Why CS:GO won't be supported anytime soon Posted the Wednesday 25 July 2012 by Didrole

I've been asked a few times if I plan to add support for CS:GO into DBlocker,
and the answer is no, at least for now, let me explain you why.

The engine fork that CS:GO uses is a huge step backward from a security / cheat point of view,
all bug fixes that have been applied to the TF2 engine since something like 2008 haven't been applied to the CS:GO engine (and that's a ton of bugs)
Trying to fix all these myself in DBlocker would be a waste of time, because some of them require clientside modifications, the others would require plenty of hours of reverse-engineering and testing,
for something that Valve has already a fix for in the others games.
This version of the engine also bring its own new issues:
The sv_pure is even more broken than on the TF2 branch (and can't be fixed without a complete remake since there is no GCF nor FileSystem_Steam).
The VPK implementation allows easy material hacking that can be accomplished with a simple hexadecimal editor, while preventing true modding such as custom HUD, models, etc.
The Debugging of the client (which I often need to do) is harder because the CEG will try to prevent it.

This is far too much reasons for me to not support CS:GO and I had already not much interest in it.
Feel free to post you comments about this article in this topic.
