Vegas Pro 17 blows up every time as soon as I move any file of any type to the timeline. This is a brand new LG Gram laptop that I have had no problems with. i7, 16 of memory, 512 SSD, 2k screen.
When I read the title of Vegas blowing up, I really thought this post was going to be about telling us how he thought Vegas was THE BOMB! 😆
I haven't tried VP17 yet, still on VP16 so I can't share any personal experience. Alls, I know for certain is that working on a PC with so many pieces involved it's like walking on eggs and that's one of the reasons I keep a constant running log of changes, tweaks, and installs that I've made along with notes of where along that constant running list I made a HDD image backup. That way if an install ever goes amuck or anything else, it's always pretty simple getting back to a point prior to that install and things going amuck.
The only thing I can suggest is to see if there are any potential problems under the hood of your system. Having a brand new laptop doesn't mean squat, and if anything that could be part of the problem since often drivers are shipped with a new laptop and fixes with updates to those drivers come out afterwards and without those driver fixes in place, things like you're experiencing with VP17 tend to happen.
I find the website linked below as a tool, to be really useful. It requires installing a small app to run a simple system benchmark performance test. What it does is that it runs a performance test benchmark on each of your hardware devices, and the overall system and then it posts a web page for you with the overall results and the individual results of each piece of hardware and it compares those results with thousands of others who have that exact same hardware, so you can see how your hardware is comparing to everyone else with that same hardware. Those results can be bookmarked, so that when you make any updates or changes to your system, you can run another test to see which direction your result went and then compare them to the prior results. I often find, that if a particular piece of hardware is running slower than everyone else with that same hardware, then that usually points to a potential problem where a driver, firmware or some other setting related to that device needs to be updated. It can help point you in the direction of solving your problem.
