I've updated my post, it is possible, there just isn't much info out-here that directly correlates.

From what I have read there isn't a simple way to do so (but there is). Also, I've read the rendering engine of SL is apparently single threaded, therefore it doesn't matter if you have 1 or 4 GPU, it will still only utilize one core. Most of the time FPS dips, is when it's pulling data from the SL servers. Until we all have gigabit internet there will always be momentary hang/lag because SL is like 3D internet, each sim is like a 3D webpage, and like a webpage the content is dynamic, changing all the time. So it always has to pull new from the server. It's not like WoW where all the realm data is on your computer and the only thing being transmitted is Player and NPC data; in SL everything is being loaded all the time, though you could make your SL cache space bigger. The only time I ever have a hiccup is at the same time as something reading/writing to the drive, though an SSD would probably mostly fix that. I'm going to try some of these tricks for getting OpenGL apps to use multi-gpu that I found in this article linked below. Probably wont work, but we'll see. Of course it's good to have Afterburner OSD so you can see if the load is being distributed or not. The real shortcoming is that most applications "must" be in fullscreen mode to work in SLI/CFX and SL has no such setting. http://www.geeks3d.com/20101209/tips-how-to-enable-sli-and-crossfire-support-for-opengl-applications/ UPDATE: (next day from post date) So I loaded an other SL client, Phoenix Firestorm, which will run in Fullscreen, though I've also found that fullscreen is a little irrelevent, aside from making it so that GPUs can focus on one task. Irrelevent, as the CrossfireX seems to work in windowed mode with this app. I followed the advice in the tutorial linked above, and renamed the Firestorm executable(.exe) (not the shortcut,) to an app name that has a CrossfireX profile, oppened it and bob's-your-uncle, it works. Shows a bout a 50/50 load split per GPU load, everthing in graphics settings set to full 30+FPS. Best thing ever, I've never seen SL render this good before. If there isn't much happening on screen it even run up around 60fps. I haven't tried the file rename with the native SL viewer yet, but I will. :matte-motes-big-grin-squint: Also, another trick for boosting performance is to create a RAM disk and have it load the SL cache there, this of course is only plausible if you have 8Gb+ of RAM to start. You have to have enough to support your system, and it's SWAP file, and still run the RAM disk. This also extends the life of SSDs. There is a little article over that the Catnip SL viewer website on doing this, http://catznip.com/2013/02/23/speeding-up-sl-with-a-ramdisk/ Really great tips though. I hope this was all helpfull to anyone looking to CrossfireX or RAMDisk their SL viewer for (way) better performance. Another thing for bosting performance of the viewer that I found. Enlarging the downstream, Rx, Incoming NIC buffer. Some Network Interface Cards will let you change this in the device driver settings/properties, found in the Device Manager in Windows. It's rather small really, set to about 256Kb default on mine, I upped mine to 2,047Kb(max) aka 2Mb. Which may seem small, but in SL a lot of what you load is big stuff, so 2Mb is a huge differenc over 256Kb.

Version 2.5 to version 3.1 all within one year, don't give me that crap. I have all the problems many of have listed on here, on my desktop; which runs Windows Vista, Intel i7, 6Gb RAM tri-chanel, and two CrossFireX linked ASUS 6850 GPU with 2Gb of VRAM between the two of them. A 3D rendering powerhouse. However, on my MacBook Pro with 8Gb of RAM and only a Core 2 Duo and an Nvidia Mobile chip with only 256Mb of VRAM; it prioritizes my avetar over the environment. So even though everthing is loading around me, I still get a great frame rate on the Mac. While walking the lag meter claims my fps is 10-15 yet the walking is smooth, the rendering is smooth, and my avitar moves freely with the environment loading around it. The desktop is a different story all together, with the EXACT SAME SETTINGS on the client it says 10-15 fps, and you better belive it means it. Can't move, only a cloude for an avitar, claims there is network lag of 600ms. It takes several min to load all the textures inside my little SL house vs the 15sec it takes on the Mac. Why is there this HUGE disparity between my Mac, and the Desktop with Windows? I don't know, I have a 20Mbps internet serivice that is always great. I think if anything my desktop is WAY overpowered for this task so I'm going with CRAPY CODE. Obviously they are using a junky compiler, or missing something in the port to Windows. Or the code just sucks. Overall SL Client for windows blows hardcore and it shows. I think somebody is rushing development faster than the Windows coders can keep up with. Along with a probable destructive-pessimist in a high place clearing the realese of things that CLEARLY are not ready for release. Both have the same graphics settings, both bandwidths are maxed to 10Mbps. Yet one performs like a dream and one is an absolute NIGHTMARE! Something that can help on both though is to uncheck the box beside "Enable OpenGL Vertex Buffer Objects" Me>Prefrences>Graphics>Hardware. Also disabling anti Ailiasing, and Anisotropic filtering can help too.
