Mono being faster than .NET with SetPixel must have been on a particular case... I have found a huge performance issue with Mono and Get/SetPixel() in a particular situation, making Mono crawl... Something instantaneous with .NET can easily take 10 seconds with Mono (the perf hit is exponential, too). I couldn't make a reduced test case for that one either yet...
But hey, that aside, I've been happy with Mono too. :p Dan Shryock wrote: > > On Fri, Mar 20, 2009 at 8:40 AM, LKeene <[email protected]> wrote: >> >> I actually intend to use it to draw to a memory bitmap pixel-by-pixel, >> rather >> than calling SetPixel() each time.
