Just before picking up TF2 a break, I stopped using mouse accel in quake engine games (cpma and qw) in order to become accustomed to its absence in the source engine.

After some digging around some commands came to light which seem to quantify accel – m_customaccel_*.

It would be great to be able to play with a similar setup to before, but the problem is I can’t figure out how to convert accel between engines. While transferring sensivitity is the trivial task of keeping a set length per 360, measuring accel is proving more troublesome.

In q3 & qw I used m_accel 0.1 and after trying various values for exponent, scale and max I failed to reach anything remotely similar.

If anyone knows how I could solve this either post it up here or pm me on irc/steam, it would be much appreciated.

Thanks in advance.

This is just an assumption here as I know nothing about how these commands work in TF2, but it would make sense that m_mouseaccel1 and m_mouseaccel2 determine the point (or mouse movement speed) at which a multiplier of mouseaccel kick into effect.

From Wikipedia:

“For example, versions of Windows prior to Windows XP doubled reported values above a configurable threshold, and then optionally doubled them again above a second configurable threshold. ”

In XP and later OS its not simply a doubling effect, but these commands in TF2 might be for that purpose, so try leaving the second one at zero and mess around with the first, see if that gets you anywhere.

Also as far as I know (but I may well be wrong on this) the same accel setting will have a different effect when using different dpi and/or different screen resolution. Maybe try setting screen res to the same you have in Quake if it’s not already?

Yeah JH, those guys aim like shit :D

Appe, are you serious ?
Are you actually using mouse acc. ?

Well, I guess it might be good if you are used to it then.
If I use mouse acceleration and try to turn around I seem to be looking in a completely random direction afterwards. It must be very hard to get used to the acceleration.

good old Pjonkan in my old team used 12 sens with normal mouse acc if i remember right.

lol Jh ;]

Also thanks for the help KOVACS, I guess I’ll have to do a little more digging into this than I had planned to it. If I do make any grand discoveries I’ll be sure to post them here (don’t hold your breath though).

In fact one of the most intersting points of accel was that it was directly affected by m_pitch/yaw, which is why so many players tweaked those values when it seemed superficially redundant to do so.

i.e. http://www.esreality.com/?a=post&id=1370847 (math-phobes look away now)

I’m using bybben’s cfg, but cant understand few commands:

m_side “0.8”
m_yaw “0.022”
m_pitch “0.022”
m_forward “1”
m_customaccel “0”
m_customaccel_scale “0.04”
m_customaccel_max “0”
m_customaccel_exponent “1”
m_mouseaccel1 “0”
m_mouseaccel2 “0”
m_mousespeed “1”

These give me the most worry, becouse they’re mouse (am I right?) settings. Can someone clarify atleast some of those?

Dunno about logitech, razer has an option to turn it off though ;)
