1/ Displaying 2000 static sprites.
2/ Displaying 2000 transparent static sprites.
3/ Displaying 2000 rotating sprites.
4/ Displaying 20 static text.
5/ Displaying 20 dynamic text.
So we who love visual studio will be forced to use something else in order to get great performance out of sfml? I'm currently experiencing the same performance issue as the one above.
Another workaround is to use only std::wstring and not std::string to prevent call to String::SetText(std::string) (actually the bottleneck into this method is conversion between string and wstring because SFML String handle only wstring) and use String::SetText(std::wstring) instead.
void String::SetText(const std::string& Text)
{
myNeedRectUpdate = true;
if (!Text.empty())
{
std::vector<wchar_t> Buffer(Text.size());
#if defined(__MINGW32__)
// MinGW has a bad support for wstring conversions (and wchar_t based standard classes in general)
mbstowcs(&Buffer[0], Text.c_str(), Text.size());
#else
std::locale Locale("");
std::use_facet<std::ctype<wchar_t> >(Locale).widen(Text.data(), Text.data() + Text.size(), &Buffer[0]);
#endif
myText.assign(&Buffer[0], Buffer.size());
}
else
{
myText = L"";
}
}
int main()
{
sf::String myString("Test");
__int64 l;
for(int i = 0; i < 10; i++)
{
l = __rdtsc();
myString.SetText("Blabla");
printf("New SetText : %d\n", __rdtsc() - l);
}
for(int i = 0; i < 10; i++)
{
l = __rdtsc();
myString.SetTextOriginal("Blabla");
printf("Original SetText : %d\n", __rdtsc() - l);
}
getchar();
return EXIT_SUCCESS;

Well, there's no mean to "split" community, however, there definitely *are* people who don't speak french or english.
And it's no problem to switch between french/english(/german) wiki and forum if one wishes
Sometimes, it's just easier to use one's mother tongue.
