Pyvtron VX - The Very Realistic Version of Pyvtron Shaders

Details

Features: Volumetric Fog, Water Caustics, Fancy Water Texture, Extremely Realistic Rain + Sunlight Appears Sometime In The Rain. If you don't believe, try Pyvtron VX!

Performance Impact: High or Medium If You Have A Good Computer.

You can find older versions and the official releases of Pyvtron VX here (My Website)

 

Requirements

AMD CPU (Recommended)
Nvidia GPU (Recommended)
A graphics card that supports OpenGL 4.6 or OpenGL 4

Note: I currently only have access to Nvidia GPUs for testing. I cannot make sure if Pyvtron VX works on Intel CPUs and AMD GPUs.
