OK...I haven't used track envelopes before but opened up my V18 manual pdf and was able to add both video and audio track envelopes (in V21), add points to them, and verified their function in the preview window by playing the clip.
For grins, I tried my Stereoscopic 3D mode change test and it still fails.
Thanks for confirming there isn't an issue with envelopes (which are useful tools by the way!) and that Fx are broadly affected. Hopefully NVIDIA responds.
I've used something similar for time variable masking in Pan/Crop.
Vegas has been a learn by doing experience for me. I often try things I read about in the forum to learn something and/or see if I can help. (I spent several years as an apps engineer for a software company...)
In the meantime, there is another game Ready Driver 537.34.
Has anybody tried this driver
Works as well as 537.13... fx and preview while rendering fixed. But 422 banding still there in 32-bit projects
In the render processes, 537.13 generated artefacts here. That is why I am not sure if I will try it.
I looked what has been changed and after reading this as only changes::
"Game Ready for Mortal Kombat 1
This new Game Ready Driver provides the best gaming experience for the latest new games supporting DLSS 2 technology including Mortal Kombat 1 and Lies of P.
Fixed Gaming Bugs
[Starfield] Profile updated for Microsoft Store/Xbox Game Pass version [4266797]
[Counter-Strike: Global Offensive] black screen when using the GeForce Experience In-Game Overlay [4257572]
I did not try.
@j-v It is always interesting to read the the full NVIDEA release notes, looking at game ready 537.34:
Reading a bit further in the "Open Issues in Version 537.34" :
For notebook computers, issues can be system-specific and may not be seen on your particular notebook.
also: > [DaVinci Resolve] This driver implements a fix for creative application stability issues seen during heavy memory usage. We’ve observed some situations where this fix has resulted in performance degradation when running DaVinci Resolve. This will be addressed in an upcoming driver release. [4172676]
@VEGASDerek: Any news on your end? The recommended driver isn't working for me, shall I go back down the "compatibility mode" path?
Today I saw a new Studio driver that also works without that preview problem.
It is this driver
Confirm. Nvidia 537.42 Studio (2023/08/21) driver appears to solve the preview with effects, preview while rendering and grid display issues/bugs in Vegas Pro 20.
Installation was "Custom" with "Clean Installation" selected.
Tested with: Laptop, Windows 10 22H2, Nvidia 3070 Mobile wt Intel GPU hybrid configuration.
I just tried the latest studio driver but the preview didn't work with my GTX 1050 mobile.
