irrlicht based games really fast on my pc....

Hello a few games from the list here:
http://www.irrlicht3d.org/wiki/index.ph ... weredGames

irrlamb, people shooter, witch, PacAnd, and warboard 3D

It seems all of them do not run right, most of them seem to run really fast, like i'm using a speed hack on the programs...

The examples in the irrlicht seems to run right, has anyone else had this problem and know how to fix it??

I am guessing a bit here but I have seen a number of reports of vsync not working very well on some systems, perhaps they are fixing they frame rate with vsync alone and if this fails they end up running at full frame rate?

they didn't use time-based movement (frame rate dependence instead) so when your computer is better than theirs (and runs on higher fps) the whole game will become like speed-hacked.

...and will "run" like a turtle on a hot summer day if you have a crappy computer.

well that just seems retarded.... so the only way to play theese games would be to get a pc like the person who made it?

Or to ask the author to write their code correctly and provide a fixed executable.

it's not irrlicht's problem.

You could try a program like CPUKiller. I've never used it before, but it could work.

maybe they use an old version where the timing had problems with dualcores?

6 games with the same problem? that seems a bit odd.... ill try the cpukiller and see if that works

--edit--
I just tried it, it does kill your cpu but it doesnt help with the games there just as bad, even worse cause now you get lag...

Yep probably. Set affinity in task manager to use only one core

I didn't think to do that, it works, now the games run fine after i do this.

Thanks for the help everyone!

Hey guys, who do you think I am? Of course I´m not using frame speed, that would be insane nowadays. I use proper timers. I can´t recall now, and have not code at hand, but I´m probably using QueryPerformanceCounter. I remember it has some problems under certain processors, or probably 64bits architectures, or any other thing.

I´m talking about Warboard3D.
It may run at different fps render rates, but the logic will run at proper time slices.

So, could you please darthneo post a video about the issue, and let us know about your processor, operating system, and stuff?

Thanks.

PS: I bet the other games are using proper timers, but I don´t know.

<edit>

Err, actually I should have read all the post before posting. Hehe. It seems they already pointed you in the right direction, which is a problem in the timer with multiple cores.

Googling multiple core queryperformancecounter:

(there were many others better than this, it´s just an example of the problem).

If you have an AMD dual core there is a bug in the AMD side of things, that makes it fast. Set the affinity to one processor in the process (taskmanager) or install the AMD CPU drivers from your motherboard.

It happens as well with other dual cores but the amd was the problem here.

Do anyone even bother to read replies anymore?
