I've had 2 hard lockups in Shadow of the Tomb Raider with these drivers. Everything set to max with DX12, RTX on, and DLSS on. Also had two instances of 0x887A0005 DXGI_ERROR_DEVICE_REMOVED error messages at start up. I'm not getting the device hung message with these drivers anymore, but I suspect that the hard lockup replaces that. This was while playing and just running around towns, did not happen while benchmarking.
