Hey!

It's not a real problem, but something strange ... I already noticed that in TMUF, but here it's worse

My PC is 2 year-old, it's a laptop, from HP. The shop said it was made specially for games ...

So, why do I have to put the settings at Very Fast (not the shadows, the advanced settings) so that my game flows well enough, and doesn't lag? It works with Fast as well, but it's a bit less flowy.

Do you have any tip to make my computer more powerful?

there are not many things you could do with a laptop...
* clean it from inside;
* update drivers;
* clean Windows (unnecessary files, viruses, reinstall if you don't mind).
which gfx card do you have?

I don't know. What is gfx?

GFX Card = Graphic Card.

GraPHiCS

How can I know?

On your computer's package. Or on your computer's brand website.

if you don't know such things about your computer, then it's clear why shop assistants told you it's a gaming computer ^^

Don't get it why I can play tmnf easylie on high settings but tm2 no more with middle/low settings.

joy..: There isn't much what you can do, clean your hard drive or update your graphic driver..

@rev: turn off 2d/3d decals + set water/car reflections to low, this will improve performance a lot
