Sorry to post this here, but I absolutely cannot find a solution to this problem on google. I want to start utilizing the Rotation tool in CS4, but it does not work because openGL is not enabled. When I try and go to preferences in photoshop and then performance, it wont let me toggle on the "enable openGL box. By the way, I'm using a 2.2GHz Macbook Pro Santa Rosa, not the new unibody ones. Is there anyway I can fix this? My friends older macbook pro can rotate canvas but mine cannot... so I have no idea what is wrong. I am also using a cintiq and I can rotate canvas just fine in painter but yeah... anyways I hope someone can help me. Thanks! 2009-04-16T00:15:01-04:00 6 2009-03-31T03:15:46-04:00 16263 false false 13639 2765 1 2009-11-08T07:15:30-05:00 782 I'm pretty sure it's the cintiq, why don't you send it to me and I'll fix it for you... 16263 Post 2009-03-31T03:19:25-04:00 421068 506 2009-03-31T03:19:25-04:00 <blockquote><cite>quakerninja said:</cite> I'm pretty sure it's the cintiq, why don't you send it to me and I'll fix it for you...</blockquote> Neewwwmmaannnnn If I send it to you, I'll get it back with dried ninja jizz all over it I kid I kid. But I don't think its the cintiq, I disconnected it and I still cannot rotate canvas.... 16263 Post 2009-03-31T03:37:42-04:00 421076 2765 2009-03-31T03:37:42-04:00 No clue. I have pretty much the same setup (mine's 2.4GHz, though) and it just works. 16263 Post 2009-03-31T08:53:01-04:00 421200 1661 2009-03-31T08:53:01-04:00 http://kb.adobe.com/selfservice/viewContent.do?externalId=kb404898 basically: Preferences/performance/click the opengl thingy. it works, woohoo! 16263 Post 2009-03-31T10:59:31-04:00 421264 3643 2009-03-31T10:59:31-04:00 Thanks guys, @eZ-kun I tried doing what you suggested, but it's greyed out and wont let me enable openGL at all. I can't even find a way to update my video drivers. So lame..... 16263 Post 2009-03-31T12:47:23-04:00 421313 2765 2009-03-31T12:47:23-04:00 Hey I'm new to this site, but I had the same problem and though I should add what I found. It seems the 128MB 8600m GT (at least in the MacBook Pro 2.2) is blacklisted, so you won't be able to enable OpenGL. However, you can download a plugin from Adobe that will let you enable it! Grab it here <a href="http://www.adobe.com/support/downloads/detail.jsp?ftpID=4051">http://www.adobe.com/support/downloads/detail.jsp?ftpID=4051</a> I dropped the AllowOldGPUS.plugin into: Applications > Adobe Photoshop CS4 > Plug-Ins > Extensions It works perfectly, but keep in mind that due to the lack of video memory, you can only have 6 OpenGL accelerated windows at any time, less if you also have an external monitor attached and have dual desktops. Windows over the limit will just be normal Photoshop windows. Looks like Adobe was just covering their asses, rather than there being a huge performance problem. Imagine all the customers screaming when they can only have 3 accelerated windows open at once. I hope this helps! 16263 Post 2009-04-16T00:15:01-04:00 442367 13639 2009-04-16T00:15:01-04:00
