OK guys, i don't know if this helps everyyone, but it sure helped me:
In %appdata% roaming/2k15 folder there is a file called VideoSettings. I changed refresh rate to 50 and my frame rates gone up and there is no more stutter!!!
My configuration is
i3 2310 M 2.1 ghz
4gb RAM
Nvidia Geforce 555 M
my framerate is very playable: 40 FPS on 1080p resolution and smooth as silk...on cutscenes it drops to 30, but there is no lag.Before i changed refresh rate i had a big lag and fps in the low 20's.
textures and players are on medium, shader is on high...special effects off...it looks better than unmodded nba 2k14 if thats you're interested in.
I'm very happy that now i can play this game even with my 4 year old laptop.
I guess the game is not optimised well, but let's hope that patch will improve things.
