Turning this off or on may improve stability, though this heavily depends on the driver - on AMD, it's recommended to have this set to true, as Halo 3 appears to crash when if is used for flow control (possibly the shader compiler tries to flatten them). On Intel HD Graphics, this is ignored because of a crash with the switch instruction.
