3D viewer perfomance seems to be slowed down since the latest releases #215

the FPS drops and it even drops more when showing the populations

@tarelli I've closed all my chrome windows and restarted chrome now the performances seems to be excellent. can you try it? If you still have issues can you then try to see if you are using the GPU and GPU raster? press F12 (developers tools) then if the "Console" is not showing press Esc. Click on the 3 vertical dots menu in the Console and select Rendering enable Frame Rendering Stats. Now you should see a small Frame Rate dialog. Is the GPU raster on?

I have around:

60 fps when no populations are on
50 fps when populations are on and I'm relatively zoom out
40 fps when populations are on and I'm in the middle of a large amount of cells.

GPU raster: on Nvidia Graphics: GTX 1050 Brave Browser (chromium based)

@zsinnema Please let me know if this are the same values that made you create the card or if you are experiencing something different.

Currently we do 2 things to improve performance:

Manually reduce meshes complexity
Use of InstancedMesh to draw the cells

40fps is still good enough

Experiment V1_V2a shows performance issues in the 3D Viewer. Most likely due to the great amount of cells. We need to investigate
