Hello everybody,

Your forum already helped with as much as every problem i had except one:

I am currently running Tiger 10.4.10 on my P4 2.66 GHZ with 1 GB of Ram and an NVidia Geforce 6600 GT (AGP).

My problem is that the OS X tells me that Quartz Extreme as well as Core Image are supported:



Nevertheless the UI feels somehow slow - and XBench is giving me the following results for Graphics:



I tried nearly every possible injector (NVinject, Natit, Titan ...) but nothing helped - currently i am using natit 0.2.

I even tried enabling Quartz2DExtreme and Disabling BeamSync which didn't change anything - so maybe my OS X is not even trying to use my Graphics Card to render the UI ?!

I am totally lost and would appreciate every help (even if you just tell me that my Graphics Card can't run OS X that would help).

Nice Greetings,

P.S. i attached my whole XBench Output - maybe that can help ...

Hi. I have been trying to solve a similar problem.
Everytime i start the computer i have to put the screen to sleep (i use my down right corner for that) so i can have full aceleration.
Try to make the same and say if this helps ...

Hmm ... no unfortunately this didn't help

Performance still gets no boost after putting the monitor to sleep.

Xbench isn't a overly good choice for graphics as it doesn't push the video enough to take it out of it's power saving mode. Try OpenGL Viewer, Openmark and or Cinebench. This may also vary by video card and motherboard as some boards will force x16 to x1 in a power saving state, in addition to reducing the clocks. The simple tests may not stress the card enough to trigger the high performance modes correctly or quickly enough to show the expected results.

I had the same sleep/perf issue with my 8800m GTS, but have come to the conclusion that it was more software flakiness than a real issue (just MHO) . IOW's, Using something like Openmark and Cinebench, I was always getting consistent/competitive numbers. Using Xbench and OpenGL Viewer I was getting low or inconsistent numbers.

With OpenGL Viewer... If you don't click the benchmark button and run the tests, the numbers shoot up into the low thousands, but sometimes, esp. after resuming from sleep, the numbers with the benchmark button enabled will also hit the same high numbers. Which is right/wrong, I' not sure, but it seems like an OpenGL viewer issue more than a driver issue. XBench as mentioned should just be ignored for video esp. if using a more current mobile graphics processor. Same thing more or less happens in XBench with the cpu if you use SpeedStep. The tests doesn't push the proc into a higher state right away, so the results are lower than expected.

Hi again,

Ok ist just tried out OpenGLViewer - one time without Benchmark:



and one time with Benchmark:



But i don't really know if these numbers are good or bad - but i think for a PCI-speed port (as AGP is not supported on my Intel-board) it's ok?

I even tried to enable Quartz2DExtreme again - but i don't feel any difference in the UI speed (nor do the Quartz Benchmarks of Xbench change - still an overallrating in the low 3x-ies).

I am just wondering if my system is actually using the card - and due to the PCI-Port-Speed it has to be that slow - or if the whole Quartz Rendering is done by my processor (which is an old SSE2 Only P4 and thus is very slow ...) - which would explain the bad UI speed.

Thanks again for all answers,
