The cursor movement seems to be a bit delayed?

Try to enable the "Enable system cursor" option in the settings, which can reduce the delay of cursor feedback. However, some operating systems or browsers may have problems such as flickering or inability to display the cursor, so it's turned off by default. In addition, the current cursor size adjustment of the hardware cursor is only fixed to 3 levels, the smallest value is displayed below 0.65, and the largest value is displayed above 0.95.

The game is freezing/very choppy what do I do?

You can uncheck "Use system resolution" in the settings and set the resolution to a value lower than 100%. It is recommended to avoid high CPU usage, close other tabs of the browser or close other applications. Please make sure you are using a mainstream modern browser (such as Firefox, Chrome).
