The Witcher 3's Blood and Wine expansion adds a beautiful new area, Toussaint. Tom shows this region presented at its very best - at a 3840x2160 resolution (or 4k) at maximum settings on PC, as running on a GTX 1080. 4K performance on this card is 45-50fps region for The Witcher 3, and so we've capped our captures at 30fps..
