Help with TripleScreen SLI setup

[AcesHigh]

With the help of AH Sid post of using ROF profile in Nvidia Spector I was able to double my frames from 12 to 24, much more playable now.   However, I'm seeing and have heard several of you with SLI rigs running triple screen getting much better performance.   Any idea on things I can change? Specs in SIG, I consider it a pretty high end machine.

 

 

- In Nvidia control panel have PhysX setting to auto detect, also tried forcing card 1

- Tried resolutions 3072x768 and 5760x1200 - no FPS change

- Tried low and maximum settings no FPS change between the two

- WIndow and Full screen mode same FPS

- In setting FPS limiter set to 60

- Installed latest Nvidia driver that came out today in fact - no FPS change

- Used AH Sid's trick mentioned above, doubled frame rate

- Not OC'ing process or gpu's

 

 

Some of you are getting 60fps with similar hardware or lower spec hardware, wondering what we have set differently.  Thanks in advance for any ideas.

Why not just hold off on sli for the moment and just run with one card? I have a 670 running at 5760x1080 and my framerate is phenomenal. In my experience, games in development stages usually aren't sli ready for a while.

I've added a bit to my other post, try that AcesHigh

I did not know one card could run a triple screen resolution.  In order to enable surround it requires both cards.   If your not running surround or eyefinity how do you get that high a resolution across all monitors?   In windows mode?

I'm running surround. Desktop is at 5760x1080 in spanning mode. The 600 series is the first Nvidia card that allows 3 screens on one card, I believe. 2 in the DVI ports, one in the hdmi.

 

BoS shows my range of resolutions, 1920x1080 through 5760x1080 and everything in between and less natively in the list, full-screen or windowed, just as any other game.

AbortedMan your not related to the disaster X Rebirth (EGOSOFT 4x Space Game)  in anyway are you .... hahahah, your explanation makes sense though, I don't have all mine plugged in the same card though, but may try that later and see how it works out.   I've heard running SLI can sometimes hurt performance in situations like this one.   Thanks for the tip 

 

AH SID Thanks again, I made those changes in startup and squeezed out a few more FPS.  Up to around 33-35 now, still looking for the magic fix but certainly much smoother.

As an ex sli user, may I suggest ditching the dual card setup for just a single beefy card. I found myself being more disappointed than anything when learning sli was less of a priority on the gaming development front and support regularly gets neglected due to sli configurations being the minority.

 

Everything is so much more streamline when you only have one card.

Just a little nuance I discovered...when running the game in 5760x1080 the aliasing is horrid, and the game looks as if it's being rendered through a lower resolution filter that makes everything blocky and "screen door"-ish looking, hard to explain...but changing the res to 4098x768 clears it right up and fixes most of the excessive aliasing problems.

 

It's weird to see that a lower resolution actually affords a more fine picture, but whatever works. If anyone is having issues with aliasing and big resolutions, kick it down a notch to 4098x768.

I don't think its the AA, its the aspect ratio still sitting at 16:9. Had the same problem with "another game" until I changed to a proper aspect ratio. That being said, I'm in the same boat as I don't have an option to do so in BoS.

Could you post a screenshot of what you're seeing? There's a common problem with RoF and BoS causing the image to be rendered internally at a very low resolution when post effects are enabled, but I think both handle the aspect ratio changes just fine. It would be interesting to see what you're seeing.
