That paper measures our margin of error when syncing to a perfectly predictable rhythm, not our ability to detect system latency. Applying that to an FPS doesn't really work for two reasons. First, enemies are erratic, meaning you are mostly relying on your reactive visual-motor pipeline, which is bottlenecked by ~150ms anyway. Second, even for purely predictive shots, your brain subconsciously calibrates out fixed hardware lag. I'll concede that pure prediction absolutely exists in FPS games-like tracking a falling player with the LG in Quake 3 or landing a predictive mid-air rocket. In such cases smoothness of high FPS helps, but adding a 1ms drawing delay to those 500FPS (what the article is about) won't be noticeable at all because your brain naturally calibrates out constant hardware delay. |

So yes I agree over time you wouldn't be able to tell 1 ms from 2 ms, but a skilled player doing back to back comparisons might be very different.
