And SLI is working for u in SL and actually incrased performance. If so how sinc I have been trying to a year to get SLIimproving performance. I can get it working however the fps plummet dramatically.
-
What AA, AF and screen size are you running Mark? Is shadows and/or DOF enabled with those fps?
-
I joined Fisk in SL and side by side we compared fps. I have a GTX 460 and intel i7 930 overclocked. Even though we have similar systems and his video card is about 50% superior to mine my fps were 100-200% higher. We went thru everything it could be hardware bottleneck, viewer settings, heat issues etc. Last resort was he was going to try his other hard drive. Also his fps were so low when he changed to shadow mode he should have crashed but only lost 5 fps whereas I went from 60 fps to 9 fps. He's got some weird issue that is very hard to pin down. Not his conncetion which was over 30mb/sec. I know someone with a GTX 580 and they get 50% more performance than I do. Also Fisk runs BF3 very well so maybe some issue with the video drivers installation although I guess this was an issue with AMD also. It's definitely not a typical or common problem in his case.

SLI does work in fullscreen however...IT SUCKS....and GPU-Z did show each card sharing 50% of the load however fps....sucked. So yes the best single card you can get the better and you will be very happy. Saves you money and heat in the case plus you get excellent performance with the higher end cards. Haven't heard if a GTX 680 works in SL yet.
-
From your posting I assume you have one GTX 680 working for SL? How has the performance compared to what you previously had?
I have tried SLI with GTX 480's with no success. SLI works however the fps plummet HUGELY. I used a utility program that confirmed each video card was splitting the workload however I would drop from 100-200+fps down to 30 fps range. I tried every method out there. Your best best is to use your second video card to handle AA using the Nvidia Control Panel. being a new card the 680 may not even be recognized. Have to checked with GPU-Z to see what the workload is for the second card?
-
SLI will decrease your performance dramatically. In my case.
-
I read in forums no GPU is fast enough anyway to saturate 3.0 so u aren't losing anything. I think I saw a video review mentioned would be apllicable for SLI so both cards can run at 16x?
-
You are right apparently triple the amount of shaders the GTX 580 has but slower as they run at the GPU speed. It has 1536 shaders compared to my 336 on a GTX 460.
If I remember right o/c the shader clocks with MSI Afterburner on a 460 had no effect on fps so the slow down may be no issue. Have you seen the
? Supposedly originally produced with three 580's and a single GTX 680 can do the same. -
Do we know if a 680 runs SL yet? Someone told me they have a 7970 and are getting a blank screen.
550 Ti $119
GTX 580 is under $400 canadian but in the US $500-600 range and the same company NCIX. There are 3 brands of GTX 680 on the Canadian site for $510 but out of stock atm and plus 11% for taxes
NCIX does have a US site but the product available is different.

i saw a thread where someone was using a 7950 http://forums.guru3d.com/showthread.php?p=4286648#post4286648
Do you get the login screen with no problem? If so you can go into edit preferences and try to log in with Low Settings. maybe turn off VBO etc.
Or I believe you can make a game profile witht he software that came with your video card and maybe adjust settings there so it works? It's similar to Nvidia Control Panel and managing 3D programs settings individually. Let us know if anything works and if it's better.
-
Your graphics is a chip on the motherboard i assume. Woefully underpowered for SL at anything above Low Settings I think. You would need a discrete video card to run shadows and a good one at that. I suggest a desktop for SL if you don't need SL to be mobile. For shadows GTX 460 at minimum.
-
Did you try other viewers? Did you disble VBO in the viewer hardware settings? Even a GTX 690 may have issues too?
-
GTX 680 are on sale $500cdn plus taxes. http://ncix.com/search/?categoryid=0&q=gtx+680
Benchmarks look to be about 50% faster than the GTX 580
In my case an upgrade from a GTX 460 would be triple the fps I get now in Shadow Mode?
-
Looking at that chart my GTX 460 768 mb card is 2fps better than a GTX 580 in OpenGL however Chris' GTX 580 is about double the fps as my card when using shadows in ultra mode. So I have to assume running SL fast is a lot more than just about OpenGL performance. So a 580 is still better than a 460 in shadow mode, DOF and draw distance I assume and probably with large crowds of avatars. that being said a 460 runs SL VERY WELL.

I tried SLI for a year with GTX 460's. I NEVER saw any fps benefit and in fact it gears down to about 32 fps from 100-200 fps. I tried every manner of settings including the recommended fullscreen mode etc. Apparently SLI used to benefit but not now. Nvidia claims Secnd Life supports SLI which I guess it does since when I monitor the gpu performance each card oes indeed share the load however the fps plummet. Some still claim it is a benefit however those people are few and far between. Someone said you have to max everything out in the control panel however that is slower also so not sure if it works as a benefit for anyone these days since driver changes. I've had driver issues for th epast year so can't even install the newer Nvidia drivers since there seems to be a well documented issue for some cards. I get a update failed error so the 270 drivers are as high as I can go right now. Seems hardware is ahead of software. I'm assuming you can turn up the shadwo quality and still maintain decent fps. If I do so I go down to about 13 fps. 600 series should be interesting.
-
So I tested at 1280x1040 with 2x AA and shadows and got 70 fps. Enabled DOF and got 46-66. There is no way to move the viewer window anymore? I'm running two monitors in this test.
-
My results may not be common for my system specs. I use multiple partitioned hard drives and install the viewer and SL cache on a RAMdisk. So after tweaking the viewer from it's default settings I probably gain 50-100% more fps? I'm glad to see an upgrade to a 580 would be worth it. SLI works...your fps will go from 200 fps down to 32 fps but I assume that's not the result you are looking for :-). I tried for a year to get it to work better but no luck. And with a 580 Chris has shown you dont need SLI. That was a pretty good test I believe. I will try on a smaller monitor your size and post

Using the LL viewer 84 fps is impressive and a great benchmark comparison using your resolution of 1920x1080 I got 47 fps with AA enabled. Disabing AA was 49. A superclocked 763 mhz GTX 460 768mb and i7 930 overclocked to 3381 MHz. Singularity is about 75 however not sure where to enable ambient occlusion. Definitely a fast viewer. So a 580 double the performance in shadow mode and I assume when there is a lot of avatars on a SIM?
That would be another good test. So you have an AMD chip so someone could have a saving there over an Intel chip and use the saving for a GTX 570 when the price reduces when the new vid cards arrive?
-
Same test and same SIM but using LL Viewer at 1280x940
2x AA = 75 fps
AA disabled = 78 fps
16x AA = 75 fps
So AA seems to be no issue re: performance with my system on this SIM in shadow mode. the other test with the Singularity viewer was done with AA disabled.
-
With shadows disabled at that location I was getting 275 fps.

You didnt mention what aspect ratio which makes a huge difference in fps in shadow mode. So i chose what i think
you used which was 1280x 940 or there abouts. -
Is that chart correct? Seems to indicate a GTX 460 is superior to a GTX 580? And that the GTX 560 Ti is even more so?
-
I thought SL does not benefit (in fact is much slower) with SLI? I have tried multiple times for over a year to SLI with a benefit and as yet no success.
-
Have you run shadows or projected light on your AMD card? LL develops with Nvidia cards which in theory handle openGL much better. What we need is some benchmark tests with different cards.
you used which was 1280x 940 or there abouts.

Which video card is best for SL, AMD Radeon or nVidia GeForce?

Do multi-gpu cards benefit in Second Life? SLI does not appear to in my experience (apparently used to). Does using the one card in a multi-gpu card perform better than in dual gpu mode?
