merauder75 Posted August 30, 2011 Share Posted August 30, 2011 Hello, I followed a guide (http://www.insanelymac.com/forum/index.php...p;#entry1338125) getting my BFG Nvidia GTX 295 Dual-PCB to work, and it does, however, it completely lacks OpenGL acceleration (tested it with GLview, benchmarked horribly for 1.8GB of video RAM), and I cannot change resolutions without editing com.apple.Boot.plist. I also have a problem with severe flickering in the App Store and with the mouse cursor in general (something having to do with the frame buffer). I have looked at this (http://www.insanelymac.com/forum/index.php?showtopic=259485&st=20) page as well, and I think the instructions are close, but not quite what I need. I am not using any special kexts for the card, all the NV*.kext stuff is in /System/Library/Extensions, and it is enabled via EFI string in the apple Boot plist. My Boot plist: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>arch=i386</string> <key>GraphicsEnabler</key> <string>No</string> <key>Graphics Mode</key> <string>1280x1024x32@60</string> <key>Timeout</key> <string>2</string> <key>Legacy Logo</key> <string>Yes</string> <key>EthernetBuiltIn</key> <string>Yes</string> <key>device-properties</key> <string>(its a really long string of characters i removed for cleanliness's sake)</string> </dict> </plist> Also, as a semi-related question, would it be safe to force my architecture to 64 bit? I am pretty sure my Core 2 Duo E6600 is 64-bit. Please help!

merauder75 Posted September 1, 2011 Author Share Posted September 1, 2011 Umm, i downloaded EFI Studio, and my GTX 295 isn't listed anywhere EDIT: I see a driver for the single PCI version, will this work with the dual PCI version with the correct EFI string?

I am not sure about that. Why don't you clone your working version of hack into another partition & then risk it?
