Overclock3d tested themselves

Conclusion
When looking at AMD's Radeon Software Crimson 16.4.2 drivers I cannot help but be impressed, while the performance gains we see here are not earth-shattering, they are consistent and apply to all of the DirectX 12 games that we tested.
While framerate gains of around 5% may not be much, they are certainly welcome, especially when it applies to minimum framerates. Remember that these changes came from the Driver alone, with no changes made to the tested games or to the hardware.
This new driver was not made to improve the performance of these specific games, but to the DirectX 12 API as a whole, meaning that these gains should be seen in all future games running on the DirectX 12 API, which will certainly give AMD an advantage moving forward.
Since the release of AMD's Radeon Software Crimson Drivers back in November 2015 I have been impressed by the progress that AMD has made when it comes to GPU drivers, releasing a new game optimised driver with every major game release and with fewer bugs or other issues than they ever have before.
It is my hope that AMD will be able to keep up this momentum and continue to release regular, stable drivers for their users, as it not only pleases consumers but leads the way towards a more competitive and reliable PC gaming industry.
AMD's Catalyst 16.4.2 driver may not set the world on fire, but it does provide API wide performance gains that will no doubt please a lot of AMD's current and future users. It is still far top early to say who offers the best GPUs for DirectX 12 gaming, but right now AMD does seem to have the advantage.
