Dual GPU Cards - Anything new with V4?

[gregsully]

I'm marking the upgrade to V4 with a new system build. Does v4 take advantage of Dual GPU cards like the ATI 6990?

If not whats currently the top suggested card for a Resolume box build?

Does Resolume 4 support SLI?

The team has been busy, I assume .

What about multi-gpu? Is it implemented in Resolume4?

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?

I tested 3 Singel GPU graficcards in the past... and any of these cards made a great job with nearly none difference between.

Powercolor ATI HD6850 1GB = 120€
Gainward Nvidia GTX580 3GB = 460€ + No tearing when u disable Win Aero
ATI Firepro V8800 2GB = 1200€

Any extra info needed? ask!

i don't think that dual gpu cards are now supported in R4. Did'nt heard anything about.
The next problem is that dual gpu systems are not the best solution for a smooth playback (micro-stuttering - mikroruckler, btw. the discoverer of "mikroruckler" has died a month ago.... anyways)
It's like having a cluster, it can't be as stable as one machine

in future i think there will be dual gpu cores like in cpu's, but as long as they don't reach 2 or 3 ghz, there won't be any really use for dual gpu systems i think!

althought, it would be really nice. looking at a amd f1 system crossfired with an extra radeon hd6xxx series and you have a cheap and power saving system.

also a single test with amd f1 would be interesting. for single screen setups it should be enough i think, and future "apu's" will get interesting for small vj systems!

just to be clear (it confused me): AMDs new socket is called FM1 And yes, it sounds interesting. Haven't heard of it before. Thanks for that. But a SLI/Crossfire setup produces micro-stuttering as well, doesn't it?

yes sli/crossfire has the same problems... a one card solution should work better normally.
also you loose the outputs from the "slave" cards

but as i wrote i think as long as there are no cards with dual-gpu-core chips, there's no need for them
nvidia physx seems much more usefull in such a case i think. don't know the exactly behaviour with micro-stuttering but normally physx makes games really smoother and enables more effects. Especially for live particle animations this may make sense!
