Kappa Shader v4.0

  • Kappa 4.0 and Patrix' Resourcepack
After the massive update that was Kappa Shader v3.0, here comes the next one thanks to a broad set of new OptiFine features that have been added since then.
This update is once again an all around improvement, and much more refined than 3.0 or 3.1 were. Not only has the performance seen a massive uplift (approx. +25%), but the visual results have also improved by quite a margin with respect to that. This is thanks to many improvements done to the lighting (especially the SSPT has recieved a considerable improvement as you will notice yourself when comparing it to 3.x) and the atmospherics, with the latter now utilising temporal upscaling for improved performance and quality.
Many smaller quirks have also been ironed out with auto exposure being one example, which should behave much more consistent now and gives you precise control over the weighting of bright and dark spots.

An important change also is the absence of a Lite version of 4.0, as such a version is now obsolete thanks to the much more scalable and optimised internals of 4.0, so all you gotta do is switch to a lower profile now.

Only 1.16.4+ is supported at this moment since the new OptiFine features have not yet been backported! Also needs OptiFine G7 or newer.
