Brain! Before you hit the panic button do a wipe of the HD and clean install without the migration stuff (if you have a clean clone of your 10.3.9 on a boot-able drive you can always restore from that). Much talk on the web re various extensions and startup apps that have fatal results in Tiger. Good luck.

(Tiger is still sitting in the unopened box on my desk waiting for some of the dust to settle.)

I've been hearing quite a few having trouble with Tiger via the clean install option so you arent alone Brain. Might just have to install it a different way for now.

Nooooooo! The reg install worked for my g5. Also I think tiger adds mouse lag, I feel it, but right now I cant prove it. GL brain.

Most lag i've seen so far has been involving AppleWorks. Many times it will just suddenly freeze for a moment, beachball comes on, then it goes back to normal. Most of the times this happens when I try to save a document i'm working on. Could be it needs an update for Tiger but with Pages out, beats me if Apple will. I got Pages but I really do not care for it. Course I don't need to make newsletters or magazine ads. For that stuff it does seem pretty sweet. But I just want the simplicity of Appleworks when I do my typing. Guess its just what i'm used to the most.

his favorite game?

I successfully restored my 10.3.9 system from backup using Disk Utility's Restore function, after Dana's advice. It worked great. As for Tiger, well, stuff happens; I'll install it when I feel like it. My Powerbook, though, has no strange startup files so I'm installing Tiger today on it.

I had a problem with two different Maxtor FW drives in the OS 9 days, and replaced them with LaCie drives. I DID get hung on whatever that OS X upgrade was that had trouble with FW drives; it wiped a LaCie out before Apple posted the warning to update your FW drivers.

I had to follow up. Let me start over.

When I installed 10.4 tiger I experienced mouse lag in ut. Later I found out that tiger will synchronize redrawing the screen to the apps redrawing on the screen. All of the apps draw to the screen then it is refreshed. This is slower then if every app draws willy-nilly, and movment appears less responsive.

To disable this, and return back to fast responsiveness, I used quartz debug to disable the "tiger vsync". See my previous post for instructions.

Today on my favorite mouse forum(lol i know), it clicked.

The main disadvantage of VSync On is simply additional lag between mouse movement and visible feedback on the screen. For example, when you have a 100Hz monitor and, as it is common, frame reate drops slightly below say to 90fps, VSync on would make this drop to 50Hz (20ms interval)

Now, a mouse motion would be delayed by up to 20ms before being shown, and this additional mouse lag is something I, personally, tend to avoid. Of course its even more on LCD monitors which typically run at 60Hz, but I suspect nobody using a LCD does care about instant mouse reaction anyway 

And even high-end gear typically drops below 100fps when there is alot of action on the screen, and thats typically the moment when you are in dire need of reaction speed

So keep that quartzdebug open and configured when playing UT my clan buddies.

edit: and since im bored

That again is a question of the person watching. I simply cant stand the ghosting and bluriness of even the fastest LCD screens (4ms is currently top, I think). Interestingly, I read an article that even 0ms response time would be blurry, simply because the pixel stays lit and the eye, tracking the movement, sees the blurring. Thats the reason why they are currently developing LCD screens where the backlight is flashing after each refresh, but this is only possible with the fastest LCDs (you dont want the flashing to be below 100Hz for the same reason you dont want it with CRTs).
