Question about 64-bit Double Precision Engine

Why are you turning off the 64bit engine?  (I always leave mine ON.)  Are you running into some CPU issues or some other limit where you need to turn it off?
 
It gives better sound and more headroom since the intermediary results of internal calculations for reverb, compressors and other mixing algorithms don't get truncated to fewer bits (which leads to lower sound quality).
If you don't believe me, here's the official CW word on this:

Hope this helps!

LOL it should be checked on. LOL

When you say checked off one thinks you turned it off. Though the use of off is in fact correct in this context.

One reason we are here on this forum is to learn about these things and to pass them on to others.

This was well discussed when the 64 bit audio engine first appeared.

Then there was far less confusion due mostly to how few had a 64 bit system. Now things have changed greatly and we see confusion about plugins and audio engines and internal processing.

Its hard, I believe, to be up on everything unless you spend a lot of time reading.

OK I have it on for export. I also use dither because I always export to 24 bits. All my audio files are at 24 bits unless I am going to place them on a CD then I export to 16 bits with dither.

OK, now I'm confused.  We are talking about 64-bit floating point as opposed to 32-bit floating point, are we not?  Certainly that's going to provide better precision.  But more headroom?  Less chance of clipping?  How do you run out of head room (in any practical situation) with floating point?  Nevertheless, here's what the cakewalk link above has to say:
 
"The 64-bit Double Precision Engine provides greater resolution, meaning more accurate audio reproduction and more headroom. You'll especially notice the benefits of the 64-bit Double Precision Engine when working in large projects containing many audio tracks and plugs-ins. Your chances of clipping will be significantly reduced." 
 
I'm pretty sure this has been discussed here before and the consensus was that with either single or double length floating point, clipping was not going to be an issue until of course you convert back to binary.  Even with that conversion, coming from double length is not going to give you a reduced amount of clipping compared to coming from single length, right?

64 bit gives you more data to be able to use which allows for more headroom.... you are limited based on data steam size and 32 bit is limited to a certain headroom.. it is a mathematical calculation and it does make sense thinking of it in that way, however  I believe I answered the original question above.... unless I am somehow mistaken, which does hapen from time to time...

I will Check it off in the pop up box

 
There you go again! LOL  Your statement is ambiguous.
I think you mean to say you will check it ON...

It explains how 64 bit mixing affects quality and performance.
