Why does League drop from 300 FPS to 90 FPS in team fights?

League is bottlenecked by single-thread draw calls. During big fights, hundreds of spell particles saturate CPU core 0. Our optimization frees up that core completely.

Does this improve click responsiveness on champions with fast combos (Riven, Yasuo, Lee Sin)?

Yes! Reducing click-to-action input delay from 6.5ms down to 1.8ms makes animation cancels and flash mechanics feel instantaneous.

Legacy Single-Thread Draw Call Queue Stalls on CPU Core 0

Despite modern graphics, League of Legends dispatches virtually all game logic and particle draw calls through a single main CPU thread, choking in late-game 5v5 team fights.

When 10 champions cast ultimates with elder dragon and baron buffs active, CPU core 0 spikes to 100% utilization while your GPU sits idle at 25%. If Windows interrupts or background services share that core, framerates plummet from 300 FPS to 90 FPS. We steer Windows and driver DPC interrupts completely away from the LoL main execution core, configure memory subtimings, and tune direct DX11 presentation.
