Okay ... this is not actually newsworthy in terms of Star Explorers, but maybe you might be interested.
I found this article about an RTX shader this guy is working on. The images have a few free shaders as well as the not free one, all activated through "reshade." The article describes how to do it.

This will work with any game, not just Star Explorers. The shaders I used here include ambient occlusion, bloom, HDR and the RTX one described in the article. I feel like it adds a nice bit of realism to the game, but it does have a strange interaction with some of the menus. Nothing game breaking, but a few strange visual artifacts...
