MacOS X OpenGL driver status
MacOS X 10.8 Mountain Lion was released earlier today and with it the hope for updated OpenGL. Currently the OpenGL Capability Table isn’t updated for 10.8 (or even 10.7.4) yet but there haven’t been much improvements anyway:
- Current OpenGL support is still 3.2.
- GL_ARB_instanced_arrays, GL_ARB_occlusion_query2 and GL_ARB_timer_query are still the only supported extensions from OpenGL 3.3 (all of which are supported since the first 10.7 release or even longer).
So how about bugfixes? Below is the list of bugs known to me and for which I have code to test them. For each GPU vendor I write down if the bug was confirmed (NV/AMD/Intel), is unconfirmed/not tested yet (?) or is gone/was never present (-).
The first bug in the list might have been fixed as the Intel I used to test it with is a HD 4000 and Macs with that chip came out after 10.7.4 so I assume they had more recent drivers than the other 10.7.4 installs. If anyone has a Mac with 10.8 you can test the bugs with the examples I linked in my last article and send me the results for the other GPUs and I will update the list.
| Bug | 10.7.4 | 10.8.0 / 10.8.1 |
|---|---|---|
| Wrong values from uniform structs (#10518401) | NV / AMD / – | ? / ? / – |
| Wrong names for uniforms in uniform blocks (#11335828) | NV / AMD / Intel | ? / ? / Intel |
| Rendering to an FBO without fragment data location 0 is not possible (#11826727) | NV / AMD / Intel | ? / ? / Intel |
| Uniform block layout qualifier ‘packed’ results in GLSL compile errors (#11884110) | NV / AMD / Intel | ? / ? / Intel |
| Default layouts of Uniform Blocks can’t be changed at global scope (#11884641) | NV / AMD / Intel | ? / ? / Intel |
So, not much improvements yet and still no OpenGL 4 on MacOS X Mountain Lion…
Update: 10.8.1 seems to have the same driver versions as 10.8.0
