Hey Guys,
for all the poor guys who still are working on the problem with a slow framerate although having a proper PC system (and running it with XP):
Start NBA 2k10
Go through your menues (load/quick game etc...)
Start Game
when the pre-game presentation starts, ALT+TAB to go back to Windows
Press CTRL+ALT+DEL for the Task-Manager
Right-Click on nba2k10.exe
SET AFFINITY(right below "SET PRITORITY")
Uncheck CPU 1 --> OK
SET AFFINITY
Check CPU 1; Uncheck CPU 0 --> OK
SET AFFINITY
Check CPU 0 --> OK
Back to NBA 2k10
after some seconds the game will run smoothly.
FYI my system: XP SP3
AMD Athlon 64 X2 Dual Core Processor 5000+ (2.61 Ghz)
2 GB RAM
NVIDIA GeForce 8800 GT (driver 27 Sept 09)
Settings: Res 1680:1050
VSync On
MSAA: 4x
MSAA quality: 6
Crowd: med

Stadium: high
Sideline Characters: on
texture q: high
dept of field: on

Benchmark: 55 FPS !!!
I hope this helped some of you...
