Overview
Without a fix, the game renders at 16:9 inside a wider screen (PCGW calls it anamorphic 16:9 with letterboxing), so you get black bars. Flawless Widescreen (dedicated plugin) or the SUWSF ultrawide mod fixes this. PCGW notes the crosshair can be slightly off with FWS.

Patch history & verification
Current Steam build (specific build number not confirmed)Sep 23, 2026
FWS module 'Assassins Creed IV: BlackFlag' confirmed in the repo. PCGW marks ultrawide 'hackable' and WSGF rates it 'limited'. The exact look of the black bars without a fix and how cutscenes/menus behave with fixes are lower-confidence and set conservatively. Steam API gave no release date; 2013-11-19 is the PC launch date.
