Previous versions had a Constant Quality (QP) option on NVencoding, but it's now gone in v18, why? This is my single most important rendering requirment.
If you use Voukoder (or HappyOtterScripts) you can set the quantizer value as shown here. While earlier versions of Vegas (V15-V17) had this as an option as you have indicated, there was never a way to actually adjust it, which may be why it is not shown in V18.

Will give that a try, thanks. I would use Handbrake but I always had problem with the Vega integration of that. Still doesn't explain why they seem to have removed the feature entirely in v18 though?
Are you actually using Nvenc via voukoder?, you have to select the option via the menus
I had a look at your YT channel and I notice you only upload in 1080P, however you may edit in 4K, but render out a 1080P. Voukoder will render at your project resolution so this could also be a reason for the slowness if you are sure it was using Nvenc. In filters/ zscale you can add for 1080P resolution
Thanks everyone. I goofed and had the CPU version selected. NVENC x264 selected and it's now indeed faster than the Vegas NVenc QP Unfortunately the file size is bigger than the VBR version, where the QP Vegas version used to be much smaller. I have QF23 set, and it's 1080p project so its should be smaller than normal 8Mbit minimum VBR. I need to experiment further, will pull in an older v16 or v17 project and compare renders.
