I've tried that, and the ANGLE2 renderer is like +2 fps better than the gl2 renderer, but it's still pretty bad. I'm not exactly sure what changed between 7.3 and 7.4 renpy that makes it essentially not use the GPU.Note sure if you tried switching Graphic settings in RenPy or not. Shift-G at the opening screen (or start the game holding down the Shift key), and select the last (lowest most) selection. That has helped me at times. Good Luck!
