Usually, this is all about memory latency. Until the game devs are aware of this latency issue, games should be ok... but it means you need more control on CPU machine code execution, in other words, you need to ge closer to the bare metal. 100fps is 10ms for a frame (we now know 60pfs is not enough, fps must never drop below 75-80fps, but I would really target 100+ fps)
