[Octave-bug-tracker] [bug #53845] Octave too slow when plotting large arrays with QT graphics toolkit

[Markus Mützel]

Follow-up Comment #1, bug #53845 (project octave):

Octave 4.4.0 for Windows uses software rendering by default via a opengl32.dll
shipped with Octave. Earlier versions used the system's opengl32.dll which
turned out to be unreliable with graphics cards drivers from many different
vendors.

You could try re-naming opengl32.dll that you find in the "bin" directory
where Octave is installed. That should make Octave pick up the system's
opengl32.dll (as previous versions did).
Does that make any difference with respect to performance? (It does for me.)
