OT: GTX 680 is here!

Rumor has it that the Nvidia GTX 680 will hit the shelves this week. It is supposed to have 1536 CUDA cores compared to the 512 CUDA cores of the popular GTX 580! This could mean that the GTX 680 is 2X to 3X faster at GPU rendering compared to the GTX 580. Although V11.595 has not been running stable-enough for me to start using it everyday, PPro & After Effects will benefit and hopefully Vegas will too when (if) they finish fixing V11.

So.... Post your results if you happen to snag a GTX 680 earlier than the rest of us. I have been holding-off on buying GPUs for so long my current GPUs have cycled through two CPU & motherboard upgrades! Time to upgrade - especially since the fans are old & getting quite loud...

Good luck with the 7970. I tried it and had zero luck with it. I had to return the card to the store.

Oh really? Thanks for the head's up. I see older video cards listed here, but it would be a good idea for Sony to do a new benchmark test: http://www.sonycreativesoftware.com/vegaspro/gpuacceleration

I'm at a loss as to what to get, other than one of these listed GPU's. Is this an issue with Vegas not supporting newer video cards? Both problematic GPU's mentioned are PCIe 3.0. Hmmm.

Personally, I think it's partly Sony trying to accomplish too much at once. Instead of sticking with what works for everybody else (programming for the NVidia CUDA cores), the company tried to reach a broader market by using OpenCL which can be used with both NVidia and AMD cards.

The problem is that by trying to reach a wider range of cards, Sony also bought itself a huger plate of problems. There are compabilities problems galore. Sony wants to be everything to everybody but that is a vert lofty goal as far as I am concerned.

It would have been wiser to limit its support to certain cards and just those cards. Anybody who had any other video card would have had to use Vegas without GPU support. It would have been a pain in the ass but at least we would have known which cards were supported and purchased the right product accordingly.

Instead, we have no idea which cards work well. We have to rely on each other's experience.

From my own experience, I can tell you that the EVGA 2.5 gig GTX570 and the Gigabyte GTX580 SOC have both worked fine for me. The Gigabyte has obviously proven by far to be the best of the two.

Perhaps my memory is failing but I seem to recall being at NAB 2004 or 2005 and seeing a Sony/AMD demo of "Madagascar." That relationship may still exist and that could be the reason for the OpenCL in VP11. Or at least part of the reason instead of going solely with nVidia.

Got the GTX 670 working. There are a couple of issues here:

1. Main Concept MP4 converting WILL ONLY WORK using CPU (not GPU).
2. Compressed HD format AVCHD (even though co-developed by Sony) appears to lose audio synch when previewed at full resolution. Additionally it's a bit laggy.

This may be a driver/codec issue. I'm no expert, so I can't say for sure. At any rate, if you export video to a format, like AVI, the preview can handle full resolution playback. I'm sure it's a matter of Sony updating the software to handle this better. Surely this GPU can handle some pretty heavy lifting.

OK, so it's not just me. Hopefully nVidia driver updates will improve performance and fix the rendering/sync issues.

Living on the bleeding edge is SO much fun!
