depex Posted September 6, 2009 Share Posted September 6, 2009 Trying to figure out how to fix some Photoshop CS4 redraw lag. It lags when I move around multiple layers, and more with more stuff. If hold down the arrow key to move something, the item will keep moving for a while after I release it. OpenGL support off, 11.0.1 update installed. Tried with both Leopard and Snow, also with both ATI and NVidia cards. Quartz enabled. Current motherboard is Maximus II Formula, cpu Intel c2d E8500, 8gig ram, Geforce 8600 gts, Two 24" lcd (hp lp24775w and benq g2412hd). Everything else seems to run just fine. Any help would be greatly appreciated. Edit: Tried rosetta, which was even slower. Also tried disconnecting one monitor.

depex Posted September 7, 2009 Author Share Posted September 7, 2009 Tried some more stuff. Not using system drive for scratch. Ram at 95% Cache at 8. Same in CS3. Here is a test file. http://xeped.com/test.psd 1,4mb If I move around the top layer group it lags horribly. Holding down ctrl+shift+arrowkey for 10sec will make it move for 15sec after I release it. And if I delete the stuff group, the lag is gone. So filesize doesn't matter, but the amount of layers does.

U.C. Posted September 7, 2009 Share Posted September 7, 2009 This happens with me too. I disabled OpenCL, that helped, but didnt fully make it go away. EDIT: I tried this and it seems to work great now http://www.anthonywyatt.com/blog/2009/02/0...-cs4-brush-lag/ Link to comment https://www.insanelymac.com/forum/topic/184629-photoshop-cs4-redraw-lag/#findComment-1256111 Share on other sites More sharing options...
depex Posted September 7, 2009 Author Share Posted September 7, 2009 I should also note that it worked perfectly in Win, so it "should" be possible to fix.
