Golem.de has made a claim that AMD Ryzen Threadripper 2990WX benchmarks are held back by a faulty Nvidia driver. It seems that some games run at half speed on the 32 core beast compared to its 16 core 2950X sibling when running an Nvidia Geforce GTX 1080 Ti GPU. When the Nvidia GPU was switched out for an AMD Radeon RX Vega 64, the frame rate increased substantially and in some cases the frame rate doubled. After switching from the Geforce to a Radeon RX Vega 64 (test) , the frame rate rose dramatically in four of the five games tested, sometimes doubling in size. Only Assassin's Creed Origins runs on the Threadripper 2990WX with the AMD card as slow as before. We asked Nvidia if the driver problem is known.
