Hello All, I've noticed from reading through the PG Pro manual that _OtherNullEvent gets passed every tickcount or 1/60 of a second. It's setup in FN pGinitRuntime. If I understand the manual correctly 1/60 of a second is the smallest unit I can use for this. I have a function that needs to be called repeatedly a lot quicker than this. My question would be is there a way I can force PG Pro call my function quicker, say at least every 300 / 400 us or can anyone explain to me how I would go about calling my function at an Interrput Level if this would make it be called quicker then every 1/60 second. Thanks in advance, Sean.
