Workaround for the 27 inch iMac Flash lag?
We've had a few users tell us about performance lags that they're experiencing with their brand new 27" iMacs. Our own Casey Johnston even wrote a quick article about the problem last month. Now that everyone has had a few days to play with the issue and try the obligatory troubleshooting steps, we've been tipped about a possible solution. One of our readers claims that this isn't just related to Flash playback... it's possible that this lag problem is consistent across the system. Flash taxes your system more than most applications so it would show the lag problem more consistently than another application -- thus making it look like a problem only with Flash. The suggestion at this point: cycle your wireless connection. By turning AirPort off and on again, some people are seeing the computer regain responsiveness. Obviously this isn't a permanent fix because the issue will most likely appear again after you reboot your machine... we can't say if the fix will persist for the entire session, either; the problem could come back before reboot. Fellow TUAW blogger Joachim Bean suggests that the issues may be something related to PCI Express. Both the AirPort and graphics card are using PCI Express to communicate with the system. There's a possibility that the lines of communication are crossing during use. I'm still betting on a software issue -- at least, let's hope for that. Let us know if this helps, or any other possible solutions you might have in the comments. Thanks, Simon!
27-inch iMacs reported to have Flash playback issues
If you were contemplating buying one of those shiny new 27-inch iMacs, maybe don't pull the trigger just yet: according to Engadget, many proud new owners of the computer have become annoyed new owners, reporting pronounced problems in particular with Flash playback. The problem doesn't appear to be a few isolated cases, as two separate threads (here and here) have popped up in the Apple support forums, nor is it a pandemic, as Engadget reports their iMacs are fine. The suggested causes have ranged from a corrupted Snow Leopard build, to a bug that spins down the hard drive, to the nebulous "bad permissions." In the meantime, though, those big beautiful 27-inch screens are playing video like a 128K trying to run Crysis. A user on the first thread reported that Apple phone support said the problem was with the graphics card, and that it should be fixable in a software update, though another customer who opened a ticket was instructed to exchange the computer itself. Is Apple going to have to smack down another of its chip partners? We shall see.
