I have reluctantly upgraded to 6.5 from 5.5.3 because the facility I'm at currently decided to make the move and it was becoming too much of a hassle to hand my 5.5 projects off to assistants who were working on 6.0.3 systems. There are plenty of things I like about 6, and most of the things I dislike I'm sure I will get accustomed to over time. But one thing is just KILLING me and that's the response time on the trim mode. I am a trim junky. I am constantly trimming cuts 1, 2, 3, 20 frames in the blink of an eye and looping the playback instantly. It's how I refine my cuts. It's by far the most important function of MC for my workflow and I rely on it being FAST and RESPONSIVE to my shortcut keys to keep my flow going as I edit. In 6 there is such a lag when I hit the frame trim buttons. I'm used to being able to tap in 3 or 4 frames and have the trim happen almost instantaneously. Now there's a good quarter to half second lag as MC moves the edit each...individual...frame. Even when i bring my playback quality all the way down to full yellow it still lags enough to be a huge nuisance.
I updated to 6.5 hoping this would be a big enough upgrade to fix the problem (and the overall speed of the system) but no dice. Has anyone come up with any way to address this?
