Think about it: our russian friends may not not be able to ask for hints to make progress because of the language barrier. Of course it is frustrating to get stuck.
Then those folks just need to ask in their native language, in this case Russian. Over the time since I'm a member here, we had several threads where ppl did so because they don't speak English well enough. And there are always ppl who answer in their native language, be it because they are natives of that country or just speak that language well enough. Problem solved in no time.

May disable most visual options. So, i read, that someone running DooM III on GeForce 2 MX440. And other says "Still game requests too much for medium quality graphics".
You MUST be joking. I know that Russians often have crappy/outdated computers (after all, most aren't rich), but you cannot be serious in asking the TDM/FM makers to lower the graphics quality to a level where you can play this game with at least medium settings. I already think that most models are too low ploy and that anyone who has a fairly modern rig should be able to play with 5 times as much polygons and still have good enough fps. But I'm fully aware that there are folks out there who don't have a fast computer, so I don't comlpain.
I think, mappers try at least make FM. And forgets make this, to player understand - where go next. Character always silent, but may be say "I need key to open it", "I'm need on top" or "Aha, this room". Play like game "Go there, do not know where, Find something I do not know what.".
This is definitely something to ask the FM makers for. Well, why don't you? Ask in Russian, someone will translate it. Or you ask someone (like MoroseTroll) who can translate your request, so you can post it yourself. I'm sure someone will pick it up, since it shouldn't be that hard to implement.
