Since I've been coding my game for a while, I hadn't really noticed this, since I guess I got used to it, but c_tracing with the following causes 'jerks' in the movement?

Code:

while(1)
{
  //movement code and stuff here
   c_trace(my.x,vector(my.x,my.y,my.z-30),IGNORE_ME|IGNORE_SPRITES);

This seems curious; does tracing cause that big of a slowdown? The fps is unchanged, and I need to use c_traces (actually more then one in some situations), so this poses a problem.

EDIT: Problem solved, not c_trace after all

Ugh, chalk this one up to stupidity; I had multiple vector calculations running every frame, instead of a single frame like I intended. Problem Solved.
