Fixing Converter Lag / Increasing the USB Rate

[Dreamcube017]

You oknw... when it comes down to it... I think it has something to do with your mother board too... because with this new computer... there's no lag at all... it's like the PS2 one.... Amazing.

Polling rate doesn't do much but I don't really need it.

I was sniffing around, and looking for changing Vista polling rates and this is what i found it...here

it says at your own risk, but if you're still having tons of problems.. this should work.


EDIT:
also found that hidusb.sys works quite well with vista. I prefer this solution much better as it has a lot less fiddling with your system, and this is much more simple. click, install volia.

Polling rate does a ton, and yes you do need it, and your motherboard has nothing to do with the frequency of your USB ports.

I've got Windows Vista, and a IIDX JPKOC. I don't have an option for a Serial Port.

What USB adapter should I get?

i have a superjoy box 3 pro and it works really well for IIDX and stepmania

This lag that we're talking about... is it when you press the keys fast, and not all of them register? I just want to clear it up.

I just bought a converter. It works fine with the PS2 dual shock controller, like all of the hits register even if I mash the buttons fast. But on the JPKOC, not all of the hits register.

I've tried increasing the polling rate by 250Hz, 500Hz and 1000Hz using UsbRate v0.5, and nothing happens.

The lag is when it takes longer than it should to register a single key press, resulting in key presses being late if you don't adjust.

yeah, but pressing buttons at a slow rate doesn't make it lag. It only does if you press fast.

Example: I press a button 5 times within a second, and only the first and last hits register.

And yeah BTW, I had no idea you had to reset after setting the poll rate. I fixed the damned lag. kay, thanks anyway. Why does this happen to me lol. I figure out shit right after posting.

input lag used to drive me crazy 'till i found this app

http://cpsc.ucalgary.ca/~cheguo/File...tLagTestor.zip

it allows you to get an accurate reading of just how much input lag you're experiencing from any given input in milliseconds

if you're testing out your ps2-usb adapters, you might want to use joy2key or something

using this, i've found that my dilong ps2 to usb adapter adds very little lag whatsoever, neither does my usb refresh rate or lcd monitor

no matter whether i'm using a crt or lcd, a wired or wirelss keyboard, a usb joypad or ps2-usb adapter, i always get around 16.5ms of input lag

when i test this on my other two computers, i get between .5-3ms input lag

i've finally detemined that the extra 15ms or so is due to the nvidia drivers

i'm using an nvidia 9800gt, and from what i've gathered by asking others to test their input lag and report their results, is that nvidia just add's an unavoidable 16ms of input lag when you use their vidoe cards/drivers

it's quite a shame really

radeon's seem to only have about 4ms input lag

now 16ms might not seem that much, but it makes all the difference in the world when it comes to beatmania and ddr games in pc

stepmania has the 'global offset' feature, which allows you to enter the value of -16.5ms into the config file, which makes it pretty much dead-on

unfortunately i haven't found any way to make input lag adjustments for any iidx games on pc so far.

please give the app a try, and post you input lag and video card settings, just so i might be able to confirm some theories.

ummm..both BePachi and LR2 have timing adjust options. In BPM, it's outside the actual game (well, technically, it can be accessed through the main game, but it's easier just to load the options program first), and LR2 has one in game under play settings.
