This: VideoCore VI graphics, supporting OpenGL ES 3.x I think there will be an improvement in the following emulators: n64 dreamcast playstation (beetle-hw) All require GLES 3.x for full support Will this affect Recalbox in the future?: Buster will release with a 32-bit userland, as backwards compatibility for all previous models is important. The Pi 4 kernel uses LPAE but eventually we'll ship a 64-bit kernel. PS: Possibly more performance in MAME with 2 or 4 Gb of RAM (i think)
