the gtx590 / ati 6990 are dual gpu cards, won't bring more performance cause there is no support for multi-gpu's.

don't know exactly which i7, i think it's a 1366 socket.
just used a normal hdd, but as i wrote it won't matter if i play no footage or 5 layers, always same framerates!
the bottleneck should'nt be the harddrive, it's the graphics memory i guess!

Oh,
I've made another experience.
Before I had a SSD Vertex 3 drive...I used a normal HDD with 5400RPM with the same components (look in my signature)..
Without the SSD Drive I only can play a handfull of DXV clips....but now... see my result in post No.1

Ah..u're right..I just forgot it...
@Resolume: Will multi GPU be supported in R4?

i know that the harddrive is a bottleneck... but i play no footage at all and the framerate is still down....
so at extreme multi-screen setups there is a bottleneck before the hdd/effect/clip processing

just did new testings with my system (amd phenom x4, 2x2gb ddr3 1600, nvidia gtx285 plus 9600gt+9600gso+matrox triple head on the gtx285)
testing with up to 7 screens @ 1024x768
about 50 fps with 1-3 layers...
with over 10 layers and effects i get under 25 fps
resolume resolution was 3072x1536

i'm very impressed from the performance... we don't get better results on a new hd6970 with 2dvi and 4 display port (and 2 tripleheads). (system was an core i7 also with ddr3 memory)

so my suggestion is the memory interface... which is 512 bit at the gtx285 vs. "only" 256bit @ ati 6970.

newer nvidia models also "just" have 384 bit interface.

and as what i've heard the memory performance is very important.

so what impressed me that the "old" gtx285 nearly outperforms the 6970 in resolume.
also interesting that nvidia seems to get better results when using more graphic cards than ati!

also interesting... the ati performed better if we set the displays down from 1024x768 to 800x600 or even 640x480. The Nvidia card didn't "minded" if the resolution was 640x480 or 1024x768 per screen!

hope my suggestions is right and would be happy from a feedback from the resolume team.

@HerrNieDa:
It would be also important to know what kind of SSD or HDD you used in your tests.
....and...what kind of codec?

the test with the 6970 just run on a single 300gb hdd in our test system.
the gtx runs with seagate momentus xt (hybrid) as system drive and 2x1tb wd caviar black raid0 for clips

but it doesn't change the performance....
the 6970 gave out the same fps with no clip played and with 3 or 5 layers full hd clips and changed fps more through scaling the output via windows.

at the tests with the gtx285 we only had to use the matrox drivers for screen configuring in windows.

also be sure always deactivate vsync and anti anilaising in your video 3d settings (or create a resolume profile)!

codec was dxv, clips @1080p or 2400x600
also tested flash files which brought the cpu up to 50% usage, but not more...
without flash i never get over 35% or so (phenom x4 910e @ 4x 3,2ghz)

so, just configured my system that it now helds:
gtx 285, 9600gt, 9600gso and 9500gt together...
(the most i like on the system, all cards have tv-out :p)

and with a second triplehead i can test up to 11 output screens...
only problem is the amount of proper screens for proper testing

i'll report new results here

Sounds like a "Daniel Düsentrieb" creation! NIZE!
Can u post a picture of your computeranathomy?

Avenue 3 only adresses 1 core. that's why it won't go any further.

I'm not quite sure what you're asking exactly. Resolume 3 has always been able to utilize more than one GPU. We do advise to use a single card with multiple outputs or a Matrox 2Go solution, because this means the GPUs don't have to swap textures back and forth. But it's always worked and this hasn't changed for Res 4. But maybe I misunderstand the question?

Does he advise not to use multi-GPU cards or just not to use sli/crossfire setups?

normal the performance is better with a single card attached with matrox for more outputs.
with ati cards this is the case, but with nvidia it seems to work much better!

And what i've read resolume uses more than 1 core, also windows does...
(its a quad core cpu, so 50% should mean that 2 cores are "fully loaded"
maybe flash itself just uses one core, but performance was very good!

crossfire/sli is not supported by resolume and my system also would just be able to sli 2 9600 or i can activate physix (which can be activated, did'nt feel any differences, but also is't used by resolume i think)
