Tripwire Interactive has released a beta build of Killing Floor 2 that supports PhysX FLEX Gore Effects, and YouTube’s ‘r1cko’ has shared a video showing those effects in action. In a test map (with just a few enemies) Killing Floor 2 was running with 40-60fps at 1080p with an NVIDIA GTX 960 SC 2GB. You can view the video after the jump!
