[HELP NEEDED] Photoshop running slow


Youth Team
After using PS for 30-60 mins, it suddenly gets slower and slower. It lags big time, even if I just try to use the marquee tool or crop tool.

If I close it down and restart it, it works smooth again... until it starts to lag again after 30-60 min.

I am working on files less than 50 MB.

I have another 15+ year old computer with windows 32-bit running PS CC14 without any lags at all.

I've been searching the web and found possible solutions that did NOT work.

The PC:
OS: Windows 7 Pro 64bit (Running on a SSD disk).
GPU: Radeon R9 8GB

So far I have tried the following:

  • Tried PS CC 14, 15, and 17 .. They all give the same problem.
  • Changed scratch disks to 3 other disks (NOT the same as PS is running from).
  • Switched between ALL the GPU options under "Performance" in PS, and even tried to disable it.
  • Adjusted memory usage up or down. It doesn't matter.
  • Updated GPU drivers and OS.
  • Turned off Rulers.
  • Used the "Purge" to clear cache.

Funny thing is that I can use other Video editing software (not Adobe) where I edit movies at 5-7 GB, and there is NO lagging. Then if I try to edit 4-5 still images in Photoshop, it lags :-p hehe.. this is confusing me.

My Photoshop crashes after using for 2-3 hours straight.

Maybe the Undo History it keeps, somehow screws it up? Just an assumption.
