The issues are mainly under high CPU load. A RT kernel will continue to maintain low latency without xruns but a normal kernel may not. The compromise option is full preemption which generally does a good job but doesn't have the issues with throughput that can occur with a RT kernel.

Although maybe you meant full when you indicated a preemptive kernel (voluntary preemption is still the default I believe but it's kernel dependent).
