2023 was a brilliant year for advancements in video game graphics - and up there amongst the most astonishing achievements was Remedy's Alan Wake 2. In this extended interview with the Remedy tech team, Alex Battaglia gets the opportunity to ask the developers literally anything and everything he wants to know about - from mesh shaders vs primitive shaders, to the team's approach to ray tracing through to the game's threading model, it's all here... along with how the team scaled Alan Wake 2 to deliver the goods on Xbox Series S.

00:14:35 What research was done for mesh shading?
00:16:30 How do you handle geometry across the platforms (PS5 vs. Xbox vs. PC)?
00:17:53 How is indirect lighting achieved without hardware ray tracing?
00:19:19 How does ray tracing mix in with the traditional rendering?
00:22:36 How is the game's BVH managed?
