Yeah this is correct, and i think explains everything.
So you saying this is a VRAM amount problem on that specific card?
That is a bug as listed by 666sheep. That is seriously the 4th time I have had to explain that. The amount of VRAM you have is meaningless. It's all about the GPU. There is absolutely no GPU Core Image support in a 9200 even if you could connect 8GB of VRAM.
His post:
This.
The same situation is with 9200 PCI. In 10.5 - Hardware Accelerated. Curious thing: PCI cards by default won't support QE (it can be enabled by hack).
So, with 9200 PCI 10.5 ASP says: Hardware Accelerated CI but no QE
It is a bug in how system profiler reports a 9200. Get it?
i know that , i just think it was a misinterpretation of what you wrote and what i wrote that lead to confusion . i always do jump when i explain or try to explain something and think everybody can follow what i thought but didn't wrote or said
and yes i know why it is called graphics processing unit and central processing unit and where the difference is , but it is core image that decides which processing unit is appropriate to handle core image , and CI's preferred processing unit is the GPU and only if the GPU cant do what CI wants CI is using the CPU if the CPU can handle it or if you or a App would specifically tell core image to use the CPU instead , unlikely but not impossible as you could read in one of the articles how to force CI to use only the CPU
so in "theory" you could make a totally unsupported computer like a iMac G3 under tiger try to make it display the ripple effect , ok the likely outcome would be that the iMac will freeze because its to much for its CPU
thats why these effects are automatically disabled by OSX on a Mac that does not support core image
a reason why nobody has managed to install successful Leopard on a iMac G3 to my knowledge , but it was successful on a iMac G3 with a G4 550mhz CPU upgrade

Well i just installed Leopard, ATI 9200 is reported as Software as i was suspecting, overall Leopard is running fine on that g4, once i get my 1gb stick it will perform even better

Good to hear things are as they should be. Was Leo at 10.5.8 yet when you last ran it? If not the info bug must have been fixed in one of the updates. The memory will help a lot as Leo doesn't even really come to life till you hit 1GB or more. The 128MB over 1GB you will have will help you run at least 1 extra app over people with just 1GB even.
At least you have Quartz Extreme support and I also believe the 9200 supports rotation right?
the 9200 should support rotation at least as i have a samsung monitor which can be rotated ,practical for documents as the 17" is the right size for Din A4
it was possible on my mini and on the eMac (1.25 model,with monitor connected as extended desktop) which both have the 9200
just 1 side note , if you can install screen spanning doctor
you can connect a monitor and spann your desktop across and make then use of both displays instead of mirror only
as apple had disabled that feature in the iMac G4/G5 , eMac's ,iBooks
and the kind doctor enables that feature again

can be installed under panther and tiger
but i am not sure if its possible to install on leopard , but it did work on leopard after upgrade from tiger on my eMac ,
so should work too,but i am back to tiger
but read the whole article

Since he is only has 32MB VRAM and is running 10.5 I would advise against that. 32MB is just enough to get by on one screen in my opinion. I know it can be done and will work but you would be slowing down all the 2D screen drawing and the whole system would seem slow.
He is already running Leo on sub-867 hardware so it seems like a bad idea to do even more to worsen the experience. In his situation he should be doing everything he can to increase performance.
only did want to point out all the options , and i find it a great feature ok never really tried to run leopard on a sub 867mhz Mac ..
i'm just a tiger and classic fan

Well yeah, QE and QuartzGL are supported, the 1GB Stick is on its way so i will for sure see an improvement, so far with 640 mb and sub 867mhz i can say at least under Leopard the browsing experience is far better, using safari 5 and not TenFourFox here, scrolling and page renderings are better, Tiger is faster for sure, but once i get my 1gb ram i will see if i should stick with Leo. I don't think rotation is supported at least i didn't see any report on that in System Profiler, also i completely disabled Spotlight Indexes, and Dashboard since i don't use any of those two.
Well since i don't multitask i'm ok with it, i've found that even at 800MHz it runs fine for web browsing, itunes, emails etc, as i said i will see what improvement will bring the extra GB ram i will put in it, but i think i will stay with Leo, it totally worth it. Thanks for all the tips
