I have a very powerful laptop, but unfortunately with a very poor graphics performance, so I use GeForce now, and have always wanted to play Minecraft with ray tracing, but I have no idea how or whether this is possible at all. I practically use the Founders Edition of GeForce Now.
Minecraft Raytracing will only be released for the Bedrock version of Minecraft and is not yet available
There are already graphic mods for Java edition
GeForce Now can do RTX (but you also need Premium), but you would have to install Minecraft Java Edition with a graphics mod that can do ray tracing.
But since you can't change the files on GeForce Now, it doesn't work
No, it does not exist
There's still no graphic mod that RayTracing can
SEUS PTGI (Path Traced Global Illumination) for Optifine
As far as I know, can also use the RTX cards for improved performance
The SEUS PTGI shader doesn't have much to do with ray tracing, as the name suggests, the global illumination is simply solved via path tracing. And so that it also runs on weaker cards, most of it is calculated via the CPU. You can call it ray tracing… But you shouldn't. Correct ray tracing will only be available on the bedrock version for the time being
Correction: Can't use the RTX cards because Optifine has no connection to the graphics engine for the RT cores
[.] [R] ay tracing describes a process where a scene's geometry and information is queried by shooting rays and seeing how they collide with the scene. Ray tracing alone usually involves firing a single or few rays to render effects like hard shadows and reflections.
Path tracing is an application of ray tracing, where typically many rays are traced to gather more information and render more advanced lighting effects, namely Global Illumination. Instead of tracing one light path for a shadow or reflection, the goal of path tracing is to calculate the many potential paths that light can take in a scene, in any direction, with multiple bounces.
Path tracing thus includes even more information from the environment in the calculation.
It is very similar and uses the same technology.
But it's not ray tracing
Ok, I have to add something here: You can set ray tracing with the PTGI shader
