That does not forbid nVidia from hiring decent translators.
And, BTW, were the software open-source, you could correct the messages for them to make sense..
Say 消除鋸齒 to computer geeks in Taiwan and they'll understand it without difficulty. Say it to non-computer people, and they won't get it... just as English-speaking non-computer people won't understand "anti-aliasing".
Assuming you're not talking about languages used by aboriginal groups who don't have computers, how could you translate a term "well" and yet come up with something that makes little sense?
In portuguese we tend to use the english words for technical terms and jargon, sometimes slightly corrupted to fit the grammar. Terms like delete, debug and commit are conjugated in as if they were regular portuguese verbs and used frequently even with acceptable translations existing. Delete in particular is quite common even among non-technical people.
For many technical terms, specially newer ones, I can't even think of any acceptable translations without it sounding silly. Most of the time they are left as-is and you need to know the jargon to understand the translation.
I much prefer to read technical documents and books in english.
