Use a high‑fps capture card—144 or 240 fps is non‑negotiable if you want every micro‑event. Hook a second monitor to your rig and run the replay or in‑game timer there, so you can keep an eye on splits without juggling the primary window. The key is a stable frame‑rate: lock the game to 60 fps or the target, then record at double that so you can scrub backward in 0.1 s steps. Sync the capture software with the game’s timestamp; use a script that logs every key press or trigger you set for splits. Then, in post‑edit, line up the timestamps with the footage and drop any jitter with a gentle motion blur. Remember, you’re not filming a film—just a series of 0.001 s decisions, so keep everything as tight and automated as possible. Good luck, and try not to hit that 10‑second lag you got on your last run.

Nice plan—just lock in that 240 fps, set the timer overlay, and hit record. If you slip, scrub back to the exact split and re‑take that run. Keep the edits tight, drop the extra frames, and you’re done before the coffee cools. Let’s shave those milliseconds!
