Still happening on 16.10.1. Paracel Storm only.
Crucial information: Running an older driver (16.8.3) with DLL's from 16.10.1 in the BF4 folder make everything rock-solid stable. So if you guys can figure out that discrepancy, you're golden.
Running two 380x in crossfire. PLEASE don't make me have to choose between keeping older drivers for Mantle in BF4 and newer drivers for DX12 in BF1...
Update, all the same problems with 16.10.2, but I just realized that it is a bug with other maps with lots of water, like Operation Mortar.
