Your post doesn't give much information, so we have nothing to work with. Would you like to give us your machine specs? Monitor size and depth? What FPS you are seeing? What are your settings for Marine Aquarium in the FPS area?

We're happy to help, but we need something to work with. :^)

Not quite sure what happened here.

I am running OS X 10.2.5 with 1.5GB of RAM and NVidia GeForce 4 Titanium on a Graphite G4. Also, a Sonnet Tech 1.2 GHZ processor upgrade. The fish are very jumppy, I don't know what to do, they weren't like that before!

I have a 17 inch monitor set to millions of colors and a resolution of 1056x792
96 hz refresh rate

msanta,

Please give your fps. Use the "show fps" check box in the settings window. The fps will show up on the lower left corner of the aquarium. Then please leave feedback at the order n dev web site so we can converse directly.

Thanks,
Jim O'Connor

Jerky movement
 

I also have VERY jerky/jumpy fish motion on one of my computers, the other one is fine. The jerky box is a 600 mhz iBook with 16 mb Vram, 684 mb RAM. I always run this on AC power. I've tried economizing video memory, which doesn't help. I've tried limiting the fps, which also makes no difference. I'm running thousands of colors. My fps (with nothing else running) is around 90. It's gotten especially bad recently, and I'm wondering if it's due to the latest OS update (10.2.6).

This is bad enough that I no longer use the product on my iBook. Any fixes in the works?

Economize VRAM helps when you get < 10 fps.

Powerbooks (until recently) had less than stellar video systems, and iBooks trailed them. Since we are getting 90 fps we are rendering 3 times the number required to get smooth animation so the problem isn't pure processing or graphics power, but we aren't getting the processor in evenly distributed time. I'm talking with Apple and I'll see what we can find out. I have a debug build which will tell you the longest wait between draws, which helps to quantify the amount of jumpiness we get in CPU allocation. Would you be interested in trying it?

Jim, thanks for your response! I would be interested in trying it, what do I need to do?

Dana

See the thread on "How To Contact the Mac Developers" which I'm about to start.

Thanks, will do.

For those who would like to help me quantify the jumpiness, ftp.orderndev.com with anonymous ftp, get MA2Debug.sit. The extended fps information is:

fps: xx.xx how many frames are rendered each second (the slider)
ms: xx.xx how many milliseconds between each frame on average
(xx.xx, xx.xx) max and min milliseconds between frames for the last second
Idle xx.xx how many milliseconds moving the fish (our code)
Draw xx.xx how many milliseconds spent drawing the fish (Apple code)
(xxx x xxx) size of the display in pixels

Set the fps slider to either end and the middle and record the values from the fps display in the lower left of the tank. Also, need basic system description.

Thanks.
