hi, i did a patch to draw a lot of line in a space (tableau2). The coordinates of the line, the angle, the diameter and the time are get in a jit.cellblock. i use the poly~ object with subpatch (map1b) who contain a jit.gl.sketch to draw a lot of line in a same time or different time. In max 5 the Fps is good for my use. But now i work with Max6, and the Fps is slower. why? would you know an issue to solve this problem? (i'm sorry, i know my patch is very tortuous ... ) Cordialy, thank's for your help
