Its not about having issues or not having issues, its about how much performance you consume for the GUI alone.��
I have installed both CPU performance monitor for 2.0GHZ Core2Duo iMac and my new i5 ��3.2 Ghz iMac. Moving a system browser window in the old iMac spikes the CPUs to 50-70% while moving the window in the new iMac is down to 20%. Of course the old imac is 7 years old the new one is 5 months old.��
The question here is "does it really worth doing something about it ?" .
��Sure if you a creating the new CryEngine in Pharo it would be a major problem or any 3d game app that taxes even modern CPUs. But for non demanding usage even if pharo community does absolutely nothing this 20% will shrink down to 10% then 5% , 2.5% and eventually 1%. This has been also a major argument point for cpython. People used to complain A LOT about cpython's performance in old cpus, cause lets face it in some scenarios and many scenarios it was a BIG problem BUT nowday those voices are getting more and more quieter because CPUs have become insanely fast and there is no indication this will stop now.��
So on the subject of whether we need GPU accelerated GUI at large as a community I would say "Definetly Not" ,Morphic is messy enough as it is, lets not make it more complex..... please !��
I am not saying that GPU acceleration does not have its merits, I am using Blender for 3d modeling and its new render engine Cycles makes uses of CUDA and its SWEET , I can almost have real time rendering, not final quality , but still good enough to see how it would look in the final render. Real time rendering to a 3d artist is like live coding to a coder. Its like Christmas vacation in Santa Claus Toy Factory.��
But on the other hand none stops anyone from implementing a third party library that runs pharo headless and then uses the OS to open a new window completely bypassing morphic and taking advantage of GPU. I don't think we need to make Morphic more complex than it already is. Pharo should be first about simplicity and then performance. ��But then if you can improve performance of Morphic and yet keep it simple enough please be my guest.��
