As it was the case with earlier releases of Radeon Software Crimson Edition drivers, the new one also comes for Windows 10, Windows 8.1 and Windows 7 operating systems, in both 32-bit and 64-bit flavors as well as support for all AMD Radeon graphics cards since the HD 7700/HD 7900 days.
In addition to the optimizations for those two games, especially the quite popular Battlefield 1 Open Beta phase, which had some server problems earlier today, the new Radeon Software Crimson Edition 16.8.3 drivers also bring a fix for the random blank or colored screen problem seen on some Radeon RX 400 series graphics cards in certain games.
There aren't any other updates in the new Radeon Software Crimson Edition 16.8.3 driver but the release notes list quite a few known problems in various games.
