA. So your basically rendering at 9 times the resolution then downscaling to your screen resolution. So let's say your running a game at 1920 x 1080. Each frame is 2 mp (megapixels) in resolution. Let's say your gpu is capable of rendering 180 mp per second. That means you can render 90 fps at this resolution (180 mp/s / 2mp per frame = 90 fps). Now add 9xSSAA (triple width, triple height, 3x3=9x). Each frame is now 9 times the resolution since you've tripled the width and height, 18mp. So once again let's do the math (180 mp/s / 18mp per frame = 10 fps). Your down from 90 fps to 10 fps. So as you can see you need a VERY powerful gpu to handle that without any slowdowns.

it may come one day. just not any time soon.
