Mac OS X Steam Performance: Half Life 2 Episode 2, Still Slower than Windows
by Anand Lal Shimpi on June 4, 2010 2:04 PM ESTImage Quality: Still Foggy
As Ryan pointed out in his more timely piece, image quality under OS X is noticeably worse than under Windows.
The Mac screen shots are foggier for some reason and despite the fix that was applied to Portal, Half Life 2 Episode 2 appears to have worse texture filtering quality under OS X than Windows. This is more pronounced of a difference than what we saw under Portal.
Half Life 2 Episode 2 - Windows 7 - Click to Enlarge
Half Life 2 Episode 2 - OS X - Click to Enlarge
It looks like something is wrong with the AF setting, reverting to Trilinear filtering confirms my suspicion:
Half Life 2 Episode 2 - OS X - Trilinear Filtering - Click to Enlarge
But AF isn’t completely disabled. Using the Windows version for comparison it looks like Half Life 2 Episode 2 just forces 4X AF regardless of what you set the texture filtering option to:
Windows 7 4X AF
OS X 16X AF
The sky and muted colors are still a problem and I can’t seem to find out the cause of that one. There’s some texture banding off in the distance in the sky that’s only visible in the OS X version.

I was just summarizing the result of the test. Macs are slower, yet more expensive. What's not crap about that?heffeque - Friday, June 4, 2010 - link
Basically you're saying that a Mac is slower than itself. That just plain stupid.GeorgeH - Friday, June 4, 2010 - link
Macs aren't slower. OS X is slower because you're comparing a game engine that's spent the last decade being designed and optimized for Windows with a game engine recently ported to OS X. You'd find exactly the same initial performance deficit if Valve ported Source to Linux.Saying "Macs are crap" based on the fact that their default OS is slower when running a specific program that hasn't been fully optimized for that OS is so asinine it's mind blowing.

Mac is what it is, not just the hardware with the Apple logo but also the OS, the 3rd party support and the niche it's carved for itself. If I have you pay more for less performance and a smaller choice of software then yes, I'll say Macs are crap.ibuckyi - Friday, June 4, 2010 - link
You have no idea what you are talking about. OpenGL has been the forefront of gaming way before DirectX came in to play. Stop making excuses for Mac and admit the loss. I'm sorry that your 2000 dollar machine can't handle 20 years of gaming. And to think by now Macs would be able to handle what windows has been doing for 20 years. Give up on the excuses, and just admit.. Steve Jobs got you!LaughingTarget - Friday, June 4, 2010 - link
Uh, OpenGL hasn't been at the forefront of gaming for some time. Once DX9 hit the market, it was pretty much lights out for OGL. Even the last major holdout, id Software, has backed out of OGL development and moved onto DirectX. Moving Steam onto the Mac platform is unlikely going to rekindle any kind of OGL interest since it lacks significant market share to put out any kind of real effort onto the platform short of just hastily porting major titles over.Strunf - Saturday, June 5, 2010 - link
And yet there have been Doom after Doom using it, and with evrery new one everyone is amazing by its graphical quality!!I don't think Id Tech would bet on a dead horse...

You are wrong. Rage and the new Doom (both id Tech 5 based) render things in Direct3D mode only on Xbox 360. The Windows, Mac OS and PS3 versions render shit in OpenGL mode. Well, PS3 actually uses PSGL, which is Sony's implementation of OpenGL / ES. Anyway, stop making shit up so you can support your silly arguments.sprockkets - Saturday, June 5, 2010 - link
yes, and the drivers made for windows vs. mac and the respective subsystems used have nothing to do with it either.ArizonaSteve - Saturday, June 5, 2010 - link
I wouldn't say Macs are crap, but I would equate Apple to Bose and Monster Cable.
