I've been using Vegas for around 5 years. It's been amazing until the last couple of months where the software now has issues with "Not Responding", Refusing to play when I press Play/Spacebar, crashes, freezes and general lag. I used Vegas Pro 14 from 2016 - 2019, I started using Vegas Pro 15 late 2019 - Present. Both 14 and 15 seem to have the same exact performance problems as I stated above. I've tried many fixes such as lowering preview quality, changing Dynamic RAM, Turning certain setting to FALSE in the Internal section of options, turning off GPU Acceleration and more. I also wiped the hard drives of ALL Vegas and Sony software and folders. Yet, after a clean reinstall, the lag and crashes remain.
Need advice asap as this is my only source of income.
