GPU Acceleration Problems Continue
I am using Vegas 11 build 521 64 bit. I continue to experience unacceptable rendering and previewing of videos when using the GPU acceleration option. I have upgraded my video card to a NVIDIA GeForce GTX570. I have set my dynamic ram to 512.
When using these settings, the video in the preview is very poor resolution, it goes from light to dark and then appears ok for a while and then returns to light dark and so on. The rendered copy is the same.
I then deactivated the GPU acceleration and restarted the computer and the problem was not evident. The rendered copy was good.
I contacted Sony about this when I first upgraded to 11, I sent them many files they requested, but they could not find a solution. I was hoping with the latest build (521) this would have been corrected, but it is not.
DOES ANYONE ELSE HAVE THIS PROBLEM???????? If so did you find a solution!

i believe this is a similar issue most people are experiencing. I too have an EVGA GTX570 HD 2.5GB card that is a dog with the new SVP11 64bit. I purchased the card specifically for SVP11’s gpu capabilities. All I read about is disabling the feature and move on. It’s not a fix, it’s a non-fix. However I then read about others having issues with Adobe’s software so… seems like it’s just a bad time in the video rendering world…

My problem rendering with Vegas Pro 64bit is that the AVCHD timeline imagery starts to color cycle in the Preview Window and this shows up in the final render also. During just normal playback the imagery in the Preview Window displays correctly.
In my case also, disabling GPU rendering results in a normal render.
My System:
Intel Quadcore Extreme
8GB RAM
Win 7 64 Ultimate
nVidia GTX 480 (1.5GB DDR5 VRAM)
Vegas Pro 64, Bld, 371 only (as the download update keeps coming across truncated so far). -
Do you think it is our video card? or are others with different cards having the same issue?

Set the dynamic ram preview to 256 or less. Play with it. There are weird issues with the dynamic ram preview setting.
Also, what happens when you “selectively pre-render video” and then watch it that way? Does everything come out ok?

Video card isn’t it, as my team also uses the AMD FirePro V4800 cards to render. Same issues. I’ve also seen the color effects, and had it appear with the default settings. I was at first convinced it had to deal with the rendered resolution we were using which was 1920×1200. At lower resolutions I had more varied success but ALWAYS got failures at this res. We have since disabled GPU rendering, but I’ve also re-imaged my workstation 3 times now. I’ve been changing vid cards back and forth between the V4800 and GTX570 with exact results. When utilizing 56GB of DDR3 1333MHZ RAM I’d say that the Dynamic Ram preview setting to 512mb is a waste. Setting it lower? Why? I’ve nearly maxed out this workstation for this program alone. The program stops seeing all the threads my machine has at 12 threads, but why skimp on the dynamic preview? I ought to be able to throw 4096MB in there and still have this machine fly… I’m about one more re-image away from heading back to SVP10. It’s really to the point of asking for my upgrade fees back, times 3…

Just the worthless upgrades we all did for better preview in SVP 11. I have a Radeon HD 6870 that was “supposed” to have 4x’s better preview. Whenever I have acceleration on, it is no better than without it AND I suffer from stuttering audio and other anomalies. I have another editing box with a GTX480 and same issue. After spending $ on upgrade and GPU’s I wasted a whole lot of time and money. In addition, if I am rendering in any AVCHD format, and forget to have it use only the CPU when rendering, I come back and see it will take days to complete a render. All this while running off an SSD main drive 16GB of RAM and a Hexacore AMD chip on the newest gigaabyte board and all drivers most recent…..in addition, I must make sure I save after any important edit as Vegas could crash at any time. I abhor editing more than one stream of video in Vegas, but do not have time or money to move to another platform, so I continue to pray Sony actually starts to fix these issues…..unhappy to say the least, and I REALLY LOVE editing in SVP….so many of us feel your pain!

At least I know that I am not suffering alone! Yes, it does seem quite a shame that we all spent money for the upgrade and many of us a new video card and for what appears to be just trouble. I have the acceleration turned off and will not use it until another fix is offered and then hopefully they will have this figured out. I would like to know who tested the beta on this and said it worked!
