In my Vegas pro 16 timeline I have an MP4/MP3 file (gameplay) and and MP3 file (my commentary). I don't face any problems with freezing or slowing down until I import my commentary, I guess it is because there is too much on the timeline? The problem I am facing is delays when I press my spacebar to watch the playback and if I move around the timeline too much the program will crash. I have to work at turtle speed in order to make the software run optimally.
I also recently upgraded my GPU in hopes to see improvements (I had it suggested to me that I do so from this forum) and did not.
My PC specs are
-Intel Core i5-7400
- NVIDIA GeForce 1650 (upgraded from a 960 recently)
- 500GB SSD / 2TB HDD
- 16GB DDR4 RAM
Any suggestion settings or adjustments, or even PC upgrades would be much appreciated.
