Ok, so I just bought subject to replace my GeForce FX5900XT in order to get QE and CI supported (of course the side effects of better gaming performance on the Windows side are a bonus as well).

According to the HCL it works fine but I would like to hear some personal experiences with this card - so do tell. Will I be able to get higher refres rates with this new card, or will that still run in only 60 Hz (I think my eyes are becoming accustomed to the low refresh rate by now - in the beginning it felt as though my eyeballs were bleeding but now they're fine; I hope anyway )?

Anyway tell me about OS X and X1600 Pro.

I had to add the deviceId in the kext but other than that it works swell. There are some artifacts that the mouse leaves sometimes, I don't know if there is a solution to that. I'm using 1280x1024@60 (but that's my monitors limit anyhow so I can't ask for more )
I've described the way I enabled QE and CI here: http://schrepfler.blogspot.com/2006/03/aft...all-it-was.html
I guess it's intended for linux users that dont quite understand what is what and where can they find it and not quite noobs but still very down to earth.

Hey thanks a lot. I will save a bookmark to your blog so when I get my card I'll follow your instructions. Great

Is your card AGP or PCI-E? If AGP, did you have to muck around with IOPCI2PCI or not?

You said your monitor's max res is 1280x1024, so maybe someone who has a higher res screen can comment on whether they can do 1680x1050 or not? I've been digging the forums and asking but haven't gotten a reply yet.

Have you tried OpenGL stuff? What do you get for framerate in UT2004, for instance?

Your instructions says I need to boot into single user mode. When I do that I get presented with the choice of two command procedures I can execute. One is for modifying files and the other is for booting the system while still in single user mode. I assume I can execute the second group of commands so I can boot up the GUI to edit the files, or?

It's a AGP card, haven't touched IOPCI2PCI.
I know the chess program now works and the flurry screensaver, I don't have UT2004 nor the space for it so I can't comment (windows works great for that).



I don't remember to tell you the truth. I can tell you right now that as I installed 10.4.5 a couple of days later I did all the procedures from a normal system (running as vesa) so in the end no single mode is necessary.
Just modify the kext and delete the driver cache files.

Plz say , in more detail (step by sptep) (i also like you , have video card x1600Pro )
How you make it all ...

schrepfler - I've got an X1300 (PCI-e), and I've tried your instructions by adding the ID in to the kext, and remove the cache and mkext... I've rebooted, and now I get a kernel panic when it tries to load the X1000 kext.

Any ideas or suggestions at all?

Perhaps the X1300 is not supported with the driver? I'd remove the deviceId and go back to vesa?
If the X1300 is based on the older generation processors perhaps you might try to add the deviceId to the older Ati driver?

I also have a x1300 and i would like to know if i can at least get full opengl acceleration

I really don't know about the X1300, hope someone will give a hint. As I didn't see it on the HCL I doubt it's supported. I guess, it's up to Apple to decide if they would like to build computers with the X1300, I personally wouldn't as I don't find it a powerfull enough card. Who knows, perhaps they'll decide to put one in one of the Mini's?
Being left to the mercy of one vendor is kind of rough.

I have an ATI Radeon 1600XT PCIe and I'm unable to change the resoultion in System Prefs. I changed it manually in com.apple.boot.plist to 1280x1024x32@75Hz....wouldn't boot. Seems I'm stuck at 60Hz as well, even though my monitor can go higher.

(I haven't bothered adding my device ID to the x1000 kext, but I still get CI/QE support)

how about instead
1280x1024x32@75Hz
1280x1024-32@75
?

I too have an AGP X1600 512 MB, and I was also wondering if you could post a step-by-step guide. Your tips help out but more detail would be most appreciated.

Have you tried Borisbadenov's method? My PCI-E X1600Pro with the same deviceid works perfectly - QE and CI enabled, no tearing, res. and refresh switching and vice versa.
