Brian.

Exi386InterlockedExchangeUlong would probably be called by
InterlockedInterchange(). I don't know if it is your code or other code (
STL uses it ) but since that basically locks other threads it could be what
is causing it ?

P.S. It might also be called from InterlockedIncrement() and
InterlockedDecrement() ?

[GD-Windows] Keyboard lag

[Pierre T. <p.t...@wa...>]

RE: [GD-Windows] Profiling anomaliesHi everyone,

When I keep a key pressed (e.g. pressing say "z" and keeping it down) my =
app starts "stuttering", as if there was a big lag in certain frames. It =
doesn't seem to always happen, and I'm not doing any special =
keyboard-related stuff, AFAIK.

Any idea what the problem is and how I could fix it ?

Thanks.

I'm seeing the same (using WM_* for keyboard input).

You might want to try to disable the TranslateMessage call in your message
loop (in case it exists), which seems to cause problems similiar to those
you describe.

Eh ?!
I have a TranslateMessage indeed. Well, I had. I currently don't see the lag
anymore so maybe that was it (until it shows up again). In any case, thanks.

This gives birth to a new question anyway : is there a standard "best"
message loop for typical cases such as games or realtime 3D applications ?
Or : are there other things like that I should know ... ? It seems pretty
important to know TranslateMessage could yield problems, yet that's the
first time I read about it. (I'm admittedly not the Windows expert)
