Quake Live itself doesn't really work that well in widescreen resolutions regardless of FOV. I know I and a few other aimers play 4:3 letterboxed even on ultra-widescreen monitors due to the extreme levels of fish-eye (or whatever the proper term is) present in widescreen regardless of FOV making it unreasonably difficult to properly judge distances. I hear from some that Quake Champions has similar issues and is better played in 4:3 if you want to aim your best, though I can't say since I've only played QC a few times.
Still, I don't need it to be perfect for Apex even if I play it on ultrawide, I just need it to be good enough so that I'm not completely wrecking my muscle memory. Assuming 4:3, would it be about right? I've played some target shooting in Apex and found that the further in I zoom the more it feels like my cursor is moving too slow. This is what I've got for my config so far.
cl_fovScale "1.42857" (100 @ 4:3)
mouse_sensitivity "0.962121"
mouse_use_per_scope_sensitivity_scalars "1"
mouse_zoomed_sensitivity_scalar_0 "1.1006366127883664"
mouse_zoomed_sensitivity_scalar_1 "1.2577175152712603"
mouse_zoomed_sensitivity_scalar_2 "1.315247519056545"
mouse_zoomed_sensitivity_scalar_3 "1.3363129172868717"
mouse_zoomed_sensitivity_scalar_4 "1.3516755792116053"
mouse_zoomed_sensitivity_scalar_5 "1.3571166143275724"
mouse_zoomed_sensitivity_scalar_6 "1.3596464793180723"
I know scalar_0 is only going to be accurate for one set of weapons no matter what I do, but eh. For comparison, my QL settings.
seta m_cpi "1200"
seta cg_fov "100"
seta sensitivity "10" (10 degrees per cm for 36cm/360)
All other relevant settings at default with zoomfovs between 17.5 and 75 depending on weapon (they all feel the same aimwise).
