Hey everyone. Just reposting this as I'd originally put it in the wrong forum. So, new Windows 10 install on an i7 4700 MQ, 12GB RAM and a GeForce GT740m. Latest version of Movie Studio 15. I'm doing screen captures from OBS, using the h264 encoder in an MP4 with two audio streams; one for voiceover, and one for audio captured from another source.
The problem is that Vegas is using absurd amounts of CPU while previewing, even in draft half or quarter; up to 100%. The playback also alternates wildly between smooth and less than 1fps, and the program frequently hangs while doing things like starting playback, resizing or moving events, etc. It's not a full crash...I just have to walk away and do something for like a minute and then it comes back.
Something's definitely amiss here. I did think at first that it was due to me recording using the streaming codec from OBS, but I've since changed it to NVENC and there's no improvement. I've got GPU acceleration on, and I've tried switching the actual app between the nVidia and Intel HD graphics. Nothing seems to help. I'm not sure where the fault lies. It might be some video setting I'm unaware of (it's not my forte) or it might be something else. Any help at all would be amazing! Thank you.
