Photoshop CS5 insane slow on Windows 7 x64 Ultimate

Question

I've bought a powerful machine, Intel I7 720Q with 8 GB RAM and 7200 RPM HDD and Radeon 5870 with 1GB VRAM, and after installing the new Adobe Master collection CS5 I found out, that both Photoshop versions x86 and x64 are very slow (I have a legal copy!)

E.g. when I open a 3MB file and I'm trying to move it with the hand, or scroll, it is going very slowly, laggy, 10x slower than on my 4 years old machine with CS2 !

Do I have to enable any kind of acceleration or something?

Thanks

Answer 1

Wow, seems CS5 is slow for a lot of people!!

I've found this KB from Adobe regarding OpenGL and GPU acceleration:

GPU and OpenGL support | Photoshop CS4, CS5

I'm pretty sure it could help you because you do have a powerful computer and this shouldn't cause CS5 to act like this.

Then, read this, for some other tweaks:

Optimize Photoshop performance | CS4, CS5 | Windows 7, Vista, XP

If you don't have a professional graphics card try this:

Preferences > Performance > GPU > OpenGL advanced settings > basic mode

Answer 2

I disable "enable openGL drawin" and restarted PS and... WOW - now everything works soo fast :)

Answer 3

I've just read that many people have problems like me. Especially with scrolling.. This is a patch for it.. Didn't try it yet though

Answer 4

I think you have some problem or misconfiguration with the hardware aceleration. I use CS5 in a Acer Aspire netbook with 4Gb ram, Intel Core Duo t5800 (very average) and a Intel Mobile 4 VideoCard, and it works reasonably well.

In Preferences-> Performance, I´ll try first with the Memory Usage option and the scratch disk, it's better to use a disk where the Photoshop is not installed, if you have 2 or more.

And of course enabling the OpenGL aceleration.

Answer 5

I had the same problem, everything slow on a decent laptop. Instead of disabling "openGL drawin" I set it basic under advanced settings, and voila. (64bit)
