Draw(Text) performance issue

I read the road map and I noticed this:

Done - ready for next version
- SYSTEM Added types and conversion functions to handle all Unicode formats
- GENERAL SFML now uses UTF-32 for all text related stuff instead of UCS-2

Will this speed up the SetText-method for visual studio that you were talking about earlier or is it something else?

Actually, the performances issue with strings was a stupid thing which is fixed.

I'm also going to improve the sf::String rendering code to optimize it, but it's already way faster than before.

It definitely got faster. I got 5000 fps before, now I get 24000 fps.
I almost thought that there was something wrong with my message box rendering code. :P

OMFG ! You work on a Cray XT5 ? =D

I confirm, string is now a lot faster than before.

Nope, it's a 8800GTX, rendering nothing but a message box (only a few lines of OpenGL code) + fps string in a 320x240 window (it drops to an average 15000 fps if I change the resolution to 640x480).
Don't worry, it gets slower the more I draw on the screen. :wink:

Sounds great. So I don't have to change any of my code to get this speed up, only download the new source?

@Dabo :

Yeap, maybe you'll need to do some changes on your code with the new unicode stuffs. If you don't use wchar at all, just update your svn.

Hi Sir.
Yesterday I try svn source but without different results.
I just put svn include/lib dirs into sfml 1.3 sdk and recompile all.
I'm using VC9.
Now I'm working using wstringstream.
