Your best bet is going to be to download the demo and see for yourself, as it may or may not perform better based on your hardware configuration and the types of video formats you edit. It does have a new video engine and does perform better with many formats, but your mileage may vary.
Like the black program menu bars but current version (302) is much slower than 21 or 22 when using stills and pan/crop effect. Hope a fix in coming soon (version 356 did not fix it).
I dual-boot and can run both or either, (within the limits of project versions). I'm currently still starting all my projects in 22. I don't crank out a video every day like many people have to do.
I continue to use 22. VP-23 rendering is slower, the preview is not smooth with same v22 settings (at least on my PCs) and legacy text titles are way off center. I do not like the redesigned render UI either. There are few UI changes I do like though. Try out the trial version as was stated,.. you may like v23.
I just upgraded to 22 a year ago. Is 23 much better than 22? Faster?
Renderings with NVENC supported templates are faster, in VP22 a small 2 min testproject with 4k50 HEVC footage renders to 4k50 HEVC with an average of 37 fps and in VP23 this project renders to 4k50 HEVC with an average of 53 fps. As @fr0sty advised, it's best to find out yourself with a trial version of VP23 the pros and cons, since the performance of VP23 relies very on used hardware and used video formats.
