I had patched a video mixer which run on a intel core duo laptop,(OS 10.5) creating about 15 frames / second.
Now using the same patch on my new i7 2.3 gHz Laptop (10.7) it gives around 20 frames /second, but the reaction of the mouse and key object goes up to 4 seconds the longer the patch runs. So absolutely no spontaneous video mixing is possible anymore. Envolved are : scissors and Glues / brcosa / up and downsizing of matrices and jit.op *
Thanx for hints how to get the patch reacting spontaneously again.
