" Added a new cvar for adjusting the look speed while zoomed: pm_zoomedSlow (defaults to 100). This can be adjusted from 1 to 100: lower numbers are slower. "

Does anyone know what the value is to get Q3 feel?

depends on what zoomfov u had i q3

I was under the impression that the ratio it downscaled the sensitivty by was constant no matter what cg_zoomfov you had set.....

Are you sure it depends?

When using +zoom in Q3, the sens is scaled down by a factor dependent on your zoomfov and on your resolution's height to width ratio.

You can convert Q3's zoomsens to Q4's pm_zoomedSlow using this equation:

pm_zoomedSlow = (8/3) * arctan( (h/w) * tan(zoomfov / 2) )

I designed this equation to be evaluated using degrees, not radians. It's simpler this way.

where

h = Resolution height
w = Resolution width

(for most people (h/w) will be equal to 0.75)

Woosh :D

or you could if you got zoomfov 45
ratio = 45 / 90 = 0.5
pm_zoomedSlow = 100 * 0.5

corect me if im wrong

Although that is a little crude, yes it will give you a good approximate ratio to within 5 percent, so it may be good enough for most, but I sense that some will only be satisfied with the exact value.

Actually, if you use radians, small angle approximations and assume a 4:3 screen ratio, you get a better approximation, which is ironically:

pm_zoomedSlow = zoomfov

which is very accurate for zoomfov below 70.

Ok well I used cg_zoomfov "45" in quake 3 and 640x480.

Well in your case you would have pm_zoomedSlow = 46, which is pretty damn close to the approximation above.

According to your earlier equation, shouldn't the zoomedslow value be 41 or something for him?

No, it works out to be 46. Be careful with the brackets:

(8/3) * arctan[ (h/w) * tan(zoomfov / 2) ]

oh sorry, I missed the *outer* brackets.
But anyway, shouldn't it be affected by the fov you use? =/

Yeah it should, but it isn't. :)

Weird =P

i use fov 60 and sens 2 (without zoom its 3) in q3, is a pm_zoomedslow value of 66 the same ?;)

Yes if you use a custom zoom by changing fov then you have to scale your own sens, so 3 to 2 would be 66% (or rather 67% to be more accurate).

However if you use +zoom AND manually scale your sens, then you have to combine both reductions, which would be 42% in this case.

Wth is arctan?

arctan = Inverse tangent = tan^-1

If
y = tan x
then
x = arctan y

Ahh, ty :) In school we always called it inverse tangent, not arctan, so the word I were unfamiliar with the word :)

And q4 will not crash when i use this?

no :)

injx, could you tell me plz what pm_zoomedslow value would be the same for zoomfov 45 and res 800x600 in q3. cause i never been succesful in math classes at school :))
