The developers intend to continue supporting the game.
The creators of Tainted Grail: The Fall of Avalon returned with the January patch 1.16. They focused on improving the game's technical condition — the fight for frames continues:
Our team worked on quality-of-life improvements, bug fixes and, most importantly, additional optimization. Of course, to some extent we are limited by the game engine, but we are doing our utmost to fight for every extra FPS :D
The creators of Tainted Grail: The Fall of Avalon announced that they "managed to achieve a performance increase of 3–5 FPS on PS5, Xbox X/S and PC." They removed some unnecessary input and interface update loops.
The developers noted that they are "fully committed to supporting Tainted Grail in the long term." The plans include releasing not only technical patches; new content will also be coming.
