Title: SFML is bucking
Post by: BorisDieKlinge on February 10, 2009, 11:22:39 pm

Hi there
I've got a problem with SFML I already wrote about in the German forum. Now I've been told by Tank to tell you guys about my problem. Here we go...

My System:
Windows-XP-32-Professional
HD4850
Q6700
3GB Memory

SFML is not running smoothly on my computer. When I launch the pre-compiled examples provided with SFML (like opengl.exe), they do run with an effective FPS of 75. But approx. every second my mouse cursor judders, aswell as the graphics in the SFML application (like the cube in the opengl.exe example).

Compiler issues aren't an option, since I'm using the pre-compiled binaries. I've already got the latest video driver (Catalyst) for my graphics card. I also tested OpenGL with CS 1.6 (OpenGL mode) and several NeHe examples from http://nehe.gamedev.net/.

I hope this description is detailed enough to give you an idea of my problem. If you're speaking German, you could also check out the original discussion at the German forums.

Sry I used this: http://dict.leo.org/ende?lp=ende&lang=de&searchLoc=1&cmpType=relaxed&sectHdr=on&spellToler=on&chinese=both&pinyin=diacritic&search=ruckeln&relink=on

I don't know the word for 'it doesn't run fluently. It freezes for a very short time during running.'

Maybe the word is lag or lack?

To make sudden jerky movements; jolt: The motor bucked and lurched before it finally ran smoothly.

The best def. I founded.

Come on guys, not everybody here is a native English speaker. I'd suggest to help out the thread starter instead of making fun of other people.

Omg, how tragic is this? :roll:

I make a lot of mistakes myself, I normally don't comment other's mistakes, but this one seemed to me a little bit funny because the sentence got a new meaning. I didn't want to blame Daazku or anything like this. No reason to begin a discussion about native speakers...

Windows XP 32-bit can be unstable when it has more than 1 GiB of RAM.  Try taking some RAM out and try again.  Otherwise switch to a 64-bit operating system.

What leads you to this conclusion? Officially 32-bit Windows XP supports up to 4 gibibytes of RAM. (although some of it is inaccessible due to other memory mapped on top of it (like VRAM))

The phenomenon you describe reminds me of a strange bug I once experienced when running Quake3: The game ran smooth, but every few seconds, it just "froze" for a short period of time.
The reason for this  was that I had unplugged my GamePad, but Windows thought for some reason that it was still there. So I guess Windows tried to "poll" the GamePad in regular time intervals, which caused the stuttering. After I removed the GamePad in the Control Panel, the problem was gone.

However, as you wrote in the German forum that you also tried examples that do not use any SFML-input stuff, this explanation might be unlikely. But as you don't have problems with the NeHe-examples (which are graphics only), I think this problem might be caused by some SFML-code that is not graphic-related.

Have you tried to strip down an example where the problem occurs? If you have some sample code, try to remove all Event-Handling and Input-Related code and try again.
You could, for example, remove the event-processing in Wolfram's sample code (you won't be able to close the application if you do that, but as it's only thought for testing, that might be ok ;) ).
