Photoshop CS6 – Lion vs MountainLion

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).

Thanks for your reply. Good to know it's ok on ML, but I'm still not entirely convinced if it's my specific machine/setup or the OS... unless someone had slack Cs6 performance on Lion which then changed for the better in ML.

Not keen to upgrade to ML yet – certainly not if I know 100% guaranteed that CS6 will work smoothly.

Just a quick update:
I upgraded to Mountain Lion, and Photoshop CS6 is running alright now.
Previously (under Lion), there was literally seconds(!) of delay within the curves dialogue, as well as some filters. Same for the clone stamp live preview: always 1-2 seconds behind the actual mouse pointer position.

Anyway. All good now.
