tell by my face lol
you would probably be turning down shadows to low or off. the game uses CPU to render shadows. you would be probably turning down flora and terrain down. on 1366x768, probably medium graphics and medium textures, maybe high if you can handle it.
but why not download the game and give it a go? you can never rely on other's stats. you want to get into the game, sit in a big battle and optimize your game settigns according to yor hardware
Tried the game out, got 10-15 FPS with everything at lowest settings. So that sucks.
