Rosetta Arete has unbelievably high 3D GPU usage compared to anyone else in the game, merely switching from other characters to her model on the screen lowers my FPS severely from my 60 FPS lock down to 30ish FPS, which goes further and further down in combat all the way down to 14 FPS, and the FPS loss and GPU usage spike remains the same even if I lower the graphics settings to the lowest graphics preset, despite having a solid 60 FPS on any other character on the highest graphics preset. constructs and coatings after Veronica have all had higher GPU usage, rising from an average of 30-50% GPU usage for all characters, to 90-99% GPU usage starting from Liv Limpidity, but without an FPS drop, while Rosetta Arete straight up stomps FPS down significantly regardless of graphics settings, and pushes usage to the max constantly. Check top right of the screenshots for examples of GPU usage and FPS. Merely clicking on Rosetta in character select, and onto other characters back and forth, shows a severe spike in GPU usage, she's extremely badly optimized.
