It seem You are right. Sorry, my bad.
For some reason, I noticed that the game starts in three possible ways: 1 - Runs in full performance. 2 - Runs at approx. half the "full" performance with short severe framerate drop when changing weapons. 3 - Exactly as the bug description (constantly switches between running full speed and slowing down to a crawl)
I just probably been /really/ lucky with constantly getting the 1st one for a whole week; giving me a false impression of the bug no longer being present.
