I have the same problem! Winfows 8.1 and Radeon R9 285. The AMD website states it has latest drivers for this OS/gpu version 17.7.1. It is the best it suggests. Seems Amd drops support for win 8.1.Hovewer Oculus rejects to work with 17.7.1 driver and asks for "latest".How may I solve the problem?
Windows 10 with graphic card r9 380, driver v126.96.36.199 but oculus wont start because driver v17.11.2 is not installed !
