Which OS you halve installed? If its steamOS use jknights build of the emulator and use kyoskis texture mod to downscale textures 25-50% the difference is barely noticable anyway. And perhaps the most important one ia no cloth physics or half cloth physics mod. After using these my performance problems were gone with legion go s. If you want 60fps use 30fpsfix patch with lossless scaling set up to 2x. Much better variant since it doesnt make any changes to game engine thus being more stable approach. Btw you dont need sound fix from bblauncher if you run 60fps with this method.
