Movement is smooth and highly responsive. Therefore, our client/server communication is designed around the idea that a server must never trust a client’s view of the world. Note: VALORANT uses a server-authoritative networking model to limit the types of cheats possible. The challenge: Design client/server communication to limit the attack surface area for cheaters.
This means preventing cheaters from ruining games and minimizing unfair advantages for players with better hardware or networks. We want any player who chooses to spend their time mastering VALORANT to see their investment pay off. A Few VALORANT Design GoalsĪs with many challenges in software development, building a competitive tactical shooter involves making tradeoffs across many (often competing) design goals. Let’s briefly cover some of our goals that relate to netcode and competitive integrity, and afterwards we’ll take a look at some of the technical challenges we had, and how we resolved them in ways that amplify these goals. If you'd like to read about other technical topics, please take a gander at our articles on anti-cheat and shader implementations. This article will first explore the design goals we had in mind when building VALORANT’s netcode, and then dive into technical challenges and how we addressed these to align with our design goals.
Playing VALORANT should feel like a natural extension of a player’s ability and skill.
We take competitive integrity to mean that the outcome of each match is decided only by the planning and execution of the players in the game. The internet, game client performance, Riot's servers, and other players’ machines should never get in the way of providing players with a level playing field in each match. We’ve made many big bets with VALORANT to accomplish this, and one of our biggest is our ongoing investment in competitive integrity. We’re Matt deWet, gameplay tech lead on VALORANT, and David Straily, project tech lead on VALORANT - and we're beyond excited to be here with you all to share some of the technical details behind how we’re addressing some common issues in the FPS genre - peeker’s advantage, poor hit registration, and simulation divergence.įrom the beginning of VALORANT’s development, we’ve had one guiding priority for all the decisions we make - what do players want, and how do we provide that in a way that feels satisfying?įirst person shooters are what we call a "red ocean" opportunity space. There are dozens of phenomenal games in the genre (many we grew up playing) - any shooter offering made by Riot needed to really differentiate from the others to live up to our expectations.
