I had Movie Studio 2018. It was taking about 3 minutes to render a 1 min video using MPEG-4 under the 'Best' quality. About two weeks ago I upgraded to MS24 and was pleased to see that rendering was completed in 30 seconds or less with hardware encoding. Now, just about 10 days later, MS24 has reverted to taking 3 minutes to render and is stating (in the Mixdown window) that I need to update my graphics drivers. I verified that my NVIDIA drivers are indeed up to date, but that did not help. Is there something else I need to do?
