None of the ATI drivers seem to work. The GPU in the iMac seems to confuse everything!

Things should be sorted with Leopard in October.

How pray tell will leopard sort this out?

Also the card in the iMac is a mobility radeon and ATi don't support these directly in their graphics drivers. They leave support up to the laptop manufacturer. However there is a program which will modify standard drivers to work on mobile chips. Now if only i could remember the name. You can find it on driver heaven though.

damn ok thankyou for that info man.

i tried halo. not a very intense game i know. but at 1900x1200 AA on and vsync off i was getting constant 50-70FPS. it was running quite well.

more to come.
 
static lines anyone? 24" iMac 2.8ghz

if i try to play HL2 in bootcamp on windows xp, i got lots of white static lines in the dark area's
and in other games as well, so the when i try the omega drivers it works lots and lots better, expect some shadows in HL2
but unreal 2 doest work at all..

anyone has the same issue?
 
Bootcamp is only beta at the moment. Leopard will ship with the final version with up to date drivers sir.

Boot camp on Tiger is more up to date than leopard at the moment. Plus anyone will be able to use a bootcamp cd made from leopard for bootcamp on a tiger machine.

So... leopard itself won't fix this problem, just the drivers which will work no matter what version of OSX you have installed.
 
But all Bootcamp is IS merely bunch of drivers.

It's an ongoing process to iron out the bugs, hence it's been an unsupported beta product. The fact that it will be a final, supported version on the Leopard DVD must mean it'll be a step on from the beta version with up to date drivers.

Once Leopard's out, the free version will be taken off the web.
 
DoFoT9 - I can't oc by atitool as well...
Did you try to run 3dmark? I have freeze at 3dmark 05 / 06 loading screen...
 
That would be software piracy though :eek:

Depends on the license. Also you have to remember that apple will have to release updates to the version of bootcamp in leopard. You will probably be able to download this and extract the drivers even in tiger. They are just stored in a DMG.
 
I know this thread is really long and pretty old now.

But I just wanna throw in my 2 cents.

I'm and avid gamer the stock Bootcamp driver for the new iMac is NOT optimized for the HD2600, of course I have XP installed on my iMac. I also have had ATI Catalyst 7.9 Driver for the desktop HD 2600 Pro installed, since day 2 (under windows)

When that configuration I have gotten the following frame rates in games under XP Pro SP2 (all recent updates)

Half-Life 2: Lost Coast (1920x1200, full HDR, max settings) 74.8fps avg
Counter Strike: Source (1920x1200, full HDR, max settings) 97.3fps avg
Doom 3 with FPS cap removed (1920x1200, ULTRA HIGH settings, 2x AA) 116fps avg, 88fps min
Unreal Tournament 2004 v3369 (1920x1200, max settings) 71fps avg
Americas Army v2.8.2 (1920x1200, max settings) 66fps avg
Enemy Territory: Quake Wars (1440x900 max settings) 38-45fps

I recently installed the Catalyst 8.0 Beta driver and spiced things up a bit by trying the desktop HD 2600 XT driver.

In CS Source I now get 99.8fps with same settings
An amazing leap to 55-61fps in ET Quake Wars, same settings as well.
and about 35fps with spikes to the high 40's average in Bioschock demo at 1440x900 max settings, which I didn't test with the 7.9 drivers so I don't have anything to compare to. I didn't get FPS numbers but Company of Heroes runs amazing, with everything maxed out at 1920x1200.

Stock clocks on this card are 600Mhz Core and 685Mhz Memory if nobody has posted that yet. Also you can not overclock this card that I know of, I've tried every solution I used on my gaming PC with a X1800. ATI Tool won't work, either will ATI Tray Tool. And of course there is no OC settings in Catalyst Control Center.
 
I thought the drivers were in 1 pack, how do you choose the XT driver over the Pro ?


I installed it all manually. Go to the Device manager in my computer properties, and upgrade the driver to the video card, skip all the automatic driver stuff and say you "have disk"


Also adding another game I didn't included in my list in my last post. GTR2 runs at an average of 85fps, at 1920x1200, very high settings.

With proper ATI drivers, this thing is a monster. Inaccurate benchmarks have given the new iMac a bad name. Also the driver performance is just not there under OSX, AOE3 runs like crap in OSX (sorry for the language) compared to the PC version. Quake 4 runs VERY bad in OSX also compared to PC.

Hopefully Leopard will make the OSX graphics performance shine a little more.

Also if anyone has figured out how to run 3DMark05 or 06 please let me know, I can not figure out why it locks up upon launch.

I'm very impressed with the results you are getting, I was wanting to get a mac when leopard came out to replace my PC but i'm a casual gamer with the odd high end game like bio shock and company of heroes, they wouldn't need to run at full rez, as long as they look and play decent.

Bioschock is playable, but does still suffer from some heavy slow down at times when the action starts to get crazy. but the slow down at the settings I tested at is around the low to mid 20 fps range, when I first tested Bioshock on the Bootcamp drivers, the slow down made the game unplayable (down to as low as 11-13fps slide show action). The amount of stuff going on in Bioshock is just crazy, probably not for a 8800GTS with a Quad Core, but I'd say any system the same specs or a little better than the iMac 2.8 will have trouble.

I'm really looking forward to Unreal Tournament 3, Bioschock uses the Unreal 3 engine, so I hope UT3 is a little more optimized and gets a little better FPS. But I won't keep my hopes up.

As far as going back to the original topic, I'm still stumped with the whole argument of what this video card really is.

My current system is a AMD 4800 X2, Geforce 7950 GT and bioshock works well but does suffer slowdowns at certain points and the same can be said for company of heroes. I'm redecorating and finding space for massive PC isnt easy, an iMac would fit in so much better and I have been wanting to try OSX for years now.
