Thanks for putting together the gdiplus addon Bill and all the work you're doing in the graphics area. GDI+ does seem to be slightly faster than the cairo setting, but still quite a bit slower than J602 wd.
Timings on Windows 7 32-bit for ( 'surface' plot +/~ 1 o. i: 6j99 ) are as follows: J701 Using GL2Backend_j_=: 0 takes ~2.2 seconds Using GL2Backend_j_=: 3 takes ~2 seconds J602 Using wd takes ~0.1 seconds Also, from my testing it is necessary to edit the GL2Backend_j_ setting in ~config/base.cfg and restart the J system to successfully switch from one backend to the other. Just resetting GL2Backend_j_ doesn't seem to change the graphics engine used.
