Image 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


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.

    So Macs are crap, what else is new? Reply

    It's always about what you're looking for in a computer. If you're building or buying a gaming rig, Windows is obviously the way to go for now. You make yourself look like just as much of a tool as the idiots using terms like "windoze" and "M$" when you make comments like that. The hardware is exactly the same and I find the OS fits how I use it better. I get commercial apps and a proper Unix shell in the same OS. Windows does the GUI thing fine, but sucks like a toothless hooker when you need a shell. Powershell is fine for those familiar with the .NET environment, but to someone used to Unix or even the half-ass CLI DOS/cmd.exe provided it's foreign.

    I'm sitting at a Windows 7 machine with my Macbook Pro linked in by Synergy off to one side displaying a bunch of terminals SSHed in to various Linux boxes on it second monitor, so I think I can honestly claim to not be biased in any direction among the big three OSes.

    Macs are not crap. The OS is crap, and dated.

    Valve can do all they want to the Source engine but it will never run as well as on Windows.
    OSX has many dated components. For instance it uses OpenGL 2.1 (or does 10.6.3 have 3.0 finally?)... the latest is 4.0. Which has been available on Windows for some time.
    OpenGL 2.1 is about equal to DirectX 9, at best. You wont get the Windows performance for this alone, and you wont get the graphical eye candy either and things like Tessellation.

    I'm surprised Anand does not mention this, but he does seem bias towards Apple.
    Either way, the issue of performance is atleast as much to do with OSX/apple itself as it is to do with the Source engine on OSX.

    Mac's definitely use openGL 3.0 (they have to to have openCL which is at the core of a lot of snow leopard's improvements). Reply

    you know, I've lived with mac for at least 4 years now, and I think I can say yes, mac is very crappy. Music eats up space like a mutha bitch so gaming is virtually impossible unless you prefer playing an unintended 8-bit version of half life 2. It's no surprise to me that mac is the worst computer rated on the chart, but this is also on the internet. anything goes so it's really hard to say I can trust these results. So mac will always be crap if you want to just do gaming. It's definitely a leader for those who love itunes and facebook, but if you're not totally about the whole social networking trend get a PC, because not only are they better at games they also accomplish giving the user knowledge about their new shiny device. My knowledge of computers is at the equivalent of a cave man hitting a brick against the wall and getting killed by shrapnel. This is simply because mac does everything for you and is already very easy to "personalize" because of it's ability of hiding every known fact about itself so that when it comes time to fix it you don't know jack squat.

    Zombie, are you retarded?

    Must be trollin'. OSX has so many logs that if you'd bothered to do a couple minutes of research you'd be able to find out exactly what problems you're having. Compare this to the annoying Event Viewer used in windows...

    mac tip

    open terminal,
    type cat /var/log/system.log > ~/FILENAME.txt
    in your home directory will be a nifty txt file full of all kinds of useful information.

    If all you need a MAC for is shells, why not just get Ubuntu or some other version of Linux?

    If the hardware's the same, as you say, then why pay a premium for Apple?

    Granted, Apple, like any linux-based OS, has many nice features that cater to its customer focus, but your reasons don't support your argument. And as far as this article is concerned Windows still exceeds OSX. I would like Win7 to regain some of the WinXP gaming performance, though. Just like I wanted XP to regain some Win98 performance.

    Ahh spoken like a true windows advocate. Mac OSX is not Linux based Reply
