Yup Vivek
Counter Strike has 2 versions wich are as follows:
Counter Strike-Source (based on the Source engine).
Counter Strike 1.6 (based on the Half Life 2 engine).
Both of them hv same maps,same gameplay but ppl say ( who are closely related to game developers) tat 1.6 is smoother and much more responsive in terms of its highly skilled Bot nature and AI and a much more smoother gameplay as compared to the Source version of CS.
I will surely ask for a CS 1.6 (based on the HL2 engine).
BTW, wich CS do u own ?? Source or 1.6 ??
Also, do try to change the mode from D3D to OpenGL coz in my system the OpenGL works really smooth and awesome.....
Cheers n e-peace......
