setting framerate to 50 with the frame massage on your patch make the display very fluid. 50fps correspond to 20ms between frame, and that's exactly the default output rate of line.

so everything is fine in your patch. once correctly configured it works perfectly. at least on my computer.

Hi list,

I'm using the patch below on Pd-extended 0.40.3 on a MacBook Pro, MacOsX10.4.11, to test the best setting for the [gemwin] initialization.

Even with a simple 4/3 [rectangle] I can't get smooth motions: if I increase/decrease its dimensions with a [line] (let's say increasing dimensions from 3 to 4 in 10000 milliseconds) the motion is not fluid, it changes by little visible steps. I've tried also to limit the amount of data from the [line] till 40 values per second without significative results.

Any suggestion? Thanks a lot! marco
