Hello,

Hello all of you.
PLEASE.......
I need to know that which Game will run on my pc with best performance.My System info. is below:

Intel[R]
Celeron[R] cpu 2.13 Ghz,
1.99 GB of DDR Ram
64 MB Intel graphics Controller Video card.
WINDOWS XP SP3

I already played these games with best performance.

Max Payne1,
American Mc'gee Alice,
GTA Vice City,
Hitman 2,3,
NFS Porsche,
IGI,etc

Hitman was Nice i like it

Most of the Games meet my system info still they are running in slow motion.I am so stacked about it.

for example: L.A.Street Racing
this game meets my requirement but when I started the game It plays in very slow motion whats the problem????
Tell me any Game like Hitman (or any racing games) which will run without slow motion on my pc.
.

THANK YOU IN ADVANCE!!!
Hope,U will give me a best answer!!!
