League of Legends performance worse on OS X

Well if your Macbook goes up to a 100 degrees then there's certainly something wrong. Mine doesn't go higher then 60 or so. Even while gaming.

Sadly, 100º seems common. My MBP hovers at 40º while idle, and my MBP has often gotten too hot and throttled itself playing D3.

so i have 2 cases only for League of legends

- on my iMac 21.5" 650M on macos i get 60 FPS and in large battles i get 32fps
- on my macbook air 13" hd 4000 under windows 7 i get 45 with 20 fps

The difference, as I'm sure you know, is the video card. The intel 4000 is pretty craptacular. Even the new drivers for it, which can increase your frame rate by up to 20%, only increase it by 20% of crap. Plus the air has a slower CPU, less memory that it has to share with the GPU...
 
cMBP 2.3 GHz, 8 GB RAM, 256 GB SSD, Geforce GT650M.

1440x900 All on High.

80 FPS constant through game even at team fights.

It would help if Apple updated their OpenGL support more aggressively... ML is still on what? 3.2?

3.2 is supported at 70% with my GT 650M. The latest version to be 100% supported is 2.1. Results are similar with integrated graphics.

NVIDIA's website says all GT400/500/600 series should support OpenGL 4, while OS X doesn't support it at all after what, 3 years? So there's that.

Hopefully that's something to look forward to in OS X 10.9. Even Intel graphics would benefit from it.

+1 i hope that too. You all know they are working on wifi and graphic drivers for 10.8.4
 
Someone who appears to have either a Hackintosh or a modified Mac Pro along with an AMD Radeon HD7970 gained support for an OpenGL 4.1 extension (ARB_separate_shader_objects) with 10.8.3, along with full 3.2 support, so there's hope.

Please stop spreading misinformation! Mountain Lion fully supports OpenGL 3.2!
OpenGL has two API profiles - the old compatibility profile and the newer 'core' profile which provides cleaned-up API. The 3.2 is supported as part of the core profile, as will be all the future GL versions. Apple also provides a list of GPU capabilities exposed under OpenGL API: https://developer.apple.com/graphicsimaging/opengl/capabilities/

And besides, the GL version number has fairly little to do with the performance, unless we are talking about certain demanding graphical techniques.

That extension is supported under every GPU which is capable of running ML, save for the HD3000

More like incomplete information than misinformation. All I said was correct, I simply didn't mention which profile I was talking about, but you could have figured that one out from my screenshot.

But thanks for pointing the profile thing out, I assumed the default profile OpenGL Extension Viewer used was the relevant one, as presumably did several people who I've read say ML only supports 70% of OpenGL 3.2. I didn't catch the second image I posted (not from me) had the Core profile selected.

If I choose the Core profile I do get the same result with 100% 3.2 support:

How on earth? I have the same Macbook Pro and get really unstable framerates.

Remove the option to wait for Vertical Sync. I have had problems with unstable FPS, specially at TF's. Removing it helped a lot.

Now it runs between 76-84 FPS.

Yeah I did that already, sadly still pretty bad framerates :(
