So far all of the games that are using the ReShade ray tracing shader mod by Pascal Gilcher look great, these games include Crysis recently and other ray tracing-style mods like SEUS powering Minecraft. But now one of the best examples of a ray tracing shader mod are here with Grand Theft Auto V.
GTA V is a great looking game with mods applied but with ray tracing shaders it looks out of this world -- the lighting effects are actually bloody impressive. At the 2:00 mark the reflections on the glass table and floor look absolutely incredible, but it is the 2:21 mark when the sunlight is hitting the green Lamborghini and as the sun passes over the cars it lights up the white Lambo next to it with the reflection of green light, with the effect looking super-realistic.
The developer explains his methods: "What I'm doing is ray tracing in screen space, tracing rays against the depth buffer (a data buffer that contains the information how far an object is away, as opposed to the color buffer which tells you what color the object has and what you usually see in any game). When compared to DXR, it has several limitations: anything behind another object does not contribute, anything outside the screen does not contribute, backfaces do not contribute. The benefits of this shader is that it can run on every game and GPU and it's a step up from regular SSAO. I hope this serves as a sneak peek at what DXR ray tracing can do and why everyone in VFX can't wait to get real ray tracing for their games".
You can support the ReShade mod on its Patreon, with a $20 per month tier including access to the GTA V ray tracing shader mod.
