Little feedback of using recommended by Jimmy anti-cheat Counter-Strike 1.6 client - GSClient (
https://death-game.ru/topic_4360).
I downloaded the client from this directory http://luxserv.ge/gsclient (since it had newest information). Installation and setup was easy, I just installed it in my desired directory and added my config files to folder "cstrike" and also updated the launch parameters:
-noforcemparms -noforcemaccel -noforcemspd -freq 144 -high -nofbo -nomsaa -full
Running the client with Steam was easy, I just started client and it downloaded some updates and when CS 1.6 launched I realized that client used my steamID and profile picture by default, which surprised me. In general the GSClient synchronized with my Steam Counter-Strike 1.6 and everything ran smootly. It even showed in Steam that I am playing Counter-Strike. But in the game I didn't seen any player avatar pictures in the highscore, hopefully will be seeing in the future to confirm they are using same client!
Demo of gameplay with GSClient:

During the gameplay I noticed lag view times, since I am not sure it was caused by my computer, the server or the client I checked the average FPS, which pointed out that everything seemed okay. So I'll be testing it further and hopefully will be using it as default.
Average FPS 97,65.
