Downsides running Live 9 in Win 8 mode, jBridge etc.?

[Harry_HH]

My DAW is based on Win 10 and Live 9 64 bit. As some of you may know, Audioease Speakerphone 2 is not working under this combination, but works well if you run the Live 9 in the Win 8 mode.
I have no problems with that, so far, but I wonder, if that has some negative consequences/downsides?
E.g. CPU, latency?

On the other hand I still have some 32 plugins, which I have bridged to my 64 DAW by the jBridge.
This seems to work very well, but I´m interested in knowing if the bridge taxes my DAW CPU resources, or affects to the quality of 32 bit plugins? E.g. if I run the same plugin as 64 bit version, or bridged 32 bit version in the same DAW, if there any difference in the speed/latency/quality of those plugins?

Compared to the actual overhead of doing audio DSP, its generally negligible.

OK, good to know if this is the case. These things are difficult to evaluate, perhaps measurement is possible with some tools.
Same concerns different authoriation software, such as iLok or Waves Central, which run in background - you keep wondering how much these tax you computer resources.
