Trying to get everyone on the same CS 1.6 configuration

I’d like to share my situation and ask for advice from experienced gamers. Recently, our office underwent renovations, and we were sent to work remotely for a couple of weeks. In our free time, my colleagues and I decided to build team spirit and organize a small online tournament to take a break from our daily routine. We unanimously chose the good old 1.6, since it runs even on the most basic work laptops and doesn’t require powerful hardware. However, when we started downloading the game from the first sites we came across, it turned into complete chaos: each one had its own version with mixed-up control keys, third-party ads in the menu, and wonky shooting physics. For a fair competition, we needed an absolutely identical, standard client with classic mechanics. After stumbling upon one build, I went to https://csget.me/ to find out more. There, they promised a clean distribution based on a Steam license, featuring the original weapons, built-in full protection against file corruption by servers, an updated red-and-black interface, and optimized ping. The description also mentioned that the repack is fully compatible with any anti-cheat software, features a multilingual chat, and lets you choose between classic and HD character models. It looks exactly like what our group needs, but I’d like to clarify a couple of details with those who’ve already tried this version. Is the configuration really clean, with no hidden scripts? How smoothly does the shooting run at high FPS on modern screens, and does purchasing gear with the initial $800 budget cause any lag when playing over a local network? I’d appreciate any feedback!
