We measured this on mid and high-end rigs running Fortnite and only kept the tweaks that moved 1% lows, not just the average FPS counter. Here's what survived testing.
Stop thermal throttling
Performance that vanishes after ten minutes is almost always heat. A throttling CPU or GPU silently drops clocks mid-match.
Tune a custom fan curve so the card ramps earlier; a few extra dB is worth steady clocks.
- Custom fan curve — ramp earlier, not louder-at-the-end
- GPU undervolt for cooler, steadier clocks
- Verify case airflow: intake front/bottom, exhaust top/rear
- Repaste if temps climbed over the last year
Lock your GPU control panel
Driver-level settings override in-game ones, so a misconfigured control panel quietly caps Fortnite. We standardise these on every build.
Low Latency Mode set to Ultra (NVIDIA) or Anti-Lag (AMD) shaves real input delay when you're GPU-bound.
- Power management → Prefer maximum performance
- Low Latency Mode → Ultra (or Radeon Anti-Lag On)
- Texture filtering → Performance / High performance
- Disable in-game V-Sync; cap FPS just under your refresh instead
Verify it actually worked
Never trust the average FPS number alone. Watch 1% and 0.1% lows and frame-time consistency in Fortnite — that's what 'smooth' really means.
Run the same replay or aim-trainer routine before and after, capture with a frame-time overlay, and only keep changes that flatten the graph.
- Benchmark the same scene before/after
- Track 1% lows, not just average FPS
- Watch the frame-time line — flatter is better
- Change one thing at a time so you know what moved the needle
