As said and included in the update news, the Geforce 552.12 WHQL Game Ready driver adds optimizations for the new Call of Duty Season 3 update as well as the recent Diablo IV Ray Tracing Update. In addition, it adds GFE Optimal Settings optimizations for a couple of games including Dragon's Dogma 2, Desynced, Horizon Forbidden West, Skull and Bones, and others.
The new driver also includes a single fix for Horizon Forbidden West, which adds a proper Resizable BAR profile. There are still several known issues including the one with lower GPU utilization in Horizon Forbidden West when Reflex is set to "On + Boost".
