Hey guys so here we go.. some results of my testing. Just to be clear, I´m running Y500 with i7, 8GB RAM and GT650SLi with 310 drivers (314 are crap so far) - no OC.. so far :D 
Anyways, here are results with my current setting 
Fullscreen 
1920x1080x32 
Visibility : 5000/3000/200 
Rendering: 
Rendering resolution 100% (FHD) 
VSYNC on 
AA disabled 
PPAA: SMAA Ultra 
ATOC: disabled 
Postprocessing: Very high 
HDR: Standard 
AF: Ultra 
PIP: Ultra 
Dynamic lights: Ultra 
Quality: 
Everything on high, only textures are very high 
FPS are about 25-35, mostly around 30. 
I´m testing this in mission editor with spawning myself in some camp on the hill (cant remember name of it) and runing/looking on everything.. I´m pretty sure that I would need to tweak it a bit for using in multiplayer modes, bud it shouldt be an issue.. Biggest FPS killer is distanance but there is not much difference between 3km and 5km in terms of view, but it is about 5-10 fps. AA is just killer.. More information about MP tweaking and OCing later on ;)
