For best experience working with VisionProject, we recommend using a resolution of 1440x900px, or better. 1366x768px can be used, but in maximized web browser window and with some zooming.
Some browser plugins, like Firebug for Firefox can cause a significant slowdown in VisionProject, so we recommend turning off those features while working with VisionProject.
Do not use the browser back and forward functions, use the navigation possibilities inside VisionProject instead.
Use Internet Explorer 9 or newer. The performance compared to Google Chrome, Firefox, Safari or even IE9 is quite bad.
