Diablo 3 - Performance Problem with MacBook Retina

I had the exact same problem. Poor Diablo 3 performace after 10.8.2 on both the LCD and an extrernal Cinema Display. Resetting the SMC worked perfectly.

I experienced the same issue. Only a SMC reset can resolve the issue. Can Apple please provide an update as mentioned by the author of the thread, the number of customers this is impacting. Please note users are often part of the vocal minority so this issue needs to be addressed before it becomes a focal point of miscontent.

I had the same issue (Retina MPB, updated to 10.8.2) and Diablo3 and SC2 framerate plummeted. Rebooting didn't help. Resetting SMC fixed it.

Update: the SMC fix is not permament. Something about switching external monitors on thunderbolt seems to bring the problem back, and doing the SMC is so far the only solution. Rebooting does not fix the problem, nor unplugging the external display.

Hi, I just want to mention that I have the exact same problem, and it is very unconveniant. Basically every time I want to play a game, I need to reset the SMC. I have a 15" rMBP, the base model (8GB RAM, 256GB SSD, 2.3 Ghz processor)

A few points to mention:

* This has started to happen only since OSX 10.8.2

* It approximately divides the performance of the GT650M (of rMBP) by 3 or 4

* It happens on every game, wether on OSX or Windows via Bootcamp

* Resetting the SMC fixes the problem until you either put you mac to sleep or reboot (I'm not sure if both or only one of the 2)

I hope the Apple teams are aware of this issue. Please fix it in the next update. The fact that the problem happens with every game assures that the issue doesn't come from Blizzard (as some users thought it was on some Diablo 3 forums).

Thanks

same problem here.....does anyone know some permanant solution to this problem?

Smc reset can solve it for some time..but it comes out over and over later on...

Thanks!

Alright guys, today Apple has released an update. In the description it said something about fixing graphic issues. I have updated, and launched Diablo 3 without resetting SMC. I need to mention that I had not resetted SMC for a few days so it should have been laggy in Diablo as it always is.

Well, after the update, Diablo worked fine, at normal framerates !!! I think the update fixed our issue ! Can you guys confirm ? Thanks

OH...really? Sounds good....

Where is that update btw? Thanks!

The update will show up under "updates" in the Mac App Store. I did it this morning

u sure that was an update apple released today?

I only saw a relavent update at Nov 8th...

Not sure that it has been released "today", but as of yesterday there was nothing. I have updated and had to reboot my rMBP. It was a small update and did not change the Mountain Lion release number (I am still under 10.8.2). However I am sure it has changed something, since i put my Mac to sleep again at lunch break and I just started Diablo 3 now and it's working well. Actually maybe better than before because I get 28 to 29 FPS on 2880 x 1800 with everything on high except shadows on medium, and I usually got 22 FPS with these exact same settings before.

When I did'nt reset the SMC, I used to get 5 to 7 FPS with these settings...

What was the update called? My App Store says "No updates available"...

I think the best solution for this problem is to downgrade from 10.8 to 10.7...

But you will need to clean install some special version of 10.7.4...

My macbook pro retina now works perfectly with Lion.

I'm also having D3 problems with the rMBP where it goes down to 0 FPS, and takes about a minute to come back. I have the base model, 2.3GHz 8GB 256SSD. I was trying to find this update you are talking about, but as the other guy said it says "no updates available." I guess resetting the SMC is the only solution, other than reverting back to Lion...
