I tried this trick from a posting on Macintouch.com
MacInTouch Reader] The XBench scores are not directly comparable. The PPC binary portion of XBench 1.2 was compiled against 10.4, while the Intel binary portion of XBench 1.2 was compiled on 10.4. This means that the Intel code is running into the coalesced update limitations.
You can perform an "even" test between the PPC and Intel systems by disabling Coalesced Updates on the Intel iMac before running Xbench. Open "/Developer/Applications/Performance Tools/Quartz Debug.app", choose "Tools -> Show Beam Sync Tools" and choose "Disable Beam Synchronization". (You can do this on the PPC mac, but I don't expect it to make a difference).
My score went up from 60 to 88! Not sure what it does though.
Celeond D 2.68 O/C to 3.79.
Full Version: WOW - Xbench
Didn't do squat for me.
Mine went to 102 from 73 but does it matter?
I guess you pobably need QE to make a difference and it just show how useless Xbench is.
Did nothing for me too, my score was the same but I don't have QE so it must be just for those that have QE.
LOL. Now I have 202 score on User Interface Elements which scored bad all the times

Turning that option off actually disables QE and/or CI .

Coalesced Updates
Mac OS X 10.4 introduces a new behavior of coalescing updates that enables Quartz to more efficiently update the frame buffer during each display refresh. In addition to increasing system efficiency, Coalescing updates improved visual consistency and eliminates "tearing" during scrolling and animation. To coalesce updates, the Quartz window server composites all window buffers into a single offscreen frame buffer before flushing it to the screen. When your application issues a flush command, the system doesn't actually flush that content until the next available display refresh. This allows all updates for multiple applications to happen at the same time. Window server operations (window resize or move, for example) are handled in the same manner—coalesced into a system-wide screen update.

It's apparently broken and Apple hasn't fixed it (Maybe in 10.4.4). Anyways, you can make it permanent by setting the deferredUpdates value to 0 in the /Library/System/Preferences/com.apple.windowsweevwe.plist file. It's under Compositor.
Thanks scousi! Towards the bottom of the article can show you how to disable Coalesced Updates also.

Umm... what?
My Xbench went from 80.5 -> 104.63 by disabling Beam Sync. I got almost another point by enabling QE 2D:

Where is the /Developer/ folder?
QUOTE (skyliner34 @ Jan 25 2006, 06:44 PM)
Where is the /Developer/ folder?
You have to install the Xcode package on the DVD.
Ok thanks. Is Xcode included on the 10.4.3 8F1111 DVD?
Yes, it's the Xcode tools directory.
So, does anybody know how to set OS X to disable Beam Synchronization on boot?
I assume there is some plist (like that to enable Quartz Extreme 2d) that needs to be edited but I do not know (and I already looked in /Library/Preferences/com.apple.windowserver.plist).
Do we need a special thread for this tangent?
EDIT 3: Nevermind, I just found it:
This also works:
http://www.macosxhints.com/comment.php?mod...rder=&pid=58254
NOTE: After rebooting, relaunching Quartz Debug will re-enable Beam Sych. So to verify that Beam Sync. is actually disabled, open com.apple.windowserver.plist with /Developer/Application/Utitlies/Property List Editor.app and look for Root->Compositor->deferredUpdates to be set to 0.
One more thing, this Beam Sync. speed trick may only work on LCD displays.

On the install DVD durring install, it has a button that says "custom" or something like that at the bottom on the last step before you click install. But you can still do it from the dvd, i think, open on desktop, find the folder that says packages if not in there maybe in some exrtras folder or something, then just click it and it will start the install.com.apple.windowserver.plist

I'll have to try this trick I ran xbench two times the first was low like fifty something, the second time though it was 79 and the only thing that had changed was I had reinstalled it onto a maxtor 100 mb sata drive where before it was on a very old maxtor pata... that and itunes had expired so I had dropped it the trash can.
Open terminal and copy/past :
sudo defaults write /Library/Preferences/com.apple.windowserver Compositor -dict deferredUpdates 0
type your password and ok
repair permission, reboot
it's permanent.
