Best settings for GTX 970

Hi,

I spent quite some time trying to find the right settings for Vegas Pro 18 trial to get stable renders for very simple timelines.

My system:

Vegas pro 18 trial build 373
Windows 10 (pretty fresh installation)
AMD Ryzen 7 1700
Nvidia GTX 970 drivers version 432.00

With a fresh Vegas install I was able to render the UHD clip. After Vegas stayed open for a while it was not possible to render anymore with various errors being thrown (not enough memory, component could not initialize). The only combination that seems to work well is:

Dynamic RAM preview set to 0
In the internal settings OpenCL/GL interop set to FALSE

Both are crucial to be able to render or prerended in a more or less stable fashion. I'm posting this as a tip for users with a similar setup and also to see if others have any better solutions. It'd be nice to be able to use the Dynamic preview function.

Thanks,
Daniel

What does vegas18 say when you use the driver update function in help menu?

I'm using 456.71 driver - works well

It turns out I had old drivers 432.00. I updated them and restarted my machine. It seems like the OpenCL/GL interop set to FALSE is not necessary anymore.

But if I build RAM preview and then try to render it fails with:

I've got 32GB of RAM, at least half of it is unused, Vegas only ever uses ca. 4GB.

Keep dynamic ram preview set at 0. If you need to preview parts of your project best to do a selection on the timeline and render to a file and then play that to see how it looks or compare to the preview window. also try setting the number of rendering threads equal to the number of CPU processors you have ( I have four with no hyperthreading so I set it to four, if I had hyperthreading I would set to 8). Vegas only uses max 50% of your ram. I never use Dynamic Ram preview as I can see the effect of transitions ect in the preview window in real time by using best Auto. Driver 457.09 is the latest game driver, I have not tried it yet.

I've got the rendering threads set to 16. I lowered it at some point and forgot about it.

I find the Dynamic RAM preview very helpful because the preview is jittery for me on some effects and transitions. But it looks like it needs to be set to 0 for some odd reason - likely a bug.

Thanks for your answers. It helps a lot after around 20 Vegas restarts and crashes :)

If it helps you, it is enough to set it during editing to a certain amount you need for your Dynamic RAM preview through Shift+B (amount depends on the lenght of your selected region) and at rendering only switch it to 0.

Yeah I might simply do that. Thanks!
