I have recently started using Premiere pro and I find when I am rendering a project if I try to do anything else like surf the web when I go back to Premiere either the program has stalled and I need to wait for an age for it to start again or needs to close completely. Do any wise members know how to optimisse a pc for Premiere. I have 2 gig ram, nvidia geforce 8500 gt graphic card and am running vista ultimate
