Vegas World makes extensive use of your browser features and computer hardware meaning performance can vary widely from system to system depending on the combination of hardware and software you have. If you have regular problems keeping Vegas World running that have lasted for days, or weeks or more, then it's probably something more serious.
Lag can cause problems for an individual or region, often for several hours but seldom for longer than that.
If you're only having problems intermittently, it's likely a temporary problem with your connection to Vegas World, often referred to as lag. Due to the pandemic, internet connection speeds aren't as reliable as normal, and it is fair to say Vegas World doesn't handle that as well as simpler games and sites. There are no serious problems on our end. I'm very sorry we cannot make Vegas World (or any of our games) run better for an individual than it does already.
