Re: [PD] Pd GUI poor performance
Another solution could be to reduce the maximum number of messages sent to the gui per tick. IIRC this is a #define somewhere in the sources and you'd have to recompile pd, but I did this once on an advice of Miller and it worked very well (except for the slow gui framerate). Apart from that there is an external called speedlim (you could also build that as an abstraction using vanilla) which might be more elegant than using a global metro. -- Orm Am Donnerstag, den 06.

Re: [PD] Pd GUI poor performance
what is the global gui refresh metro ? and do other graphics cards have different options besides ShadowPrimary that allows fast access to pixel data? Can look it up but seeing that you have recently been dabbling in it...
