Mouse sensitivity
Settings puts one Mouse sensitivity slider above Field of view and the audio controls. It spans10..300% in10% steps;100% retains the prior 64 angle units per raw mouse count. Sensitivity defaults to100% for fresh settings, Clear Data and migrated saves. The same value controls both axes; changing it does not enable vertical aim when GBA or autoaim disables manual pitch.
The grid uses language row16; mouse label/bar32/40; FOV label/bar56/64; music style88; music volume96/104; sounds volume112/120; Back144. Bars share X32..176 and percentages start at184. English/German/French use the same layout. Pointer adjustment and keyboard arrows use the same range and value mapping.
ssa_pc_input_sensitivity sets one positive coefficient for yaw and pitch.
Runtime settings apply rounded64*(percent/100) units/count. Accumulated input is neither replayed nor
rescaled when settings change. Yaw wrapping, pitch saturation, focus handling,
menu suppression and the original autoaim policy remain intact.
Preferences v18
The record remains16 bytes with CRC32 over bytes0..11, stored at12..15. The
compact header is ASCII SSA followed by version18. New payload:
- Byte4: music style bits0..1, renderer2..3, display4, HUD5, aspect6.
- Byte5: music volume0..6, automap7.
- Byte6: sounds volume0..6, jump7.
- Byte7: FOV offset0..5, vertical aim6, third-person7.
- Bytes8/9: equal mouse slider values0..29 (percent=(value+1)*10). Existing two-axis v18 files migrate to the horizontal value in byte8; byte9 is still range-validated and both bytes are made equal on the next save.
- Byte10: in-game NETRICSA0, enhanced weapons1, bobbing2, surface decals3, water reflections4, mipmapping5, godrays6.
- Byte11 and unused high bits are reserved and must be zero.
Versions1..17 retain the prior decoder, with mouse sensitivity default100%. All earlier renderer, FOV, audio and extras migrations remain unchanged. Older executables reject v18 rather than silently reading the new payload as legacy preferences.
Validation covers equal axis deltas/defaults/limits, all30 slider values, unequal v18 migration, legacy migrations, invalid records, keyboard/pointer edits, native application, Windows preference persistence and localized menu screenshots. No campaign playthrough is required for this settings/input change.
