x86 version vs. x64 version

[LaciBacsi]

I notice that the x86 and x64 versions are updated at different times. I have them both installed on my PC. Is it best to always use the most current version, regardless of whether its the 32 bit or 64 bit version to ensure you are getting the latest decryption methods? For example, the latest x86 version (10.0.7.9) says it offers decryption for new java methods. I would assume this is not yet offered in the latest x64 version (10.0.7.7). Frankly, I notice very little speed difference between the x86 or x64 version, so I always use whatever the newest version is, regardless of 32 bit or 64 bit. I assume the speed difference would only be noticeable if using 'software only' decoding/encoding (which I don't use since it causes my i3770K CPU to run very hot with stock fan). Can you shed some light on this and offer any suggestions. Thanks

I use the x64 for the speed increase unless I need a feature that is not fully ported over from the x86 version yet (or for updated protection).

Ok thanks.
