We just massively reduced GPU utilization on Wormhole for a second time (as of May 12). Give it a try and let me know if you still have issues.

GPU utilization when window is full screen, 4K resolution:

Chrome:

  - Radeon: 70% -> 15%

  - M1: 65% -> 29%
Firefox:

  - Radeon: 60% -> 8%

  - M1: 55% -> 23%
Safari:

  - 15% Radeon + 75% Intel -> 8% Radeon + 8% Intel

  - M1: 75% -> 35%
A bit more detail: We're running into the limits of WebGL. It seems just rendering a white screen at 60fps at 4K resolution is enough to make people's fans turn on.

So we reduce the frame-rate when the wormhole is not warping (render every 3rd frame). We also lower the resolution and scale it up.
