HELLFISH Posted June 8, 2012 Share Posted June 8, 2012 Hello. I have recently installed the Gigabyte 6850 video card. I am using <key>AtiConfig</key> <string>Duckweed</string> <key>AtiPorts</key> <string>4</string> <key>GraphicsEnabler</key> <string>Yes</string> This works very well, and I get a NovaBench Graphics score of 442. But, after the system sleeps, I have a problem. The graphics turns very poor performance. After sleep, the NovaBench gets a Graphics score of only 114. All other benchmarks (RAM, CPU, Hardware) stays the same. Only the gfx is affected. A reboot fixes the problem, but again, after sleep, the very poor gfx performance is again present. I am running 10.7.4. Is this a known issue? I'd like to use sleep, but I don't want such poor gfx performance. I am using Gigabyte EG45M-UD2H with Q9550 processor. Only non-vanilla kexts are ALC885_889a.kext, realtekRTL81xx.kext, and of course FakeSMC.kext. DSDT was generated using the old MaLd0n auto-patcher.

knizmi Posted June 8, 2012 Share Posted June 8, 2012 Are you using a MacPro 3,1 smbios? Try a different one, iMac 12 or MacMini 5 for instance. Just don't use MacPro 4 and 5 or your system will KP during boot, unless you delete the AppleTyMCEDriver.Kext. 1 Link to comment Share on other sites More sharing options...
