1  Game Development / Performance Tuning / Re: An efficient discrete step timing loop. on: 2003-10-08 20:48:48
In Markus_Persson's original code, there was a timer.getTimeInMillis().  I accidentally used the AdvancedTimer's getClockTicks(), which is NOT in milliseconds.  Things behave as expected, no more sleeping either, when I slipped in System.currentTimeMillis() temporarily.
I need to do some math in order to correctly use the AdvancedTimer.  Thanks.

2. Download GAGETimer and turn off the CPU monitor.
I've come upon the same realization recently.
Could you please explain the bit about turning off the CPU monitor?  How much would it really help and what's the worst that could happen by doing so?  Thanks.

Well, I got rid of the flicker by adding a timer.sleep(22000).
I'm using the GAGE AdvancedTimer.
I now get 66 fps while @ 1024x768, 85Hz.

I'm assuming that I don't see the flicker anymore because the 85Hz sufficiently covers the 66fps and the beat frequency becomes unnoticeable.  (yes/no/sorta?)

Still feel like I'm at the mercy of some mysterious forces.
BTW: WinXP home edition, 1.8GHz, NVidia TNT2 Model 64- 32Mb.

Hi,

First post.  Learned a heck of a lot from you guys- thanks.

Question- while testing this game loop, I notice that my fps seem to be limited to the refresh rate of the screen mode I switch into.  Is this a Window's "feature"?

Edit: Hmm- I just found an answer: http://www.xp-refresh.net/

Also- I understand what vertical synch is all about, but I don't yet see how to "do it" with pure Java.  (I do see how to do it via LWJGL- very nice btw).  I currently get big time flashing- which is what I'd expect if my buffer.show() isn't synched with monitor's vsynch and their respective rates aren't perfectly in synch.  But I'm a big time newb- maybe I'm missing something.

Could someone give me some pointers, advice, links?
Thanks a lot!
