Been beating up the AI-FX in the recent VP20 update. Style Transfer not only won't crash anymore, it's outperforming both Colorize and Upscale. So much that I had to update the older ai-fx test project I mentioned in this discussion of a Techgage Review. The review griped about the Vegas AI implementation. I'm calling the updated test project the AI Torture Test. I lengthened it from a 10-second media-length to 60 seconds. My original version was just running too quickly to compare performance of different machines. Too many things were running in under 10 seconds. If anyone wants to try the new version with the VP20 update, you can download it from here:
Ran the updated Torture Test on my relatively new laptop and a much older Intel NUC and threw the results into google sheets here: https://docs.google.com/spreadsheets/d/1oqSnW0U5mN16BAF3wGL0MwisWz_kY1Vf4HFfZ9Ie_ec/edit?usp=share_link
Looks like the default now is for Vegas to run AI stuff on the same gpu that is selected in Video Prefs. The activity shows up on my laptop's Nvidia and on my Nuc's AMD VegaM. If the Intel igpu is selected in Video Prefs, it runs like a dying dog. In older versions of Vegas, AI activity showed up on my Intel igpu where Style Transfer crashed allot. It's looking real good now on everything but Intel. And seems to love gobbling up Vram. But somehow manages to run, though not all that well, in the VegaM which only has 4gb Vram... grabbing it all. I imagine it'll run much better on a bigger gpu with a whole lot more Vram. I won't be at home base for a while, so someone else will have to check that out.
Btw, the Torture Test will run on VP19 but if Style Transfer is not disabled in Track FX, it'll probably crash. Same for VP20 build 214. The new VP20 update is pretty solid with it, however. Though I did instigate a crash once when I killed the render while it was running.
