Steam Prompts OS X Graphics Update

Stoobalou writes "Mac gamers got a massive boost when online gaming hub Steam started supporting the platform a few months ago. The arrival of the online service, which allowed Mac-toting gamers to play some of the same games as their PC brethren, in some cases cross-platform, created a great deal of debate between the two camps, with the PC crowd pillorying Mac fans for the relatively poor performance of their expensive hardware. Now it seems that Apple has gotten the message, as they have provided a graphics update for OS X Snow Leopard which will make progress toward closing the gap between the two platforms."

      Besides the obvious evidence of people with MAC's dual booting and running the same games on both OSX and Windows on the same hardware and getting significantly better frame rates on Windows...

      The simple fact of the matter is that OpenGL is not the same interface paradigm as modern DirectX. In the early days of Direct3D they were quite similar, but eventually Direct3D evolved to have two different rendering paradigms.. one called Immediate Mode (like OpenGL) and one called Retained Mode.

      Now, Immediate Mode is a lower level interface to the hardware than Retained Mode is, and that in fact Retained Mode is implemented as a layer on top of Immediate Mode. OpenGL does immediate mode better than Direct3D's immediate mode, but as it turns out that doesnt actually matter in trms of modern game rendering pipelines.

      What Microsoft has done with this Retained Mode is encompassed many optimizations, and its all centered around queuing up many rendering calls that make up a scene frame. It can then issues large batches of rendering commands to the video hardware all it once, grouping similarly textured/shadered polygons together, as well as geometry that uses the same transformation matrix, etc.. so that the state of the GPU (shaders, texture sets, transformation matrices, etc..) needs to be updated less often than a visit-each-object-once Immediate Mode algorithm would have had to do.

      These state changes are expensive, often requiring the GPU to completely finish all other operations (flushing its own queue) before the state can be updated, greatly reducing parallelism. That visit-each-object-once algorithm in Immediate Mode could require 30,000 state changes while in retained mode that same visit-each-object-once algorithm only requires 5,000. As it turns out, this is a significant win that more than offsets the less efficient Immediate Mode.

      This could be implemented on top of OpenGL too, so OSX could certainly do it.. but the fact is that it hasnt been done all that well yet anywhere but DirectX and a few big-name ($$$) OpenGL-centric game engines that handle it themselves.

    That you take StarCraft 2 or Portal and run them on OS-X, then reboot that same system in to Windows 7 and the games run better.

    "thats' really an indication of your skill, not the platform"

    I'd have to side with @jythie on this one.

    I came from a video post production house heavy with Mac workstations and now work at a major network channel that's very Windosey. My god - I truly can't understand the world's sad devotion to Windows. I hardly ever heard from the 60 Mac users at my last job and now I spend most of my day keeping a few dozen HP 360 and 380 shitboxes connected, booted and trying to finish the work you ask them to do. There's always something falling apart on these systems and they're slow as ass.

    There's also a Mac graphics department with 12 machines. I MIGHT spend an hour a MONTH maintaining ALL of them put together.

    My two year old 8-core Mac Pro at home can run rings around the 12-core HP 380 G6 server at work. On top of that, the people here THINK THAT'S HOW COMPUTERS ARE SUPPOSED TO WORK and keep buying them. Cripes.

    On top of that, I'm sure I only spent half the money on all the Mac servers and workstations as they spent on this stuff.

    There's something to this OS X thing. I wouldn't write it off so fast.
