Keyboard Lag Debugging

[Nekki]

Not sure is this data found by me can help. Doing some test about poll rate of my touchpad, it gave me a 80Hz rate constant in either recent reboot (not touchpad problem) and when the touchpad start jumping by itself. On both cases I have 80 Hz of poll rate. The difference in problem-state was the software used lost the strokes as my touchpad did. I mean, when I lost the touchpad control, I can not register the touchpad poll. When recover, it return to 80 hz. As comnparison, the USB mouse has 120 hz rate.

Comparing this number, this number are similar to alienware m17, which by bios update (because of bad touchpad performance) the increased the poll from 20 Hz to 80 hz.

FIX THIS GODAMMIT!

...sorry.. sorry... need to breathe in. No, really, can't believe a device as elemental as the keyboard just won't work with the G73JH. I'm currently flying without the Synaptics drivers and using Touchfreeze which does not work on remote desktop sessions or logmein sessions, plus it is not very good when you try to type fast.

So next time I'll try to uninstall ATK and install Synaptics and see how I go without.. no forget it, I use ATK keys a lot.

Grr.. I had hoped they would fix keyboard lag before GSOD. Really, I game on this thing but that's like 10% of the time I use it at best.

How do you access the polling rate for the touchpad?

OK. I've been working the crap out of this issue. We are not correct about the ATK package alleviating the problem. My keyboard still misses keystrokes and gets laggy with the ATK package removed completely. The ONLY thing that eliminates it on my system is running with the stock MS driver or disabling the pointing device in BIOS.

I searched through the registry carefully looking for anything we could tweak. I was hoping to find a polling parameter. There are none that I can find. Everything I found in the registry is available in the touchpad settings interface.

At this point its looking like I'm still at the mercy of Asus to find the bug and eliminate it. I guess they need to modify the polling rate in BIOS or get Synaptics to modify the driver or something. I wish we could get our hands on a completely unlocked BIOS. There are a lot of things in there that can be tweaked. The BIOS we have can't be tweaked at all. Everything is hidden.

I agree that these drivers work on dozens of laptops and exhibit zero problems on hundreds of thousands of laptops. There must be something specific about this laptop that needs to be corrected. Asus might be able to work around it with a custom driver but something in the BIOS or hardware is probably the root cause.

Did you look in Device Manager and check the resources used for "Keyboard Device Filter"?

[HeavenCry]

What if it is the hardware (JH touchpad) + driver (Synaptics) combination that is problematic here?
Im wondering if the JW upper panel (the panel that holds the touchpad and all the buttons is similar enough to be used on the JH? If that worked we could just order the JW panel and use that (and even get a better touchpad)...
I know its a long shot but can you check this Quadzilla (or anyone else that has both the JH and JW)... Pretty please ?

[HeavenCry]

Gary could also answer this if he looked into it...
Im sure that some people would be interested in doing this just for the touchpad if nothing else...
Hes here now so would you ask him for us Chastity?

[Chastity]

I fixed my lag issue by updating the Asus drivers, like the ATK Package (1.0005 at the time)

[HeavenCry]

No matter which ATK or Synaptics driver i use its pretty much the same (some are marginally better than others, but none completely solve the problem).

I thought this was resolved if you disabled the trackpad in the bios and used an external mouse.

Wouldn't that be an acceptable solution for heavy typists?

Since I always use external Keyboard and mouse I don't have this issue but since we know there is a problem for many people and they has been no consistent resolution of the problem, it seems carrying a small BT or USB mouse around is a small price to pay to alleviate such frustration.
