Hi, just bought a new GTX 660ti to replace old GTX570, first app to run is Vegas 12 Pro to test the render, and…. takes longer than previous card… is that normal? Vegas does support GTX 660ti?

The new Nvidia Keppler cards (i.e. the 600 series) changed their architecture and divided the CUDA cores in to four banks. This change is rumored to be intentional in order to limit performance to specific SDK licensing. The effect of the architecture change for Vegas is this… only the first CUDA bank is recognized. Your 570 had 480 cores. Your 660ti has 1344 cores but Vegas only sees 336 of them which makes it a step down. Once again the rumor is that this was intentional meaning that we will not see a driver update that fixes this as it is not a “problem.”

Oh, thanks for the info, and any idea or rumor if Vegas will be compatible with Kepler architecture and work with the 4 banks?

Matt, that’s by far the best, simplest explanation about this situation us nVidia camp-followers have gotten ourselves embroiled with.
I landed on the GTX560ti as a result of listening to others and my PC builder. PLUS I didn’t think that the GTX6XXX series was even out back at the time I was specc-ing my present workhorse. And THAT has to have been more luck than judgement on my part.
If you could return the card, do so, and try out the 5XXXti series. If you can’t return it . . dunno . . .

OK, so I’ll try to back the gtx660ti to the store, and, maybe to still improve old gtx570, gtx 580 or gtx590 should work right? ’cause still 5xx? is that true? to try to change the 660ti for one of those?

Why are you even replacing your GTX 570? Is it giving you problems with Vegas Pro?

Hi, In fact, I can’t use CUDA acceleration eneabled in Options, cause Vegas Freezes the video and only audio works, and during render it hangs too, so, read here in this forum that disable CUDA acceleration will fix those problems, and that was the solution, so I wanted to change the card to get more CUDA cores and get CUDA Acceleration enabled in vegas. 🙁

OK, so you happen to have one of the few GeForce cards that work for most people so I would try and find out why it doesn’t work for you instead of buying a new card. Your NVIDIA GTX 570 is the card that Sony benchmarks with on their GPU Acceleration page. That suggests to me that your current GTX 570 should work flawlessly with Vegas Pro 12.0 because that’s the card that Sony tests with!
At this point it would be better to start a new thread and ask what drivers people are using for their GTX 570. I would name the thread something like “What drivers for GTX 570 work with Vegas Pro 12.0?” to attract GTX 570 owners (of which I’m not)

Well I know you are a Quadro user and the new 600 series was about to be an incredible beast. Would you spend 3 times on a Quadro if you can get a “gaming” card that just by the sheer nature of its design made the idea of Quadros obsolete? I agree with you that it is a pretty ballsy move to start such practices with hardware but software has done this for a decade now. It is not like Vegas Platinum took any less resources to make. In fact it takes more resources to repackage and diminish Pro to make Platinum. They can’t just reduce their price on Pro to get people to buy (there is sarcasm dripping from that sentence.) The idea that hardware developers are getting in to this practice by crippling performance without even making a show of removing actual hardware such as cache memory etc is troubling.
