Russian version review

[adonys]

As far as I saw, the stutters might be caused by sounds/effects.

Disable all sounds (from config file), and give it another go. Then try again without/lowest effects.

Now, if this proves right (as it seemed to me when I've tried it yesterday, but I only have a crappy laptop in here in London, my computer monster sits at home in Bucharest), then this, corelated with what Oleg said about multicore/multithreading (that only the sounds are actually made on different threads), then it means we are in front of poor multi-threading programming (stutters caused by the main process waiting signal clearance from threads finishing their job).
