About the RTX64 Configuration

In RTX64, a system's processors are statically partitioned so that some processors are used exclusively by the RTX64 Real-Time Subsystem and other processors are used exclusively by Windows. The Real-time Subsystem (RTSS) supports Symmetric Multiprocessing and the concept of Processor affinity through affinity masks. Processor affinity can be set for any RTSS process and associated thread, indicating a subset of processors that it can run on. Multiple RTSS threads can run concurrently on different processors.

When configuring RTX64, you must specify how many processors should be dedicated to the Real-time Subsystem and Windows. RTX64 requires at least 1 dedicated RTSS processor and can support up to 63 depending on the Runtime edition you have purchased.

NOTE: In general, it is a good practice to configure your system such that the total number of RTSS and Windows processors is equal to the total number of physical processors in the machine. This ensures that all available processors are used.

You should always boot into the RTX64-provided boot configuration unless you do not plan to use RTX64. If you boot into a different configuration and then try to start the RTX64 Subsystem, it may or may not start as expected. If the Subsystem does start, RTX64 settings may be modified and affect your previously created configuration.

IMPORTANT! You should only use the RTX64 Activation and Configuration utility to modify the RTX64 boot configuration. You should never directly modify the RTX64 boot configuration through window tools like BCDedit.

IMPORTANT! If you boot into a non-RTX64 configuration during startup, RTX64 may not behave as expected.
