Rockstar๐
Top SchoolTommy Walton is a Principal Software Engineer specializing in real-time graphics and rendering, currently shaping the player experience for Teamfight Tactics at Riot Games. Over a 12+ year career spanning Microsoft, Amazon, Rec Room, and open-source work on the Open 3D Engine, he has delivered cross-platform rendering systems, dramatic performance wins (for example GPU morphing that dropped 277ms to 0.2ms), and practical engine fixes that preserved backwards compatibility for creators. He combines hands-on shader and compute work with technical leadershipโsetting platform budgets, driving memory reductions, and coordinating multi-discipline teams to ship features across consoles, PC, mobile, and VR. Known for finding subtle root causes (physics regressions, flipped bitangents) and turning prototypes into shipped systems, he balances pragmatic tradeoffs with innovation to move projects from concept to production.
