Follow-up Comment #14, bug #53845 (project octave):
(ver421 seems 2x faster than ver 441 for repeated plots after first, but its
in the noise)
Including the opengl32.dll workaround and tested with a 480x640 uint8 BW image
on Win7 Pro Intel i7 32Gb Nvidia Quadro M2000M;
pic1=imread('001183.png');
tic;imshow(pic1);toc
Results:
Octave421 1st 'imshow' in 0.8sec, thereafter consistently at 0.15sec for
repeats
Octave441 1st 'imshow' in 0.4sec, thereafter consistently at 0.33sec for
repeats.
...
Thank you for supporting Octave!
