  In this paper, we obtain the asymptotic behavior at infinity for viscosity
solutions of fully nonlinear elliptic equations in exterior domains. We show
that if the solution $u$ grows linearly, there exists a linear polynomial $P$
such that $u-P$ is controlled by fundamental solutions of the Pucci's
operators. In addition, with proper ellipticity constants, $u(x)-P(x)\to 0$ as
$x\to \infty$ (see Theorem 1.11). If $u$ grows quadratically, we obtain similar
asymptotic behavior (see Theorem 1.16). In this paper, we don't require any
smoothness of the fully nonlinear operator.
