Those latencies are middling at best. Here is the point of latency. Latency is the lag of audio do to processing or because one is using a driver that is not meant to have low latency. MME is a driver mode that is not meant to have low latency. ASIO is a low latency driver so is WDM.
Latency only matters if one is recording audio and needs to hear the output while recording for comping for example. It also effects soft synths. If you are only playing back a project that is not recording and not needing to be in sync to what you are recording than it doesn't matter what the latency is. Example Media Player has a lot of latency but it doesn't matter because its only playing back.
A DAW needs low latency due to the need to hear sound with as little delay as is possible.
Some people get it down to 2 ms or even less.
A good rule of thumb is 1 ms equals one foot away from the source. 20 ms would be 20 feet away from the speaker. Some people are more sensitive to latency than others. Thus they need a lower latency. The range of 5 to 12 ms is for most people just fine.
Also some use WDM drivers which is a Microsoft driver model that X1 supports. it has the advantage of low latency plus X1 can adjust the buffer for it from within the program. Often times when one has a choice its a good idea to try both drivers to see which works best.
With my system I use WDM because of the convenience of adjusting the latency. For me ASIO and WDM work about the same with the interface I use.
Disregard this. There is another type of latency called DNS which is part of the system of Windows. High DNS latency can cause all sorts of audio glitching in a DAW. It needs to around 100ms or lower.
It is wrong information see the post below.
