Yeah that TOR engine really needs some optimizing. Go watch some warzone footage...it's sad really how little that engine can do. Why did they go with that engine for an MMO is beyond me.
TOR Engine is absolute shit. It's a poorly designed engine in the first place. It's horribly optimized. Why it's so freaking technically intensive despite the graphics not being that fantastic is beyond me. Everything from a technical standpoint reeks of laziness and lack of talent from the development team.
