ani0712 Posted September 2, 2012 Share Posted September 2, 2012 I installed Mountain Lion using USB drive (method described in very same forum). Since I have Sandy Bridge CPU, I was struggling to enable its onboard HD 3000 graphics. But, out of curiosity, just now I installed Mountain Lion update 10.8.1 from Apple, my AMD Radeon HD 7670 (1GB) was detected as ATI Radeon 6840 and I booted without using GE=No. I also got full resolution (1600x900). Now how will know in my QE/CI is enabled? I am getting artifacts sometimes. Also, I had option of switching GPU from HD 3000 and AMD Radeon. So how to know wcich GPU is active right now? Because, though it detects my AMD card during booting, System info shows resolution 1600x900 below my HD3000.
