SEUS PTGI is an experimental version of SEUS that includes a totally custom software implementation of ray tracing that does not require an RTX graphics card and will work on any NVIDIA graphics card (though low-end cards may struggle with performance. AMD compatibility is still being worked on). The “PTGI” in the name stands for “Path Traced Global Illumination”, which is the main feature of this project. It also includes ray traced reflections.
SEUS PTGI is still very much in an alpha state, and therefore is not yet ready for public release. However, if you’d like to support the development of this project and would like to test out experimental versions, head over to my Patreon page for more information.
