AFAIK, there is no change in how it works in 4.5 (vs. prior 4.x versions) and renaming groups are known to affect what you call the "reliability" of the cache. The cache can be flushed with the -F switch as you already know or better still, by deleting the reg key. Basically it is the same as your request to switch it off.
You could of course, also change the frequency of the cache flush rather than flush it on every logon.
