Hi all,
Anyone have a handle on the graphics updates in the latest OSX update yet? I’m interested to see if they’ve actually closed some of the gap in their OpenGL implementation, but the details are sketchy.
Cheers,

Just installed it but don’t have a reference project I can use to compare to 10.6.4. The readme claims this update includes bug / performance improvements, but I’m not sure if this effects Unity projects yet.
Especially we would need people with ATI gpus to test it as ATI drivers have had some horrible bugs on handling of many VBOs and drawcalls
I’m running an iMac with ATI,RadeonHD2600 graphics… what’s a good test to see if things have improved?
Not to be mean, but 5 year old GPUs don’t count I fear as they are weak out of the box and thus the lower performance is not nearly as impacting. The problem is more that the current gen (HD4k+) chips suffer bad FPS that are in the 5-10% range of what they technically should have if the drivers weren’t that borked.
But you can test it through a terrain with foliage likely as that ramps up the VBO and drawcall counts extremly far extremely fast (use pixel error 1 and drop in enough trees and detail objects and use the configuration bars of the terrain to scale up and down and see the impact)
I just tested before and after the update… I went from 50FPS to 75FPS.
@zinks - What kind of machine are you using? I’m on an old, x1600 graphics Macbook Pro. I can’t remember what sort of framerates I was getting before as I’m pretty much using Unity under Windows only now.
@bigkahuna - I was working on my work machine which is a:
MacPro 8 x ~2.66
~4 gigs of ram
Nvidia 8800 w/ 512 vram
In the scene I was playing with, I had terrain, trees, several models which exceed the 1500 - 3000 poly sweet spot, around 20 1024 textures and the following image effects applied:
Bloom and Flares
Depth of Field
God Rays
SSAO
I was testing at full screen, which I believe is roughly 1680 x 1050.
I don’t know if this is an OSX issue or Unity issue, but as of Unity 3.1 and OSX 10.6.5 my copy of the “ocean shader project” no longer works.

This ranks all the scores from highest to lowest based on CPU or grfx card or OS etc. by clicking on the column. It is based on Cinebench benchmarking which is from Maxon.

It essentially is a 3d scene that pegs all the levers to the max and spits out scores after stressing all of the components to construct, calculate and render the scene.
