Thanks for showing your preferences. I can see this is not the current version of VP 21. Please download the latest build and test it again.

Can you share MediaInfo for your file? https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

First comment- as this is over 4K VEGAS automatically makes a proxy file, so if you're not say at best/full you won't be seeing the original file and there won't be any GPU decoding for the proxy. Without the proxy file I get GPU decoding activity with my Intel iGPU. With NVIDIA you likely need the new build of VEGAS Pro 21.

Second, is this a conversion? Variable framerate 10-bit HDR10 HEVC isn't an ideal editing format for VEGAS.

As an fyi, with creation of Vegas automatic proxy files enabled, all of the Best and Good preview settings bypass actually using them. I usually use Preview-Auto or Preview-Full when playing which look pretty nice with 4k hevc proxies and only switch to Best-Full to play short sections for selective pre-renders or dynamic ram previews. If Preview-Full or -Auto don't perform well enough, cutting the project frame-rate in half or by a quarter can help some more... that doesn't automatically go back when rendering so don't forget to restore the project frame-rate once editing is done.

Also, if you update and you don't have an Intel igpu, which I'm guessing you don't if auto-igpu is selecting Nvidia, try out both checking and unchecking experimental-hevc. Checking it might be a quicker performer, similar to unchecking legacy-hevc in the older vp21 as you've been doing. But developers mentioned not being totally satisfied with it's stability, so save your work before rendering. If performance unchecking experimental-hevc is acceptable, that's recommended. And report your experiences after update.
