I love Acrobat DC. It is the best PDF handling tool I have ever work on. But it is not as smooth as Windows' Edge. it is 32-bit Application which creates problems while we use it on 64-bit Windows 10. You must change its architecture to 64-bit. it does not handle heavy PDF with ease and that much of smoothness. it always got stuck and freezes the windows.
Please upgrade it to 64-bit.
I love your faith that 64 bit will solve everything. What evidence do you have to suggest that a bigger address space will make any difference?
