Solved GPU Not Avaiable

I've been having troubles with Vegas Pro 12 trying to get it to recognize my GPU. I Have Nvida GeForce GTX960 Card. Windows manager says it there and operational. In Vegas in the preferences tab I can select it and when I try to render I select the "Custom Settings" and under "Encode Mode" I select "Render GPU if available". When I select the "Systems" tab and click on "Check GPU" I get "No GPU Available".
I hope it's something I've overlooked. My System is:
Windows 7 with an Intel i7-4790K CPU@4.00 GHz and 16 gig RAM. it's a 64 bit system.
Any ideas on what's the problem?

You might want to read the following SCS KB article.
GPU Acceleration explained

The last but one paragraph may have the answer.

Hi Robert,

Here is another article which may be of some help explaining it.

Video Cards for Vegas and Movie Studio

Thanks for the info. I was getting such quick renderings last year when i did a similar project. this year i've been having so much trouble. I finished the rendering of the 1 hour 22 minute play and now I'm trying again without the GPU and only set for the CPU. after 4 hours I have 4 hours to go. So, something has changed for sure. I was ready to format and start over. This is sure a strain on the brain. Were's my Amiga 2000 when I need it. probably in a dumpster somewhere.Guess I'll order the AMD GPU and see if that helps. I guess the Nvidia will make a nice doorstop.

Have you tried using drivers for certain NVIDIA GPUs (GeForce 337.88 or older) required for GPU-accelerated AVC rendering as advised in the SCS KB article linked above? You say you updated the card. Does that mean you are now using a later driver version than before?
