So when I render a singular video, it renders at a regular speed. But then when I do a batch render, it's really slow. This wasn't happening before. Previous batch renders have went fine, but then one day they got really slow, and I have absolutely no idea why. I didn't make any changes in Vegas, and I didn't make any changes to my computer, hardware or software. The only thing I can think of is a Windows 10 update. This seems to be a very rare issue as I haven't found anything that would help me solve my case.
