Your fix is a hack, not a fix, let's get that right for a start. If you look at the code around it, you'll see that m_iv_angEyeAngles sets up interpolation on m_angEyeAngles, which is a networked copy of a player's eye angles which is sent to everyone but the local player. In C_HL2MPPlayer, the interpolated version is used in ::PreThink and ::EyeAngles also has an override. This makes eye angles in spectator interpolated (ie. smooth) and is Valve's way of implementing this. You probably derived from CBasePlayer or CBaseMultiplayerPlayer and didn't set this up, which again isn't an engine thing.
