I've never had this issue before in any of the previous versions, but MS14 can't seem to handle playback well at all. It will run a single video track at full res just fine, however, if i try to add a second video track, any time i try to utilize the second video it just tanks the framerate for the video, the audio keeps running fine, but i'm forced to reduce down to Preview (Quarter) if i want to see the second track smoothly. But that isn't all that helpful as i kinda would like to see how it looks at 1080 BEFORE i render the final version.

Any thoughts or suggestions? And no, its not my hardware, unless i'm running the stuffs that are not supported...again, this is the only program, and the only version of this program that can't seem to handle anything more than 270p i've had on this system.

WIN 10 (not impressed so far btw)
