mousefix ? m_Accel 0 ? 500 hz ?

Are you using cnq3? m_accel or something is the command for it in that

try using one of the registry fixes like cpl mousefix

i got the same problem, i got cpl mousefix, m_accel 0, but still fells like accel is on :(

m_filter 0
cg_oversamplemouse 0
in_mouse -1/1/2[direct input exe]

also, most likely r_swapinterval. check out in your gfx driver options for any weird shit and turn it off (Iike forcing vsync)

oh and r_finish 0 or 1, try this out as well.

but reinstall gfx and mouse drivers in the first place (if you have default win drivers then do nothing)

if you're confused with all these options you should check out what's EXACTLY your problem. sometimes it feels like acceleration but accel is not problem. first of all check if you have any accel actually. just measure cm/360 or cm/180 moving veeery slowly and then faster. if values doesn't differ much acceleration is most likely not the case. then:

1. m_filter 0 if your pointer feels "smooth", a little bit like moving on ice.
2. swapinterval and fucked up drivers if pointer feels laggy
3. in_mouse 1 is stable, in_mouse -1 is a little bit more "sharp"
4. r_finish 0 or 1 if your pointer feels slightly laggy.
5. cg_oversamplemouse shouldn't cause any problems at all, but set it to 0 just in case...
