PSA Calculator is a free browser tool that helps FPS players find a practical mouse sensitivity using the Perfect Sensitivity Approximation method. Start with your current sensitivity, compare lower vs. higher values, and narrow it round by round.

Free FPS PSA Calculator for finding mouse sensitivity with the PSA Method, works for Valorant, CS2, Apex Legends, Overwatch 2, Fortnite and other shooter games.

Use this PSA Method Calculator to find a practical FPS mouse sensitivity by comparing lower and higher values over several rounds. Built for Valorant, CS2, Apex Legends, Overwatch 2, Fortnite and other shooter games. Use a number you can actually test in-game. If you do not have one yet, set a temporary sensitivity that turns your view roughly one full rotation with a comfortable mousepad swipe. Use your current in-game sensitivity or a comfortable full-turn mousepad swipe as the starting point. This PSA Method Calculator starts with your current in-game sensitivity, then creates one lower value and one higher value for each round. Test both values in the same FPS routine, choose the one…from psacalculator.cc

  A new kind of FPS aim trainerJul 2026 · openaim.pramit.gg · ▲85

  I played a lot of Valorant and got mad, so I made an aim trainer that analyzes your raw crosshair movement to explore your raw motor and perceptual weaknesses instead of scoring scenarios. It also chooses sens and difficulty as part of the tasks, and makes playlists that are optimal difficulty for you to learn and progress faster!

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
