Yes the two are the same... It's the same game only on different servers... Also some information you might want to know is that the game doesn't work properly with mice that have polling rates of anything over 500 or even 400, if you are experiencing any form of jagged movement or any sort of weird mouse maneuvers then I strongly suggest you drop your polling rate to around 250hz or something along those lines... That's the only real way to make sure your mouse is moving smooth, straight and proper like it should... Also if you need a reference game then I suggest you turn to cs1.6... It has the same sort of view models and the same feel to it in general so maybe that can help in making up a formula for crossfire.
Also I too can confirm that there is no steam version of this game.
Another thing you might want to know is that the mouse engine of the game is REALLY old... Which is why it has problems with the high polling rates, plus that is also why there is a lot of acceleration in this game, sadly you cant really do anything about it aside from dropping the sensitivity to make it feel at least somewhat natural.
Hope I helped in some way.
