justin0six Posted September 11, 2012 Share Posted September 11, 2012 I successfully installed Mountain Lion on my ASRock H55m Pro socket 1156. My CPU is an Intel i5-750. Anyways, my resolution is stuck at 1280x1024 and the graphics performance is very very sluggish. For example Launchpad is ugly and the bar at the top is white. So I'm assuming that the OpenCL isn't doing it's thing? Here's my Graphics info: Asus GeForce GTX 570: Chipset Model: Asus GeForce GTX 570 Type: GPU Bus: PCIe Slot: Slot-1 PCIe Lane Width: x16 VRAM (Total): 1280 MB Vendor: NVIDIA (0x10de) Device ID: 0x1086 Revision ID: 0x00a1 ROM Revision: 70.10.38.00.03 Displays: Display: Resolution: 1280 x 1024 Pixel Depth: 32-Bit Color (ARGB8888) Main Display: Yes Mirror: Off Online: Yes PCI info: Asus GeForce GTX 570: Name: NVDA,Display-B Type: Display Controller Driver Installed: Yes MSI: No Bus: PCI Slot: Slot-1 Vendor ID: 0x10de Device ID: 0x1086 Subsystem Vendor ID: 0x1043 Subsystem ID: 0x8387 ROM Revision: 70.10.38.00.03 Revision ID: 0x00a1 Link Width: x16 Link Speed: 2.5 GT/s I've tried all the different system profiles, even though I wouldn't think it would make a difference. I've completely ran out of options. Any help would be greatly appreciated. Thanks! Link to comment Share on other sites More sharing options...
