Just upgraded to Vegas Pro 15. The lag time in the preview window is so slow it skips clips because it simply cannot keep up. It took about 8 hours to create a 90 second video because I couldn't watch in real time.
Windows 7 Professional, Intel Xeon 2.80 GHz quad core processor, 64-bit operating system, 64GB RAM, NVIDIA Quadro P4000, 4 hard drives - 3 are 4 TB.
There is plenty of power and plenty of space to render. I have rebooted 3 times and no other programs are running.I have adjusted the preview down to quarter, half and full. Resample is turned off. Nothing changes or help the lag time.
PLEASE HELP.
