There are many reasons why this might occur. They range from your viewer settings to your connection to the internet itself. Here are few of the top things to check and try. Sometimes a cache clear and relog will fix things for you. Go to "Avatar" at the top of your viewer, then choose "Preferences", then the "Network and Files" tab, then the "Directories" tab and choose "Clear Cache"....and then relog. Your bandwidth setting may also be causing issues. If this is set too high or too low, it can have a severe affect on your experience. Somewhere between 1000 and 1500 is recommended. Any higher or lower will have detrimental effects. You can check this setting in "Preferences"..."Network & Files" tab. The slider at the top shows you what your setting is. A wireless connection is not recommended for virtual worlds. This type of connection can cause some data to be lost in transmission due to packet loss. Please connect your computer with an ethernet cable to avoid issues. A Hypergrid visitor will have a slower connection than a local user. Waiting for a bit, to allow your assets to load may help. Try teleporting to another region within the grid and then come back. A relog may be necessary. Check your connection/ISP...you may be suffering from slow internet speeds at the moment. These are just a few things that can have an affect on your experience.
