Unigine heaven 3.0 support osx 10.7+
Finally something to put pressure on cayman in 10.8
Wanted to compare quality of nvidia/ati drivers in osx, here is results:
Test setup – 10.6.7 OSX, nvidia drivers – latest nvidia drivers for mac from nvidia site (256.01.00f03), C2Q @ 3GHz, 8GB ram
Used cs:source from steam, custom demo.
Settings – 1680×1050, all settings maxed + 4xMSAA + vsync off
Results:
GTX285 – 134.32 fps (something wrong with drivers in some moments of demo, really it has much better fps)
8800gt 1gb – 167.39 fps
4850 – 184.58 fps
GTX480 – 217.12 fps
5870 2gb – 228.75 fps
This is two opengl extension viewer screen from user with gtx260 and snow leo.
P.S. there is no dirvers for it for leopard, and it cant be backported from snowleo
using 10.5.7 beta ati drivers (jsut five kexts) and new natit, i got my 4850 working in 10.5.6 Leopard
You need to have OSX 10.5.6 or higher
What’s working – qe/ci, resolution change
What Problems:
currently only second dvi port works for me, and only with dvi-vga adapter
also, Display is recognized as standart vga/svga display, so only 4:3 resolutions available
only usefull for VGA connections – with switchresx(before using it, make sure u can change resolution) help i added 1680×1050 mode jsut fine
EDIT3(for4850): booted with dvi2vga(converter only, no monitor attached to it) in second port, and dvi connected to first port(closest to mobo), and voila,
display on first port properly recognized.
some vertical little screen jerkness sometimes
Pkg with drivers you will find in #radeonhd room on irc.osx86.hu
and now some screenshots
User with 4870 reported he has almost no problems with 4870, he just cant change resolution, results in black screen
Btw, 10.5.7 kernel also supports Nehalem i7 fully now.
P.S. I hope no other company than Apple/AMD will pretend they wrote drivers for 4850/4870 or nehalem i7
Some anonymous source suplied me with core i7 benchmarks on MacOSX
CPU is i7 920 with ddr3-1066 memory, cpux misidentified freq and multiplier for it, actualy it’s 2.66ghz and mutliplier is 20

now the benchmarks itself, they are very impressive, looks like ddr3 tri-channel memory helps it a lot.
geekbench1:

quad core penryn at 3.2ghz getting 421.5 points in same test, with ddr2-800 memory.
geekbench1 rosetta

quad core penryn at 3.2 ghz getting 307.5 points in same test, with ddr2-800 memory.
xbench(no hdd test included):

same test with 3.2ghz c2q

P.S. voodoo 10.5.5 kernel was used
