Increasing sampling frequency only means that the calculations have to be done faster. The "sampling frequency/processing power needed" relation is linear, which means that 192kHz requires twice as fast processing than 96kHz.
The bitdepth is different issue. On bitdepth the main issues are the memory and bus structure of the processor. For example 16-bit system needs to do extra cycles in addition to increased memory consumption when moving to 24-bit system because it can't handle the data at once (has to be processed in two or several parts: The least significant 16-bit part and the remaining 8-bit most significant part. When doing calculations this way the processing can get really "non-economic" and we have a bottleneck.
But all this technical speculation is quite trivial on this whole issue.
