Allright, thank you very much for taking the time to test it again and to reply to me. Further optimizations are still needed, we hope to be able to fix this mouse issue in the next update.
Hope you manage to fix it! Just yeah beyond playing the game and seeing it happen I have no idea how one would fix it lol. Maybe it is the frame rate but I did watch the particles very closely and yeah they seem smooth regardless. Def test this.
