Poor results with Nvidia GTX 260 - Any help?

[glenlivet]

Hello!

I have managed to run 10.8.4 on my old PC.
I have a GA-EP45-DS3 motherboard and a GTX 260 graphics card.

Here is my org.chameleon.plist :

<key>Boot Graphics</key>
<string>Yes</string>
<key>Default Partition</key>
<string>hd(1,3)</string>
<key>EthernetBuiltIn</key>
<string>Yes</string>
<key>Graphics Mode</key>
<string>1680x1050x32</string>
<key>GraphicsEnabler</key>
<string>Yes</string>
<key>Kernel</key>
<string>mach_kernel</string>
<key>PciRoot</key>
<string>1</string>
<key>Rename Partition</key>
<string>hd(1,4) "Snow Leopard"</string>
<key>SystemId</key>
<string>5244B044-33B9-3FBB-95F9-6786D60C7E34</string>
<key>Theme</key>
<string>LoginToLion</string>
<key>Timeout</key>
<string>5</string>
<key>npci</key>
<string>0x2000</string>

​

Well, everything seems to be right except that the fonts are not OK (especially visible on the bold ones).
They aren't well defined and I feel it's not normal as I have other partitions with 10.6 and 10.7 which don't gave the same result.


I tried NVEnabler (which I use on 10.7) but with this I get a scrambled colour screen after boot sequence.

Can you give me some piece of advice? Any idea?
Thanx!

This doesn't appear to be how MultiBeast configures org.chameleon.boot.plist. I would copy that and save it somewhere and use MultiBeast to create a fresh one and see if that works.

Thanx for your answer.

I tried re-using Multibeast post install (both EasyBeast and DSDT-Free install).
At first, both gave me a blank screen after reboot.

I solved this by adding PciRoot=1 and my system was able to boot...
but I still have this poor font resolution.

I also did a benchmark with Unigine Heaven and the score was as low as this:

32 bits colors is OK and VRam too.
