What often helps is to change the slot of the audio card (best is far away from the graphic card) Hope this helps, Gilles Hi Martin In Logic with Asio-Driver: increasing to 8192 (186ms) in the control-panel of the hammerfall: not really better in SoundForge with MME-Driver set the buffer to 1024 kb (highest possible): little bit better, but if I have the highest zoomresolution and the wavescrolling is running fast the audio is only stuttering and slows down. If I deacrese the graphic-hardware acceleration the worse it becomes. So it has to do with the graphic-cards. Martin Saleteg schrieb: > What buffer size are you running on?
