I prerender my videos pretty regularly and clear my prerendered files constantly. However, when I prerender as of late, it no longer plays back smoothly. It's choppy and it's like I never prerendered the selected area in the first place. I use Windows 10 and I'm not aware of any changes in my software since my prerendered files began running like this. I have plenty of space for my prerendered files as well, so I'm not sure what could be causing this. Any solutions?
