in CL_CreateMove add
------------
if (cvar.ltfxspeed>1)
{
double* globalTime = (double*)0x028048A0;
*globalTime += frametime * (cvar.ltfxspeed/5);
}
add the cvar as a float
------------------
instead of
if (cvar.ltfxspeed>1)
{
double* globalTime = (double*)0x028048A0;
*globalTime += frametime * cvar.ltfxspeed;
}
