I have looked over posts on these threads here and no matter what you do, Vegas 18 Pro refuses to use a GPU. I feel like these developers of the application did nothing by lie to users. I even saw one person say they resolved the issue by moving to Vegas 19. (Vegas is really a scam?)
I have all settings set accordingly but my CPU does all the leg work while my 4090 sits at 8%.
Please be honest: is the Vegas GPU Rendering really a scam?
