I've put off doing this for a while now, but I just can't stand it anymore!

I recently bought an eMac, and the Ripple Effect in dashboard doesn't work! Someone I know has a 12" Powerbook, and it works there, so why shouldn't it work here?

The Apple system profiler says (under Graphics and displays):

ATI Radeon 9200:

Chipset Model: ATY,RV280
Type: Display
Bus: AGP
VRAM (Total): 32 MB
Vendor: ATI (0x1002)
Device ID: 0x5962
Revision ID: 0x0001
ROM Revision: 113-xxxxx-102
Displays:
eMac:
Display Type: CRT
Resolution: 1280 x 960 @ 72 Hz
Depth: 32-bit Color
Built-In: Yes
Core Image: Not Supported
Main Display: Yes
Mirror: Off
Online: Yes
Quartz Extreme: Supported
Display:
Online: No
Status: No display connected

I think it may have something to do with Core Image, which is not supported, bu shouldn't it be supported?

Does anyone have any idea why it won't work?

Yeah there are a lot of people upset... I know I was. It has to do with your graphics card and Core Image support.

"Other graphics effects and optimizations in Tiger, such as the ripple effect that shows when you place a widget on Dashboard, are driven by Core Image. When a programmable GPU is present, Core Image uses the graphics card for image processing operations, freeing the CPU for other tasks. To take advantage of Core Image, you need one of the following graphics cards:

ATI: ATI Mobility Radeon 9700, Radeon 9600 XT, 9800 XT, or X800 XT.
NVIDIA: GeForce FX Go 5200, GeForce FX 5200 Ultra, GeForce 6800 Ultra DDL, or GT DDL.
If you have a different card, contact the manufacturer for Core Image compatibility information."

I think I did see that article.

If it doesn't work on my eMac, why would it work on a 12" Powerbook?

because the powerbook 12" has a graphic card that supports Core Image, I think it has to do with pixel shaders. You're eMac's graphic card does not.

while the G4 cpu can emulate the effect, it would suck up your whole cpu do do the effect, and it would probably don't go very smooth, that's why it is disabled on computers not having a supported graphic card.

EDIT: And why apple can't use good graphic cards for a change, well.. it's another discussion Smile
