Arena : Really low FPS with intensive mapping

[homing]

Hey, i'm having a real performance problem with arena with some intense mapping on multiples graphics cards. I'm running between 9 and 12 FPS

My machine is quite performant, running on windows 7 64bit
CPU : Intel Core i3 a 3.30GHz
Ram : 8 GB

Graphics card :
1 basic Asus graphic card , just to run the interface of resolume
2x GeForce GTX 660 Ti (4gb of ram per card) using both output of each card (total 4 signal)


The mapping is done trough the playback of a 1280x800 clip encoded in DXV (half the resolution of the 4 projectors combined )

There's probably around a hundred sliced, most of them with few step of mesh point, it's a pretty complex mapping.

What's strange is that even if i check the windows ressoures meter when resolume is running at 12 FPS, the CPU is running at 10% and only 1,85 gb of ram (out of 8) is used.

I've tried disabling global effects and blending modes, not much of a difference.

I think i've read somewhere that GPU acceleration is done only on the graphic card that is running the interface ?! is that true ? Then what is the option for doing some intensive mapping with multiples output ? Using a triplehead to go ? I'll still be missing an ouput. i'm kinda stuck here, it does'nt seams like a problem an hardware upgrade could fix.


Thanks

Resolume uses the GUI video card to handle everything and simply passes the texture to the other cards with a performance hit. You're literally using zero of the gtx 660's processing power and negatively effecting you under powered cards performance. Also if your asus card is an ati that's gonna fuxk things up real good.

Swap over the main card to the gtx 660 and I bet you life gets better. If your getting 12fps you should be pulling out video cards and upgrading to an i7. What's the point of tonnes of outputs when your output looks like stop motion?

Thanks
i'll try that, and let you know the result

That really helped a ton, thanks !!
