If GR is "compatible" with QFT, the claimant is an idiot.

Newton

Special Relativity

Quantum field theory

General Relativity's physical systems are always spatially separable
into independent components. Systems of three or more particles
require cluster separability (macroscopic locality).  When the system
is separated into subsystems, the overall mathematical description
must reduce to descriptions of the subsystems.  This is vital in
scattering problems with two or more fragments.

Quantum mechanics allows entangled states (superpositions of product
states) that require a fundamental irresolvable connection within
readily demonstrated physical systems (two-slit diffraction, the
Einstein-Podolsky-Rosen paradox).  Macroscopic locality is violated:
Measuring the state of one slit in a double slit experiment alters the
observed diffraction pattern to single slit patterns (quantum eraser
experiments).  

Relativistic and quantum views are incommensurable.

General Relativity models continuous spacetime, going beyond conformal
symmetry (scale independence) to symmetry under all smooth coordinate
transformations - general covariance (the stress-energy tensor
embodying local energy and momentum) - resisting quantization. 
General Relativity is invariant under transformations of the
diffeomorphism group.  General Relativity predicts evolution of an
initial system state with arbitrary certainty.  

Quantum mechanics' observables display discrete states. Heisenberg's
Uncertainty Principle limits knowledge about conjugate variables in a
system state, disallowing exact prediction of its evolution.

Relativistic and quantum views are incommensurable.
