YouTube’s ‘Candyland’ has shared a graphics comparison video between STALKER 2 and Stalker: Clear Sky. Candyland tried to use similar scenes in this comparison, therefore this video will give you an idea of STALKER 2’s graphical improvements.
STALKER 2: Heart of Chernobyl is using Unreal Engine 4 and will take advantage of both Ray Tracing and photogrammetry. On the other hand, Stalker: Clear Sky used the X-Ray 1.5 Engine.
Unfortunately, Candyland used the vanilla version of Stalker: Clear Sky for this video comparison. And, to be honest, it would have been better if they used STALKER Clear Sky Remaster. STALKER Clear Sky Remaster adds Ultra HD Textures, 4K skyboxes and modern visual effects like Global illumination and high-quality ambient occlusion. Additionally, it overhauls the game’s vegetation with bump mapped leaves and new HD textures. It also reworks the game’s particle system with particles collision, adds custom weather, and introduces soft shadows/grass shadows.
Now keep in mind that Stalker: Clear Sky came out in 2008. That’s over a decade so it’s no wonder that its sequel looks so much better. Still, I believe this is a video that most STALKER fans will find interesting.
STALKER 2: Heart of Chernobyl will release on April 28th, 2022.
