Doom: TDAInput lagid Tech 8

Fix input lag in Doom: TDA

Work through these in order — they're sequenced to find the cause fastest, not alphabetically. Most input lag cases in Doom: TDA resolve by step three.

1
Turn on the vendor latency tech

NVIDIA Reflex (or AMD Anti-Lag 2) is the single biggest input-latency win in supported titles — it can cut total system latency by 20-40%.

2
V-Sync off (use a cap instead)

Classic V-Sync queues frames and adds tens of milliseconds. Use an FPS cap just under your refresh rate plus VRR (G-Sync/FreeSync) for tear-free play without the queue.

3
Exclusive fullscreen where the game offers it

Borderless adds a compositor hop on some setups. If the game has true fullscreen, it's the lower-latency path.

4
Check your monitor's game mode + cable

TVs and some monitors ship with processing that adds 30-100ms. Game Mode bypasses it. Use DisplayPort/HDMI 2.1 at your panel's native refresh.

5
Mind the frame-gen tradeoff

Frame generation doubles displayed FPS but adds latency — fine for visual smoothness, wrong for competitive play. Keep it off in ranked.
