kind of an answer, but also a hi-Jacking.
I have the AMD FX 8350 with an Nvidia GTX 970, and 16 gb ram.. Sony vegas runs horribly on it. Cant get a smooth preview at all (draft quarters). The program bogs down and freezes, etc. Makes editing almost impossible
Ive watched every tutorial on how to adjust vegas pro settings for a smoother experience, and after all the setting adjustments, the improvements is little to none.
That said, its PC's, right? I could have an issue somewhere else. Games run ok. Though I do get a Display driver error alot during game play. so... who knows
