Apparently every system so far seems to work at 0.05, I'd say hardcode it to that value. This would be even faster than the current minimum sound lag we have (0.1s), so there should be no complaints. I'm glad to see that you have finally found a solution

Just for reference, I'm on XP with an Audigy 2 ZS and have no problems even at 0.01s.

Vista rc2 5744 , nothing running except OS stuff + IE.

0.03 is lowest flawless i could get. 0.02 has a skip every 5 secs or so. 0.01 is skipfest.

cmi 8738 c3dx onboard.

amd@1.71 on asusV333deluxe.

ok im gonna try it with vista 32bit build 5600 and with a 3700+ cpu onboard sound and a 16mb graphics card. im unsure if the graphics card makes and difference but bear in mind my graphics is all being done by my cpu. "ill be back"

0.03 is good for me.

Vista RC2 build 5744 x86
Default nForce2 drivers (6.14.462.0 = 4.62)

0.02 sec = very few scratches
0.03 sec = perfect

Vista RC2
latest x-fi vista drivers

0.01 i get pops.
works fine from 0.02 and higher.

also all frequencies seems to work fine

win xp 0.02

but the program doent work .

he say:

Sound Test: DIRECTSOUND

start/stop(s): Stopped

i allso have sound problems ,
scawen i hope u can do some think with this information

Vista RC1 : 5600

0.02 is fine, 0.01 is mostly fine but not 100% perfect all the time.

Using Realtek 882 HDA chip on ICH7R of Intel 975x chipset (asus p5w-dh)

That's what it says when you first run the test program.

You must press S to start the sound. Does it work then?

TEST Patch U23. DirectSound now implemented into LFS!
