Performance for DX11 using Vermintide 2 crossfire profile on AMD driver 18.3.1 is crap and reduces performance when looking at smoke and fire. solution is to use Witcher3 profile which has near flawless performance and outperforms the proper profile for Vermintide 2. issues with witcher3 profile include minor flickering of some shadows or torch like effects, which aren’t very intrusive for enjoyment.
