What in_mouse values do you use in QL?

i got in_mouse 2

I think that's most likely to be the reason it's different then, because your sensitivity value is presumably (numerically) different.

You could turn on m_showMouseRate in Q4 and cl_showMouseRate in QL and see if you can figure out what is going on.

m_accel is like 10x faster imo.

try m_accel 0.01

feels slower for me actually

there's m_accel in quakelive?

no

lol
