@P0NT: lol, I'll settle for a patch.
@Spárkys: great, but since you said "only when you demage some randoms objects in game, walls etc.", try to lower the Physics? Maybe it is a bottleneck. (http://i.imgur.com/g9fOE.jpg to the right of Vertical Sync, under Shadow and above Clutter).
@keybox: if you had obvious screen tear then Vsync was definitely off. I tried to play with Vsync off when testing and the screen was cut in two halves/layers. If you go windowed (borderless), your Desktop Refresh Rate will become active. It can be different than your Fullscreen Refresh Rate. Since you have 60Hz/FPS in Windowed mode, try checking in the control panels if your Fullscreen Refresh Rate is set correctly?
@DarkLumen: check out this chart below and CTRL+F your "5750".
Then look at the left column for "GTX460" (it is one tier up).
Now, check out this benchmark:
You can see that the 5750 should get about 50~55 on 1080p all high, a bit less than the 460. So try the 16GB flashdisk or SSD solution? It could be you are dipping because of access times.

Yeah, that was before using Afterburner. No screen tearing now, but after further testing from my previous post I'm still get ridiculous dips in frame rate in certain areas, mostly on the beginning of Act III (outside). There doesn't seem to be anything in specific causing it in every case, earlier it was happening with absolutely nothing going on at all. No fighting or monsters about, nothing falling from the sky, no animated background. Odd.
And you're right about the refresh rate for Fullscreen. Framerate has capped at 30 again after switching back from Fullscreen Windowed. I can't figure out how I specifically change the refresh rate for Fullscreen apps. I'm on W7 and go to Screen Resolution, then Advanced Settings, and the only option available is 60Hz. Doesn't specify desktop or fullscreen.
Going through Device Manager just gives the same context window, but I could be doing something wrong here. If you have the time/patience to walk me through it I'd be pretty grateful.
You're doing a pretty good job at keeping this thread together and helping everyone out, as well. Blizzard should be thanking you, haha.
I'm afraid nothing works for me... :( However, thanks to the ppl who actually tried to help the community with the "slow motion" aka stuttering.
Blizzard please fix it guys.
Shall we buy a Nasa styled PC in order to play D3 or what? There's absolutely a big amount of ppl whose PC are incredible good and run many new games at full, but Diablo 3...
This is definately an engine issue imo...
That is something you can easily change settings for. I had the same problem on a laptop about 5 months ago and you have to go into the control panel for your graphic card and change so that the Nvidia card is the one rendering your game.
for nvidia, it seems to run better on the exact opposite setting, go figure. vsync forced in nvidia control panel, disabled in game, and run in window/window+full mode. otherwise fullscreen+vsync drops fps from 60 to 30 when it would normally go from 60 to 55-57 in a laggier area and then of course 30fps is like slow motion sluggishness >.<

I did it like that:
- turned off vsync in game
- turned on vsync and tripple buffering from nvidia control panel
- caped both in game max fps to 60 (my refresh rate is 60HZ)
- edited HardwareClass "1" in \Documents\Diablo III\D3Prefs
And now my game works as a charm.
I've noticed that running it in windowed mode will also fix shattering problem.
I'm using NVIDIA GeForce GTX 550 Ti and...
...the micro stuttering seems to be completely gone.
All that's left is slowdowns when too many objects are moving on the screen.

What people does not seem to know about V-Sync is that if u drop to anything under 60 fps lets say 59 fps, it will lock the game to 30fps untill your fps can increase to 60. This may also cause some slight input lag. I can explain V-sync and Tripple Buffering further if anyone is interested.
yeah i noticed that, and letting nvidia manage the vsync with window mode seems to do a lot better job than the in-game vsync. not sure about AMD users :/
Edit: does anyone know exactly what HardwareClass does? mine is set to "6" i'm thinking maybe it enables/disables some settings in the engine like reduces some shadow effects or something. someone else posted this: "Setting hardware class to 1 seems to remove the shadowed backgrounds around text/numbers as well. So combat text basically looks like junk."

@FatDice: hmm, do you mean the vsync part or the fps cap? It's unlikely that your performance will drop due to a cap, unless you set the cap very low.
@Aristar: alright. The downside to windowed mode is that AMD Crossfire is not used; the game will run on one card. I paid for CF, I wanna use it ;-)
@Motaro: it's good to hear that you have got performance, but I would like to mention something: D3 on my gaming pc has default hwclass "6" and on my old laptop from 2008 it has hwclass "1". Also see Aristar's comment about hwclass. This could explain the performance gain. AFAIK there is no official explanation of hwclass yet but it's probably safe to say that they are profiles (from low to high).
@Rinex: good comment and you are completely correct. I wanted to include this in the OP but I have to draw the line somewhere to stay on topic. So I settled with the text "you need to have atleast 60 fps".

Update for Radeon Crossfire users. Check out the CAP 2 that was released on may 25th. It has a Diablo profile that was not mentioned in the release notes. I've been playing with it for an hour and it seems to have fixed the micro stuttering and de-vsync for me.
Please post there if it work for you.
