Nvidia has released the GeForce Game Ready Driver 572.42 WHQL, which includes day-one support for Avowed and Civilization VII and Frame Generation updates for several other titles.
Nvidia needed to modify its drivers to support the new Blackwell GPUs. It also recommended some changes in how people benchmark graphics cards, specifically related to MFG. Neither of these things appears to have been beneficial for Nvidia's latest GPUs, on the whole.
