SetFramerateLimit does not seem to work correctly

[novemberdobby]

I get this too. I got the latest SFML build today, and this is what happens:

Code: [Select]


//stays fairly constant at 60fps but very visibly stutters every few frames
EnableVerticalSync(true);
SetFramerateLimit(60);

//stays very loosely around 60fps (around 50-80), but runs smoothly
EnableVerticalSync(false);
SetFramerateLimit(60);


oh and also, the first bit of code works perfectly in Ubuntu 11.10 without stuttering.

I'm having a strange issue with this new commit however should I post this on the sf::Time thread? But since it's somewhat related, I think I'll post here.

When I open an SFML application it starts with 66FPS but after a while they drop to 32FPS and it stays there. Even if I restart the application the FPS doesn't change, I have to restart the computer.

What could be causing this? Driver issue?
I have an ATI Radeon 4870, latest drivers, using Windows 7.
Compiled with both debug and release, static library.

Any SFML application?

Yeah, compiled with the new commit I mean.
I think it might not be SFML's problem though. I just found that this happens only after I play the game Portal 2. So I'm going to guess a driver problem. I'll try a full driver cleanup and reinstall.

EDIT: I just remember I had this problem before:

Shame on me! Although I'm not using vsync this time.
