Perfromance: CPU100% in OpenGL mode on a big map when computer does not have GPU even the graph is static

[jiajun]

Current Behavior

Our machine is for industry which using Intel Xeon without GPU. We created an application based on pixi v7.4.2 in the default openGL mode. When opened a big map (including more than 60,000 rects), the CPU becomes always 95%-100%, even after the map rendered without any movement.

Expected Behavior

The CPU usage should go down after rendering or moving the map.

Steps to Reproduce

let me know if you need a sample.

Environment

• pixi.js version: v7.4.2
• Browser & Version: Electron 25.2.0
• OS & Version: e.g. Windows 10

i would try bumping to v8 - thous should run static content much faster!

couple of other approaches:

• render the view to a texture - and if nothing moves, just keep re rendering the texture to the viewer.
• add culling so you only render what you see
  hope that helps!
