BAR/SpringRTS doesn't seem to know how to utilize an APU. I have an ROG Ally that I love playing the game on, but it doesn't perform as well as I'd expect at all!
On performance mode, which can handle most AAA games at 60fps, it runs BAR at about 15FPS during combat (30 when the match starts), and that's only with two teammates against Scavs or Raptors. :)
I was wondering if there was a conf file, settings, or something that could help utilize the power of an APU. I'm really getting into this game, it just sucks when I have to play on low or else it crashes. I'm calling this a bug, because I believe that 30 fps on low on such a powerful chip isn't acceptable (not blaming anyone). If anyone has any insight, please let me know!
