I've compiled a spreadsheet of reports of "good" and "bad" NVIDIA drivers for Vegas.
It's a little simplistic because it doesn't take into account the operating system, the Vegas version, the other hardware, the symptoms of the problem, or various other variables. However it should be a good guide for which driver to try or advise others to try when thing go wrong.
Note that the same driver versions tend to fail or succeed across all the GPUs within one architecture. So for example, in general, what works for one Fermi card would probably work for them all, and what fails for one Kepler card would probably fail for them all.
If you have corrections to submit, or further reports of success or failure, please post the following information and I will add them to the spreadsheet:
- Graphics card model
- "Good" driver version if you've had success
- "Bad" driver version if you've had problems
- Symptoms of the problem
- Vegas Pro version
- Windows version
(You'll be able to find this post via the GPU FAQ post.)
