Not sure if this has been reported already or if this is just me, but the area that's in front of Grove is pretty much impossible to navigate because the game goes through some serious slowndown for some reason. I've also experienced slowdown on the dunes area, but i'm not sure if it's just me that's going experiencing this.
Not just you. We're unsure of why this slowdown only occurs for some folks and not others.
Right now, best temp fix is to use mouse click controls, and close any other background programs you're running. Playing the game windowed might help slightly too.
