ah yeah that makes sense, i use SharedArrayBuffers which i think duckduckgo on android might not support. the project is more of a template or a place to learn than a plug and play web table at this stage, will make a fallback to running everything on the main thread for browsers that don't want to implement SharedArrayBuffer
yeah all laptop power saving modes throttles the fps. and otherwise it's capped to your hz on your display (or whatever chrome decides is the limit) which seems to be 60
