I installed VP 22 yesterday and tested it by rendering a project built with VP 21. I have been having issues with slow rendering under VP 21 build 315. VP 21 build 208 was much faster on my hardware. I was interested to see if VP 22 resolved this performance issue.
I found that the render performance was much improved over VP 21 B 315. However; I found that during render the memory usage grew slowly; eventually using all physical RAM. I found that if I let the render run on, my computer eventually crashed.
I repeated this with a different project and had the same result. I found that stopping the render did not release the excess RAM. Closing the project but not closing Vegas did release the excess RAM returning usage to around 38Gb.
My hardware in a Intel Notebook with Windows 11, a 12th gen i7 CPU, an ARC A730M GPU plus an Intel Iris Xe GPU. It has 64Gb of RAM installed.
Under normal conditions (VP 21) my computer used between 30 and 40Gb to run the OS plus Vegas. This usage usually remains steady during video render.
