Hot on the heals of the 4.16 preview release, Epic have released a hotfix for the 4.15 branch. The major purpose behind this fix is to work toward resolving D3D Hung crashes while enabling additional NVidia GPU diagnostics. To support these new diagnostic features however, you need to update to a newer NVidia driver. More details on the GPU Hang bug are available here. This hotfix also addresses the following issues:
