I noticed this problem to be present also with CUAC's but in a lesser amount.
I have an average 125 ping so that shouldn't be much of an issue, and I checked and it was stable during those times.
P.S. : a side question, are the same servers that host games also are used to download the patch data? If so It might improve after most finish downloading it.
