yes, buy a new pc

yes, you have to get a new pc, make sure you spend AT LEAST 500 dollars on it, this will improve performance. also, make sure you dont have a vpn, web proxy, or any kind of security active, also, turn off your antivirus as windows really doesn't like classicube that much and will try to block it at all costs. also dont forget to download as many plugins for classicube as humanly possible, to improve your playing experience. download. every. plugin. also, save every world you visit, so you can take them with you on long trips or if your wifi goes out.
