Here is a very strange thing....dunno if anyone has any ideas... I noticed that the big poly demo runs at around 30fps after a bit of optimising... not bad... I can still get a bit more though.
I then noticed than when I used VNC to montor the outout visually on my PC, the frame rate....doubled.... yes doubled... thats damned odd I thought.
so I set it up to run on my pi4, via monitor and yup, around 30fps.... run VNC as well, adn....60fps.
wtf... is this some x11 madness? I'd like to get to the bottom of this..
BTW here's the Pi3b+ doing the exact same demo, the only thing I had to change was to reduce the texture size of the emission textures as it was 4096 for the Pi4, too much anyway.
resolution is a bit different its 1080p/2 (basically rendered to dispmax as half res and stretched. so 960x540) usinv VNC on this actually slowed it down a few frames, which is more what I'd expect
