Hi Tugkan,
Not sure if I missed one of your setup points or there is a setup out
there you are still seeking. We are running a setup now that is starting
to fit the smarter, smaller, faster and cheaper doctrine that we have
all seen coming for some time. I think it took longer than some expected
but seems to be gushing now.
I currently run three windows/rendersurfaces/cameras on one display.
Three of my cores (dual, dual core cpus) are ticking along with what I
assume is the load from the separate cull/draw paired threads (although
I am not doing any explicit 'runon' or anything like that - not on
Windows anyway). The fourth core seems to idle along not doing too much
and available for extra stuff such as paging I would hope. While not the
Performer model there is what seams like a reasonable parallelisation
happening by default. At present I am also pushing this through an SLI
setup which does quite a good job of boosting the systems capabilities
over just one card and the drivers could do better still.
It's not perfect but it is off the shelf. Some form of
frame-syncing/locking would help as I just never go for 60hz. Genlocking
isn't an issue as its one display. I wouldn't also mind betting that if
I left a core idle that the frame balancing with SLI might even be more
efficient with two windows.

NVidia guys I've talked to said that a combiner hardware might
eventually be available. With its help two GPUs can render to one
display. It will be possible to open two windows on one monitor and let
them be rendered by two GPUs. Unfortunately,they said that this
development is 2-3 years away.
Are you sure you didn't mean SGI and 2-3 years 'ago'? If anything we
have more trouble splitting than combining but even that is seeing
adequate commodity solutions now.
It will be harder and harder to feed the GPUs with only one CPU because
nowadays they don't get faster much, instead their number increases so I
am trying find out what are the possibilities in OSG.
I'm thinking my next upgrade is to dual, dual gpus, running in quad SLI,
by the time the divers are really ready for that we'll be able to
install dual, quad core cpus. I don't thing I am finding the cpu a
bottleneck yet.
