Low fps!!!

[Snoopy]

Hi! I use the following "low price " configuration: Phenom II X4, 4G DDR3, 3xHD4550 + 1xHD4200 (integrated).
With 5 displays disabled i have about 80 fps (1600x240); with enabled displays my fps drops down about 12 fps (5x320x240).
I would like to use 7 displays (7x320x240) in the future and i can't imagine what would happened then: fps drops down to 5 fps?
Please help me. It's urgent!

There's a couple of things you can try:

Disable the 'global effect and blend modes' in the Video tab of the preferences. This gives you less options, but gives a performance boost for most people.

You don't mention which codec you're using, but DXV clips from an external SSD drive will give you best results.

Anyone else with other suggestions?

try to deactivate the onboard-graphics!
maybe there is a problem with the performance... for more outputs you can use a matrox... which is not really cheap, but a really good helper
and which OS do you use?
maybe another pci card would also do the job if possible, but mind that since vista there is no support for older cards, only hd2xxx upwards on xp it should work fine so far, i have an ati 9200 which does her job good but only on xp

Hi!
I tried 3 OS (Win7 32bit, Win7 64bit, XP), different drivers (now catalyst 10.3), different settings.
There was virtually no changes!!!
Help, who owns a Tip!

What codec are you using? Using DXV should give you quite a boost. Try re-encoding some of your clips in Quicktime DXV format, and see how it goes.

Without the clip, just a blank composition! The more active display, the less fps!

With 4 displays (blank composition, 640x480) MSI Afterburner hardware monitor shows 80-85 fps while Avenue has 15 fps at the same time.

Unfortunately musing multiple videocards is not the fastest solution to multiple screen setup. It's often faster to use a matrox tripple head to output to 3 screens that it is to use multiple videocards. This is because all the data needs to be transferred from one card to all the others and this is unfortunately not so fast.

i also had the experience when using a 4870 and a 4350 for extra outputs.
i will test if it's faster with a 4870 and 4670... the 4350 has only ddr2
where's the bottleneck between the cards? the memory should be a problem i think! or is it because the pci-e slot only runs @ x4 in my case!
it would also be interesting to use a crossfire bridge for such transfers, but i think it's not conceptec for this
and, is there a way to enhance the performance in newer versions?
