Try this

pawn Код:

forward NObjectUpdate(playerid);
public NObjectUpdate(playerid)
{
    new Float:pos[3];
    GetPlayerPos(playerid,pos[0],pos[1],pos[2]);
    for(new i = 0; i < ObjCount; i++)
    {
        if(GetPlayerVirtualWorld(playerid) == Objects[i][nworld]
        && IsNObjClose(pos[0],pos[1],pos[2],Objects[i][nx],Objects[i][ny],Objects[i][nz],Objects[i][ndraw]))
        {
            if(!NPlayer[playerid][see][i])
            {
                NPlayer[playerid][nobj][i] = CreatePlayerObject(playerid,Objects[i][nid],Objects[i][nx],Objects[i][ny],Objects[i][nz],Objects[i][nrx],Objects[i][nry],Objects[i][nrz]);
                NPlayer[playerid][see][i] = true;
            }
        }
        else
        {
            if(NPlayer[playerid][see][i])
            {
                DestroyPlayerObject(playerid,NPlayer[playerid][nobj][i]);
                NPlayer[playerid][see][i] = false;
            }
        }
    }
}

Also, the general limit of SA-MP is max 1000 objects shown at once
