Hi. Thanks for the feedback. And thanks for taking the time to test different quality settings on your setup. It's really useful. I'll keep trying to improve on the performance (like maybe dropping shadows at lower quality settings), but unfortunately Firefox is generally slower than Chrome when it comes to WebGL (see WebGL performance tests for Chromium vs Firefox). Which browser you prefer is obviously a personal choice, but it would be interesting to see if Chrome makes a difference for WebGL games on your setup. Thanks again for the feedback!
