I meant that immediate blitter is not set, but instead "wait for blitter".

Did another test. I defined two copperlists, one very small and nothing special, the other with the wait/jump feature (which i posted here). When i switch from the normal copperlist to the other, the framerate immediately reduces. Can this copperlist really slow down my program?

Yes, the copper has priority over the blitter and CPU. The CPU can run unaffected as long as it only needs to access true fast ram, and the copper will only "steal" every other available access, but in general a larger copperlist will make your program slower. |
