[SOLVED] CINEBENCH : Errors in rendering are displayed as red pixels ?

[mac_carol]

Hi mate

 

 

I'm running the osx ML-10.8.3 (12D78) with my PowerColor ATI HD4650 1GB ( 1002_9498_22691787.rom )

 

 

I've injected the HW-IDs (0x94981002) into 2 kexts: ATI4600Controller & ATIRadeonX2000

 

and I've also remap the video path based on bcc9's guide

I modified the Gliff framebuffer with my custom personalities (CRT-DVI-HDMI)

 

 

The QE/CI works almost perfectly

 

 

 

 

 

 

 

 

 

I can play a movie with both Mac's DVD Player & VLC Player

 

 

NOTE: As you know, Apple effectively prevents the user from taking screen captures of visual DVD content

I can also play 3D/OpenGL game, such as Neverball

 

 

 

 

 

 

 

 

Everything is almost perfect,

 

the only issue I get is when I try to perform an OpenGL test using the CINEBENCH

 

 

It keeps reporting this error

 

 

 

 

and the test will look like this:

 

 

 

 

 

 

 

Maybe anyone here know how to fix the issue ?

 

Any help will be greatly appreciated

 

 

Thanks & Regards

Hi, Carol!

 

Gilles (gils83) was also having this issue: perhaps he has already found a solution?

 

All the best!

[mac_carol]

Thank you theconnactic

 

I've already read his reply,

but he said that he get no red-pixel issue only in Lion 10.7.3

 

 

I've also serched google for any solution

 

and I found that the same issue might also occur in windows too

it said that the red-pixels issue can be fixed by disabling the CATALYST A.I.

 

So the questions are:

 

1. how can I disable the CATALYST A.I. in Mac ?

2. are there any apps like CATALYST CENTER in Mac ?

 

 

[theconnactic]

Well, i never heard of it.

 

Few drivers have standalone apps or even preference panes of their own in OSX, unlike in Windows, where there seems to be a standalone manager app for almost every single driver, making this kind of tweaking surprisingly more intuitive.

 

To be honest, i don't even know if the Catalyst exists under OSX, since Apple itself provide all drivers for AMD cards: http://en.wikipedia.org/wiki/Radeon#Macintosh

 

All the best!

I have solved the issue by rolling back my Chameleon to v2.1-r2069

hello ,

 

je n'ai que le problème en x86_64 sur Lion et ML , les problèmes disparaissent en i386 , bizarre que tu es le bug en i386 , je pensais que c'était lié seulement qu'au mode x86_64 , ça réouvre le débat

 

I only have the problem on x86_64 and ML Lion, the problems disappear i386, weird that you're the bug i386, I thought it was related only mode only x86_64, it reopens the debate

sorry, but I think you're missing my point here

 

my i386 bugs is not related with the red-pixel issue

since I hadn't been able to boot my osx with arch=i386 until I found out that the latest version of chameleon was the cause why i got the KP due to AppleEFIRuntime.kext when booting the osx with arch=i386

 

now with the Chameleon-2.1, the red pixels issue has completely gone under osx Lion with either arch=i386 and arch=x86_64
