My AMD Sempron 3000 system works just fine (10.4.5 - latest security update). Sound works, lan works, usb works and my Connect3D ATi Radeon 9550 is detected and (i think) accelerated after a slight modification of the *9700.kext. I (as I guess all ATi users) have the wellknown mousetearing but a free license from Boinx made it bareable. Now to my question.

 

I know I dont have a highend system but from the database of Xbench I tend to think that my Xbench score is unusually low? Could someone with a comparable system specs (see below) make a benchmark and post the results so I have a viable value to compare with.

 

CPU: AMD Sempron 3000 (shows as 4 Ghz in about this mac for some reason)

Chipset: VIA K8M800, VIA SATA (Working with 10.4.3 kext)

Graphics: AGP X8 Connect3D ATi Radeon 9550 256Mb (memory correctly detected but listed as PCI card)

Install the developer tools, run Quartz Debug (in Developer/Applications/Performance Tools/), go to the Tools menu and select Beam Syncing or Hit Command-B, turn it off. Rerun and look at User Interface and Quartz tests.

 

Keep the App running, it resets it every time you close it btw...

Thanks!

 

Did it and gained double perfomance in userinterface tests and improved quartz test. Still I'm only at 33.3something all in all. Is this what should be expected from my hardware or are there any other obviouse bottlenecks?

 

Also is there a way to permanently disable the beamsyncing?

These are my results from the other night, my specs are;

 

2.8 Prescott @ 3.05GHz

1gb Dual Channel ddr ram

ati 9800SE 128mb card

7200rpm 80GB ATA drive

 

I also wouldnt put too much value into the results from xBench, how's the system feel? Does anything feel slow, like graphics or copying files or using itunes?

 

Looking at your post again, it looks like you biggest problem is the memeory speed. Which should not slow down your using the system for everyday stuff... Remember the PowerPC chips has seriously slow memory buses too.

 

And no, there's no way I know of turning it off. Since I rarely shut down my system now its not much a problem for me, but perhaps someone else has a suggestiong to disable the beam sync thing without having to open the app and all that.

my xbench scores around 40-45, in 10.4.3, 10.4.4 and 10.4.5. However, my machine feels nice and fast (faster than windows running on the same machine). I wouldn't worry about it too much. Like Bug said, as long as your system isn't dragging, as long as it feels fast, then don't put too much faith in statistics.

Thanks for all replies.

 

My problem is that the system does feel a bit lagged. It's certainly slower graphicswise compared to Windows XP. It turned a bit better after I turned the beamsync off and also (maybe a placebo effect) after enabling Quartz 2D Extreme. Still it's sort of laggy. When I compare my results with yours I see the biggest differance in the userinterface and quartz tests, leading me to belive its a problem with my graphics adapter. Alltho I see you also have a Radeon (a 9800 compared to my 9550).

 

Are there any other tests I can perfom to find out if I have activated the ati-driver as far as it can be without the atiframebuffer thing everyone is talking about?

Check in the System Profiler, look under Graphics to see if QE CI are enabled. That'll tell you right there if your card is actually accelerating anything. Since it's a 9550 you might have to edit the ATI9700 kext file, there are threads on how to do it. Its not hard at all, I'm editing the kext's and plist files daily to try to get rid of the mouse tearing. Just some advice: BACK UP THE FILES when you edit anything. That way you can start in single user mode (-s on startup params) and change them back if you get a black screen or a kernel panic.

I edited the appropriate kext and got both CI and QE working so I assume I did it right. I guess I'll have to wait for the openati projects framebuffer to really experiance full acceleration, but so do we all with ATi adapters I guess.

 

Is the startup log saved anywhere? I try to read the info there but I get to the GUI so fast that I miss alot each time. I tried finding it in /var/logs but to no avail. I think I see something about displayfamily in the messages but just after that I boot into GUI. Maybe that can give me some sort of clue.
