Bug Blog: TFT Bugs and Patches

In this article, I’ll be describing how we handle patches across PC and mobile for TFT, and how this relates to quality assurance. Later, I’ll tag in my engineering counterpart, Gavin Jenkins, to give a super techy point of view on patches, and we’ll dive into two use cases that demonstrate different types of patches and how we deploy them.

Keeping Legacy Software Alive: A Case Study

Hi all, Brian "Penrif" Bossé here with a fresh batch of gory, nerdy details surrounding an outage for League. Today we'll be going through why the EU West shard was out to lunch for just over five hours on January 22, 2021. We don't always write these things up - they take time to do and the reasons for outages aren't always that interesting - but this one was particularly painful as it was quite long and on the heels of some other, unrelated outages so figured it'd be worth a dive.

Scalability and Load Testing for VALORANT

When VALORANT was still early in development, we had high hopes that in the future we’d launch with high initial popularity. From the beginning, we prioritized scalability to make sure we could support the number of players we were hoping for. Once VALORANT entered full production, we began working in earnest on a load test framework to prove out our tech. After many months of work, we successfully ran a load test of two million simulated players against one of our test shards, giving us the confidence we needed for a smooth launch. This article explains how we load tested our platform, and how we tackled the scaling challenges we encountered along the way.

How Riot Games Uses Slack

I’m Byron Dover, engineering manager for information technology at Riot, and I lead the team responsible for developing enterprise software at Riot - or as we sometimes call it, Riot’s Operating System. I’m excited to share a look at how Riot integrates with Slack to support the game development lifecycle.

Technology Interns in 2020: League of Legends, TFT, & VALORANT

The Riot internship program helps technical players drive their professional growth by embedding them on tech teams and having them contribute to impactful, exciting technology projects. Last year we published an article by some of our interns, giving readers a glimpse at the projects technical interns get to work on. We’re doing a follow-up this year, but with additional sections to reflect our new games. 

There were so many interns excited to contribute to this article that this year we’ll be doing a 2-part series. Intern stories are sorted into categories - the first post (this one) includes all blurbs for League of Legends, TFT, & VALORANTand the second post focuses on General Game Tech & Tooling/Infrastructure.

VALORANT Shaders and Gameplay Clarity

Hi, I’m Brandon “mochi” Wang, a software engineer on VALORANT’s Content Support team. I’m specifically going to focus on shaders, which are an essential part of computer graphics, my area of expertise. Shaders are the programs behind what most people consider a game’s graphics - how a program running on your GPU takes in scene/game data and creates the pixels seen on screen. I’m excited to talk about this because the intersection of engineering, art, and design is a personal passion of mine.
