Valorant, Riot Games’ competitive 5v5 tactical shooter, launched globally on PC in June 2020, arrived in China in mid-2023, and expanded to Xbox Series X/S and PlayStation 5 in August 2024. Since its release, Riot has shipped new updates roughly every two weeks, maintaining a steady live-service cycle.
The shift to Unreal Engine 5 focuses on improving development workflows without changing the core gameplay experience. Riot designed the upgrade so players wouldn’t notice visual changes or mechanical differences, but the internal improvements are significant. Performance, stability, and development speed all benefit, allowing Riot to deliver more content consistently while ensuring Valorant retains its competitive identity.
Tools and Technology Driving Valorant’s Future
The move to UE5 emphasizes tools that boost productivity rather than flashy graphics. Riot gains access to Unreal Insights, an advanced profiling system that replaces their older, custom-built solutions. Developers can now track performance, optimize resource usage, and debug systems much faster than before.
Technologies like Zen Server and Multiprocess Cook reduce build times, helping teams iterate on updates and features at a much faster pace. Riot is also evaluating Horde, a collaborative build tool designed to streamline production across Unreal Engine titles. For UI development, switching to the new UMG view model removes the need for Riot’s legacy solutions, speeding up interface creation.
These upgrades allow Riot to produce content more efficiently while maintaining Valorant’s smooth, competitive experience. While players won’t immediately see visual enhancements, the tools set the foundation for faster content delivery and improved long-term performance.
Performance Gains and Chaos Engine Challenges (Unreal Engine)
Riot’s engineering team faced challenges during the migration, particularly around physics. Moving from PhysX to UE5’s Chaos physics system risked changing gameplay behaviors unintentionally. To solve this, Riot developed automation tools that record gameplay at the 128-tick server rate. The system compares UE4 and UE5 data side by side, flagging any mismatched behaviors for debugging.
This rigorous testing process ensured mechanics like movement, abilities, and hit detection behave exactly as they did before the upgrade. On top of that, tools like Zen Loader and UDOD enhance load times, while optimizations to Iris improve server performance and reduce latency during high-stress scenarios.
Though Riot avoided introducing visual overhauls, many players may notice improved frame stability across different platforms, especially on mid-tier and lower-end hardware.
Development Efficiency and Player Experience
Valorant’s live-service structure means updates must continue during significant engine changes. Riot handled the UE5 integration by creating a dedicated Perforce branch, where developers resolved merge conflicts, fixed compiler errors, and stress-tested new workflows before merging into the mainline.

Far-future content developers were brought into the integration branch early, helping identify issues across different scenarios. Once testing stabilized, Riot merged the branch into the mainline build and released the UE5 upgrade as part of the regular patch cycle.
From the player’s perspective, the transition is seamless. Gameplay feels identical, visuals remain consistent, and performance is slightly better on most setups. Behind the scenes, however, Riot gains faster iteration cycles, better debugging tools, and stronger workflows.
Additionally, Riot used this upgrade as an opportunity to audit Valorant’s core systems. Risky experiments were removed, validated optimizations were kept, and several low-level systems were refined for efficiency. This future-proofing ensures Riot can deliver faster updates and larger features without compromising competitive integrity.
