Diablo® III

Frame rate plummets/ stuttering lag

My mac defaults to using high graphics across the board, and I generally get 60 or so fps, but as I play every few seconds my FPS plummets to 0 instantly. Even playing on low setting I have the same problem. It creates a stuttering affect that makes it nearly impossible to play. It seems to happen mostly during large effects areas, i.e. when I am walking around with no monsters there is no problem. I have had a similar problem lately with SC2 as well. It is not a heat problem as I have SMC fan control running and I am using a cooling pad. I have reset my PRAM and my system management controller, ran a disk utility and I have automatic graphics switching turned off. Not sure what else I can do. Please help, thanks.

Well, that troubleshooting guide didn't help at all. And these tipps aren't really helpfull at all. I mean "Restart your System" and "Close other Applications"....really? That are things one could come up by oneself. Nevertheless, thank you.

I (and two friends of mine with also MacBook Pro Notebooks) did everything BEFORE that troubleshooting guide and did it again after we read it. Didn't help.

I am running the game with everything off or low and 800x600 resolution. My FPS are 10! 10!
Mac User need a Patch.

These are factors that can contribute to low performance. Specially with Lion and some Macs where if your Mac sleeps/wake, performance will remain low until you restart your Mac.

If you are having issues, please post your information so we can review and send up for feedback.

If you are not having the same exact issue as the original poster, please create a new thread about your issue.

Obtaining System Information
    1. Hold the 'Option' Key and choose System Profiler/Information from the Apple Menu.

    2. Copy the information from the following sections:
  • Hardware (remove the Serial Number line)
  • Graphics/Displays
  • Software (remove the Computer Name and User Name lines)

Have you made sure that your 9600 graphics card is being used and not the 9400 chipset? The article for troubleshooting has a link to Apple's website to show you have to configure your 9600 to be used over your 9400.

Ha, that did it! I switched to "Higher Performance" and now i can play at my highes possible resolution and nearly all settings maxed out with 30 FPS. If everything is turned off (but highes resolution) its nearly 60 FPS.

BUT that can't be THE solution. Because on my Windows 7 VM the game runs at 40-60 FPS with all settings maxed out.

So, if someone else has the issue, you can use the "Higher Perfomance" Setting to avoid that issue, but Blizzard SHOULD solve this problem nevertheless!

This is different on Win than Mac. Win uses Direct X and has shader fully enabled for this chipset (4.0 I think) where Apple has this limited to 3.0 I believe and uses OpenGL.

Well, i understand that, but if a system (not mine!) fulfills the recommended systemsettings, then you could estimate that the game runs fluently, independent of the Energy-Saver-Settings :/

Though, i appreciate the support here, good job so far!

I have gone through and done every one of these troubleshooting options short of the AHT which doesn't seem to be pre-installed on this laptop and is not supported from a download. The only thing that seems to have changed anything was installing the updated driver package, after doing this and restarting my computer D3 ran smoothly for about 15-20 minutes before experiencing the same stuttering lag problems I faced previously. I am going to attempt to verify/repair my hard drive permissions again to see if that will help. Do I not have any other options at this point?

Hi everybody !

I don't understand why did it work fine with the beta (until one of the last patches) and why is the fps so ridiculous with the commercial game?
That's really not my job to fix it out. The game is choppy even with low settings (no shadows, etc...). Please find something, i don't want to have regrets about my purchase.

Regards.

Same problems on an quad core i7 iMac running Lion and 12gb of ram with a 2gb video card.

Game was running perfectly until act 2 when the windy sand effect came up. Now it's choppy even when I return to town.
No other apps running.

Just an update, when I plug my MBA on the battery charger the game runs with a decent FPS rate most of time, especially in closed environments as dungeons.

Since installing OS 10.9 Mavericks on my MacBook Pro Retina, I m having the same issues as the original poster. The game stutters so badly that I can no longer play hardcore. I have done all the usual diagnostics/repairs (rebuilt drives with Disk Warrior, reset PRAM, rebooted cable modem, etc.), and I am starting to suspect a problem with the game code and Mavericks...
