Three port-only knobs, each defaulting to byte-identical behaviour: - Video.FovScale (D211): multiplicative half-angle scale on every perspective projection matrix as it is loaded (gfx_apply_fov_scale, gfx_pc.cpp). Columns 0+1 scaled together so H/V FOV widen uniformly and aspect is preserved; ortho (HUD/menu) matrices untouched. Composes with the game's per-frame aim-zoom rewrites for free. Percent of vertical FOV, 50-150, default 100 => guarded early-return (zero FP ops, golden dumps byte-identical). WIDESCREEN-FOV-PLAN Phase 4, landed standalone. - Video.Anisotropy (D212): expose fast3d's already-implemented GL anisotropy hook as config (1-16). New gfx_set_anisotropy_level() extern-C wrapper clamps to the GL max. Default 4 = the value fast3d already hardcoded => no delta. - Video.DisplayFPS (D213): PD-parity top-right FPS readout, sampled once per emitted frame (optionsoverlay.c fpsTick). Config-only; default 0 => emit still returns NULL with the panel closed. F10 overlay gains 'Anisotropic' and 'FOV scale %' rows (DisplayFPS is file-only - the panel is at its 13-row layout limit, matching PD). Build clean (ntsc-final); bunker1 framediff worst_cell 12.219 vs 12.221 baseline = render noise, no-op confirmed. Interactive eyeballs owed (see docs/HANDOFF.md M-83). findings.md: D211-D213 rows + index regen. WIDESCREEN-FOV-PLAN Phase 4 and QOL-INVENTORY rows marked done.
