Hi, I just purchased Photoshop CS6, running it on my MBP 2.5 GHz i7, 16gb ram. Waste of money... Photoshop CS6 is A LOT(!) less responsive than Photoshop CS4, particularly the curves dialogue. I just can't work "fluently" with CS6. Anyway.... moving forward, I was wondering if anyone here experienced similar slack performance of CS6 on Lion, and if an upgrade to Mountain Lion would help? (Every other software runs just fine, including all the other CS6 applications. It's just Photoshop CS6).
