Apple Seeds Lion 10.7.3 Beta to Developers

Can anyone with an OpenGL 4.0 capable GPU (AMD 5000 + 6000 series) post their results from OpenGL Extensions Viewer on 10.7.3?

Go to the OpenGL tab and select the "Core" instead of "Compatibility" profile under the title bar.

There seem to be new cursors in 10.7.3 :) Only just noticed them. Look pretty nice :p

Reminds me of the BeOS cursor.

Lion is NOT perfect, and as I also said in the other threads, I can't shake the hunch that the loss of Bertrand Serlet played a part in how Lion operates.

Is that you that has mentioned that name several times and your theory that problems in Lion are due to his leaving Apple?

It sure looks like he left in March 2011 and I would have guessed that initial Lion development and testing would have been substantially complete at that time.

How does the timing of his departure fit into your hunches?

Yup, it was me.

RAM management is totally different or flawed in Lion. Unused free memory should not switch to inactive, not 2.5GB of it in one fell swoop.

Also, the animations are sloppy. Why, on the same system, does entering and exiting Time Machine look smooth every time on Snow Leopard but can stutter on Lion. The problems arise once the machine has been on and used for an hour or so. Also, when you come back from sleep mode, scrolling in Safari is juddery and video playback on QuickTime and VLC looks a little choppy. Reboot, and it's fine.

anyone else notice .3 is a little laggy? my air doesnt seem as speedy after it, and let me tell you chrome sure is taking longer to load everything. even after clearing all browsing data and all that. finder also takes longer to open and everything seems to genrally be a little slower.

The OpenGL version is at 3.2 and it won't change until, at the very earliest, the next version of Mac OS X is released.

The extent that 3.2 was supported changed multiple times with 10.6.x updates in Snow Leopard, with resulting speed ups in some games.

In the final build of Snow Leopard (10.6.8), the OpenGL stack is essentially the same as Lion's primary OGL stack. Apple's OGL implementation consists of OpenGL 2.1 and the vast majority of the APIs from 3.0, but will only allow the shading language from OpenGL 2.1 (GLSL 1.2) to be used. This is the OpenGL stack that all Lion apps currently use. However, in Lion, there is another OGL stack installed in parallel that also contains support for GLSL 1.3. Developers can technically employ this newer version, but it is about 4-5 times slower in overall rendering speed (according to OpenGL Extensions Viewer benchmarks) and would make their application Lion-only.
 
Have they fixed the constant crasches of finder/spotlight?

Mdworker and so on.. segmentation fault..

I now see why Lion was so cheap.

OpenGL 3.2 was never 'feature complete', it was OpenGL 2.1 and some OpenGL 3.2 extensions - GLSL 1.3 was never available until Mac OS X Lion since it required Apple to go back to the drawing board to build the OpenGL stack from the ground up that takes into account OpenGL 3.2 changes and the change in direct that OpenGL has been taking over the past several years.

I wouldn't take the OpenGL Extensions Viewer benchmark with much confidence given that there are a whole host of considerations that need to be taken into account when one writes a benchmark application in the first place. There are new extensions included with OpenGL 3.2 that need to be taken advantage of to boost performance - I think over all though I'd sooner have more consistency between different Mac's with different GPU's than having 'bat out of hell' performance but find there is iffy reliability.
