Tucker28 Posted December 27, 2009 Share Posted December 27, 2009 I installed Snow Leopard with the guide on Lifehacker here. The system is working, though I do get slow-downs here and there that are mildly annoying. The worst problem I have is with my video card, specifically when running 3D games (World of Warcraft primarily). The system will give me extreme lag sometimes depending on how much is on the screen and then eventually will lock up and not even Force Quit works. When this happens, I have to reboot the computer. I have been looking to see if I can find any information on SL with the 8800GTS 320, but have not been able to. The other day, I noticed that my System Properties shows the video card with 512MB of VRAM instead of the actual 320. It seems that I have the wrong kext loaded, but nothing I have tried has worked. I have used the EFI string, injectors, etc, but nothing ever works. I have searched this site up and down and I am quite honestly lost at this point. I am also concerned that if the VRAM is set wrong if it's possible that any hardware damage could take place. Here is the screenshot of the properties window: Following is my com.apple.Boot.plist file: <?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></string> <key>device-properties</key> <string>7a02000001000000010000006e0200000d00000002010c00d041030a010000000101060000010 101060000007fff04001e00000072006f006d002d007200650076006900730069006f006e00000035 0000004e7669646961204765466f726365203838303020475453205b4738305d204f70656e474c204 56e67696e65205b4546495d22000000400030002c006400650076006900630065005f007400790070 00650000000b000000646973706c6179100000004e005600430041005000000018000000040000000 00003000c00000000000007000000000e0000006e0061006d00650000000b000000646973706c6179 14000000400030002c006e0061006d0065000000120000004e5644412c446973706c61792d4110000 0006d006f00640065006c000000210000004e7669646961204765466f726365203838303020475453 205b4738305d0e0000004e00560050004d00000020000000010000000000000000000000000000000 0000000000000000000000014000000400031002c006e0061006d0065000000120000004e5644412c 446973706c61792d4220000000400031002c0063006f006d00700061007400690062006c006500000 00e0000004e5644412c4e564d6163220000005600520041004d002c0074006f00740061006c007300 69007a0065000000080000000000001420000000400030002c0063006f006d0070006100740069006 2006c00650000000e0000004e5644412c4e564d616322000000400031002c00640065007600690063 0065005f00740079007000650000000b000000646973706c61791c000000640065007600690063006 5005f00740079007000650000000f0000004e5644412c506172656e74</string> </dict> </plist> Could having it set to 64-bit affect this in any way? I didn't have any of these problems when I was running Leopard.

Tucker28 Posted December 31, 2009 Author Share Posted December 31, 2009 Sorry to bump this, but wanted to check to see if anyone has any advice for me. I've been searching for solutions to this for weeks and cannot find any. At this point am I better off going back to 10.6.1?

turkleton Posted December 31, 2009 Share Posted December 31, 2009 I'm having the exact same problem. I have the 8800GTS 320 as well and am seeing the same graphics problems. It should be noted that I do not have problems in Leopard (10.5). In Leopard I'm using the NVDarwin kext which works well. In Snow Leopard 64-bit (10.6.2) I started out using whatever was generated in DSDT which is when I too saw the 512MB discrepancy in profiler. After that I generated some EFI strings both from 32 and 64 bit Snow Leopard and from Leopard. Each one was different but all reported the correct 320 MB of memory. However, I could not tell that any of the strings worked better than any other. I also somehow got NVDarwin working in Snow Leopard but didnt see any better performance. From my testing, I'm seeing almost 10 fps difference between 10.5 and 10.6 in games like WoW. Also, Finder and Expose seem laggy and slow in Snow Leopard while nice and quick in Leopard. I have debated on going back to Leopard but I really like some of the new features in Snow Leopard. Long story short, im in the same boat as you. I hope someone can come along and offer a suggestion that works!

Tucker28 Posted January 1, 2010 Author Share Posted January 1, 2010 At least I know I'm not the only one with this problem. Hopefully someone will have an answer for us soon. Thanks for posting!

MikeysWorld Posted March 5, 2010 Share Posted March 5, 2010 At least I know I'm not the only one with this problem. Hopefully someone will have an answer for us soon. Thanks for posting! I saw somewhere that you may need NVEnabler.Kext & NVEnabler64.kext for an 880 GTS. Not certain if this will help with a 320 or the 512 model.
