UT in Classic may require it to be upgraded to version 436. I'm pretty sure the OS X version requires 436. http://www.macgamefiles.com/detail.php?item=10164 You'll have to update via Classic. edit: D'oh! I missed the bit about it failing during install.

I've been running the game on my dual 1.2 GHz G4 with a Radeon 9800 Pro and even with the graphics turned down, some of the Desert Combat maps crawl in the single digit range. But that's a 3rd party MOD. Most of the normal maps I've played seem fine. 500 is pushing it. I personally wouldn't...

The video chipsets in those 12" powerbooks suck. The FX 5200 Go is not a very powerful chipset. Halo uses very advanced features to provide the higher quality texture effects. The official OpenGL standard for Pixel Shaders are Fragment Programs. They're only supported in hardware Radeon...

Do you have the graphics settings cranked up? I recall there being an issue where if I played with the graphics settings cranked up, there'd be a particular object that I'd look at that would crash the game. However, that was back when I was using a standard Radeon. Once I upgraded to a...

Those developers who were(are?) working on the opensource drivers are trying to use the Linux drivers as a starting point. If I had time I'd try and help them but time is one thing I cannot spare. :(

Gah!! I had a really long post but the forum didn't post it... I'll have to shorten this one. I had a SBL in my Mac until I bought a Radeon 9800 Pro. Since the R9800 doesn't accelerate OS 9 graphics and the SBL is an OS 9 only card, it went into a drawer. Creative support sucked. They had...

There's no audio card that would help with performance in Macs, so that's not a total loss. You can always get a USB or Firewire audio device to get 5.1 sound. But the lack of video card and Altivec is a bummer.

Yeah, CoreAudio makes heavy use of Altivec if it's available. Add to that the high priority thread CoreAudio gets and you get a pretty darn fast software audio system. If anything, game porters should rework their audio porting libraries to use CoreAudio rather than the Carbon SoundManager...

When it comes to audio, OS X will spin it off into a separate thread, so dual proc machines will get a slight benefit from audio being processed on the other CPU. This is why dual proc machines don't suffer from the same UT2K4 sound bug which single proc machines suffer.

The UT2K4 demo contains a bug that causes the sound code it eat up a ton more CPU power than it needs to. Turning off sound will provide a big performance boost and give you a glimpse as to what performance could be. Normally, the sound should only be taking up 3-7% of the CPU time, but due to...

No, that's not correct. There is no audio hardware acceleration in OS X. CoreAudio handles all of the sound processing using software. Hardware is used strictly as a means to output sound, not process it. The recently released OpenAL codebase that Apple released is just a thin layer of code...

Many games work just fine with 6xFSAA on my Radeon 9800 Pro in my Mac.

ATI released a new ATI Control Panel with 3D Overrides for all retail Radeons. http://www.ati.com/support/drivers/mac/macos10-2-ATI-displays.html These aren't new drivers, just the Displays utility. If you're not familiar with the 3D Overrides, they're options that allow you to enable and...

UT2K3 doesn't take nearly as big of a hit when sound is on as the UT2K4 demo takes (~5% to 40%). So it would seem there's some issue with the sound code in UT2K4 that affects performance more than before. It doesn't seem to be the OpenAL lib used in it so it might be the actual game sound...

Someone in another forum mentioned that it fixes the zoom bug when using NV Shaders, a GF3 or GF4Ti, and OS 10.3.2. BTW, since I've seen so many people ask the same questions over and over again in various forums, I put together a quick Halo performance info page. It's not close to done, but...

There's no commercially available Radeon 9600 for Macs. However, with a little bit of tape, you can get the 9600s working in AGP equipped G4s. AYM mentioned it near the end of December. I've been using a Radeon 9800 in my dual 1.2 GHz Quicksilver since around the time they were first...

On Macs, always play with Light Flares on Low or Medium. When set to High or Extreme, the game will lag heavily, particularly in areas where there's a lot of lights. Right now, apparently the Light Flares are done in software because Apple doesn't have the necessary extension(s) available in...

Doom 3 may use parts of DirectX like maybe device input, but I believe the renderer is completely OpenGL based. It's not necessarily easy to port Direct3D to OpenGL, but over the years, the porting companies have been developing their own libraries to aid in the process. But there are still...

Don't click on the Outwar link. All it serves is to boost that guy's character's power up. If you see an outwar link, don't click.

The engine doesn't support anything about 1024x768. I've tried everything I can think of to get it working but have not been lucky. Manually editing the config file does weird things and ends up with an inaccurate cursor (you don't target what you mouse over).
