The thing is that Microsoft promises performance upgrades to both DirectDraw (2D) and Direct3D (3D) with that buggy update… the facts being is an update necessary for their new version of Internet Explorer (10) to run properly… and not getting close to other browsers performance and security such as Chrome, breaking DirectX stability for a large number of GPU drivers and software in the mean time, what a way to cause headaches to your customers, a lot of users are still clueless as to why their computers and/or software are not performing well and crashing these last few days…
Microsoft didn’t even sent a new update to fix the buggy one, thy just instead moved it from “important” to “optional”… come on, this is too much… almost as Nvidia breaking CUDA and OpenCL backwards compatibility with their Kepler Gaming cards and intentionally removing crippling their performance in GPGPU, but that’s understandable since they’re aiming at gamers and they perform extremely well for that, gaming, they expect you to buy Quadro cards for other tasks apart from gaming.

just a quick Google will neat you users affected with common desktop builds, CPU + GPU not hybrid, I updated some old computer lying about at home and tested… yes, crash with some apps even Vegas 11 + Nvidia 9800 GTX GPU, updated = crash when using GPU, uninstalled update = running back fine…. thanks God for manual updates and waiting for feedback before downloading any of them.

have you updated your VGA drivers recently? maybe the set you’re using now is buggy with Vegas, try rolling back to the version you were using when Vegas was running fine, if you didn’t update then it could be damaged system Vegas files or driver files, I’d try a fresh re-install of the OS with the on-board VGA disabled, updated Radeon drivers and latest Vegas built, you know sometimes the OS registry gets messed up.

I contacted Sony Spain and the Creative Software support told me it could be a bug on Windows 7 x64 Ultimate Service Pack 1 (even if it has been recently re-installed and fully updated) not “seeing” all that RAM and that I should try removing some sticks from the workstation and test with “just” 32 GB… oh well, I’m gonna miss that huge RAM Disk of mine if Vegas Pro 12 works better with 32 GB than 64… I’ll post results. Thanks.
edit: maybe the problem is the RAM Disk itself? fooling Sony Vegas into guessing wrong the RAM available when there’s 32 GB reserved for the virtual disk ?

thanks Stephen, yes I know what Dymanic RAM is for, I think I didn’t make myself clear my question is why is Vegas showing maximum value as the total VRAM installed in the VGA instead of the main system RAM (64 GB at my workplace).
Thanks for reading : )

On a side note, I think it’s important to say that other hosts such as NEWBLUE FX Titler Pro v2 (OFX 64 Bit plugin for Vegas) DO WORK with the Kepler gaming-oriented VGA’s and with the 660 Ti 3 GB it fills the VRAM to the limit and all CUDA shaders run at 99-100% as read in GPU-Z monitoring tool, rendering speed is blistering fast, twice as fast as that of my GTX 570 and 5 times faster than only using the Intel 3570K CPU…
So with the bad news and the good news the final point is that Kepler is not bad at all at computing, early benchmarks are done with unoptimized software so people think the 600 series is bad at computing… the truth being it only needs software and drivers designed to work with the radical new architecture separated from the good old Fermi.
As I said it’s all up to third parties since Nvidia won’t put their gaming cards against the Quadro cards even if they can get the job done great as shown in optimised software such Titler Pro v2, DirectX 11 Shaders Compute API, or the famous Folding@Home distributed computing software. Here’s hoping for Vegas Pro 13 with full GTX 600 series optimization. Credit where it’s due.

scratch what I said about Vegas Pro 12 and the GTX 660 Ti (Kepler), with further use of that PC build I noticed that Vegas Pro 12 doesn’t properly recognize the 660 Ti and won’t push its full VRAM for previewing nor its CUDA shaders for rendering, making it useless for editing purposes…
I’m sorry I didn’t fully test all my projects and templates before commenting on the Kepler card, it’s clear that both NVIDIA and Sony must provide support for the non-Quadro Kepler family of VGA cards to run as they should in Vegas, I fear Nvidia is not interested at all in doing so (hurting Quadro sales) so it’s all up to Sony… ah well.

I would suggest uninstalling your 6870 completely, even pulling it out of the PCI-E port, then starting Vegas in default mode (CTRL+SHIFT while booting) and see whether the motherboard’ built-in GPU is enabled in preferences->video, it it’s then disable it both in Sony Vegas and if possible in the PC BIOS, uninstall its drivers too, after all this put your 6870 back in your PC and install the latest drivers, restart your OS and try booting VEGAS, should work.
of course I’m assuming the GPU is well-powered, not damaged, using latest drivers and not overclocked (same for the CPU, some software is more sensitive to overclocking than other depending on the hardware), also assuming Vegas 12 is original software as well as the OS. Good Luck !

Hi guys, I’m using Vegas Pro 12 build 486 with Windows 7 64 Ultimate SP1 and today performed a test with a friend’s 660 Ti… a template that takes me 10 minutes to render at full 1080p with and old GTX 260 took only 3 minutes with the 660 Ti (Kepler architecture) even if only 25% of the CUDA cores are being used as shown in GPU-Z monitoring tool, the 660 Ti GPU activity is way lower than that of the 260 while rendering… but definitely it’s an improvement and had no issues with it using some other random projects and templates, I’m on the latest Nvidia beta drivers 314.14 and Dynamic preview RAM is set to 150 even if it says 3072 MB available (Gigabyte 660 Ti 3GB model).
I guess it’s a matter of time that both Sony and Nvidia provide the updates/drivers necessary for Vegas Pro 12 to take advantage of these increasingly popular cards, they’re very powerful and would benefit sales of both said cards and Sony Vegas, I’m sure they’re at it.
Well that’s all, cheers !
