RealBrowser system requirements
Note: RealBrowser protocol capacity for parallel VUs is strongly linked to the availability and speed of the CPU. Consequently, if you run your RealBrowser test at scale, ensure that the LG host is free from other processes that may take CPU. Some antiviruses and antimalware can impact CPU usage too, especially in Windows environments.

Browser versions
NeoLoad includes the latest browser versions with each new release. This means that when you upgrade your NeoLoad version, you are generally up-to-date with the latest browsers available.
You also have the option to specify a path to an arbitrary (non-bundled) browser of your environment. However, at replay time, there is no guarantee that this option will work and that issues will not arise - use with caution.
Note: When using the latest Chromium browser, you are effectively 2-3 major releases in front of the Chromium version that is wrapped by the latest Chrome version.
