iMac mid 2010 graphics issues after installing Yosemite
I notice that after my Mac comes back up from sleep, graphics seem to be a bit slow.
Opening up the Downloads from the dock where the files Fan up seem jerky. Most impacted are the 2 games I have.
Playing Sonic racing and Castle of Illusions Mickey Mouse play slow and jerky. Lot of dropped FPS. Overall graphics are slow.
After I restart my Mac, everything is fine again. Never had this issue with Mavericks.
I tried "Reduce Transparency" Didn't help.
I even did a fresh re-install of Yosemite from scratch (booting up in recover mode, wipe out everything and download and install).
I don't have much software installed either. MS Office, Chrome, Google drive, PS, Lightroom. That's it.
Still the same problem. Mac wakes up from sleep and graphics are poor. Games run very jerky with loss of FPS.
I'm guessing Yosemite has some issues with ATI Radeon HD 5750. This is frustrating...
iMac, OS X Yosemite (10.10)
