IMPORTANT :

All R 1 products work ONLY on Intel CPUs (X/XE and Xeon CPUs are NOT supported)

Windows 11 is NOT fully supported (Meaning, if you have windows 11 it may not at all work with R 1 , and you may have a lot of crashing / BSODing issues)
What works the best on Windows 10 Pro from 1909 and later.

Please refer to the official website for product description as they can change often
