I'm not sure if this is totally accurate or not, but it's something to consider...
To me "Sim Speed" is the speed at which your cpu can process the game and calculate all the damage and movement and everything else going on and it probably doesn't reflect much on how well it can render the graphics, which is mostly performed by the gpu.
So if I had to guess I'd say you have a fairly decent cpu in your laptop, but your graphics card in there is abysmal. You can try lowering all the graphics settings, but at only 3fps right now it doesn't look too good.
