Vertical resolution of 300 gives most realistic results (up to 1000 supported)
Larger horizontal resolutions (up to 50000) allow stronger converging winds to develop, forming more realistic, longer lasting cells
Performance is mostly GPU dependent, GTX 1070 or better recommended for realtime gameplay
At high resolutions, the sim starts slowly for a few seconds so the GPU does not reset, then speeds up. You can also open Advanced → Apply Performance Preset for more aggressive speed settings
Press F3 in-sim for an FPS / debug overlay (like Minecraft)
If you have a laptop with a dedicated GPU, make sure the browser is actually using it! It's often using the integrated graphics by default
Play in fullscreen mode (F11)
