LSP was running desperately slow for me and I thought perhaps this was the result of bugs - however I'm running it on a brand new AMD machine (Win 7 Home SP1, AMD A4-3400 Radeon HG Graphics 2.70ghz, 6GB memory) and thought this can't be right, bugs or not. After some reading around I found some settings to turn off which has helped a little bit. So I thought it might be worth posing the question, are there some settings to turn off/on or programs that might conflict or other tips that may help speed up transition or macro processing or stop a jerky preview, etc. Share your experience. Thanks!
