Specifically, ray tracing (or path tracing) relies on having access to the geometry in a scene, and runs ray/triangle intersection calculations to help determine shadows, reflections, global illumination, and more. ReShade injects a DLL into the DirectX or OpenGL libraries to provide access to frame color and depth data, but ray tracing normally needs a lot more than that. ReShade typically applies post-process filters to improve the way a game looks-adding SMAA to remove jaggies, SSAO for more realistic shadows, depth of field effects, and more. It's still a bit unclear as to how this particular filter accomplishes its magic.

Once the player has spawned into either a randomly generated world or a preset map called Navezgane. After each day has passed the zombies get harder to defeat and become even more aggressive towards the players. But an older game like Crysis seems like the perfect playground for such shenanigans, and EuroGamer / DigitalFoundry put it to the test-in co-op mode, just to take things to the next level. 7 Days to Die is a zombie hoard crafting survival game were the primary objective is to survive for as long as possible. Yes, any compatible game can in theory add global illumination, not just Crysis. If you own DayZ on Steam, you'll also own DayZ Experimental, so you can help Bohemia Interactive test future versions of the game.Thanks, Rob.Grab your own D. Pascal's ReShade filter (in alpha form-you have to be a Patreon backer to get access) attempts to apply path traced global illumination to games. Our guide to ray tracing goes into more detail about what it is, how it works, and the various types of ray tracing that can be used in games.

Path tracing and ray tracing use similar concepts with differences in the specific techniques.
