I am working on a project, a wedding video to be specifi... I have noticed my system running very sluggishly. I pulled up task manager and vegas was using over 600MB ram... I saved my work.. and closed Vegas down. Reopened it and project showed about 64 MB being used... All I did was start playing a section on the timeline and for every second that played the memory usage was going up by about 3 MB.. this shouldn't be happening.. did I do something wrong? did some setting get changed? I figure if i want to play the whole hour and 20 minutes I would need a couple of terabytes of memory. please help!!
