Asus ROG Harpe Aim Lab Edition with polling rates higher than 1000hz (4000 or 8000hz) isn't officially detected in G Helper, and you can crash the program by choosing the blank option presented in the polling rate drop down box

What's wrong?

The Asus ROG Harpe Aim Lab Edition mouse was released with a max polling rate of 1000hz, which G Helper supports fully. Some time after its release, Asus released a polling rate booster that works with the wireless dongle as a USB extender, and this enabled 4k and 8k polling rates. If you try to alter the polling rate in G Helper, it cannot see those new rates, and the drop down menu for polling rate is blank; if you then click that menu and choose the blank option, the program crashes. This is a bug report for the crash, and a feature request to support those higher polling rates.

The polling rate booster is purchased separately. Here is one vendor: https://us.maxgaming.com/us/other-accessories/rog-polling-rate-booster

The process to enable these higher polling rates requires several steps, described in this Reddit comment and throughout the thread: https://old.reddit.com/r/ASUSROG/comments/1g1e9gp/help_i_bought_the_rog_polling_rate_booster_for_my/lrk5mm8/

How to reproduce the bug?

1. Set up the polling rate booster and install Armoury Crate along with required firmware updates for all hardware
2. Adjust the polling rate in Armoury Crate itself to 4000hz or 8000hz. At this point the official software is no longer required
3. Open G Helper and choose the mouse under peripherals (ROG Harpe Aim Lab Edition (OMNI)) to open extra settings
4. The polling rate drop down will be blank. Left click this, and left click again to "set" it to that default value.
5. G Helper will throw an exception with the text "Index was outside the bounds of the array", and you can continue or quit at this point. There's also a details option that shows error logs, and that text is pasted below after the log.txt upload.

@Crysalim hello,

Try this build, I have added options for 2k, 4k and 8k HZ.

GHelper.zip

[Crysalim]

@seerge Excellent! I just tested this build some and the new rates, at the very least 8k, work. I'll be using this build from now on. I temporarily reinstalled Armoury Crate to try some things too, here's some of what I did:

• With just G Helper open, the new polling rates all seem to work. I can't tell for sure with 2k and 4k (the differences in mouse movement are too subtle for me to know for sure), but going from 1k to 8k and vice versa and then choosing "synchronize with mouse" definitely works.

• Changing polling rate in Armoury Crate always alters it - normal behavior from before - then choosing "synchronize with mouse" will show that rate in G Helper. Alerting the polling rate in G Helper first, then opening AC, doesn't change the displayed polling rate there, though (maybe because it doesn't actually check and assumes the last value in AC is still correct?)

Since Armory Crate doesn't seem to care about G Helper changing the rate, I can't know for sure if 2k and 4k work, but since the difference in mouse movement is obvious enough between 1k > 8k, I think they do. If there's any other testing I can do to help let me know since I have the hardware.

[seerge]

@Crysalim great.

AC never reads settings from the mouse itself, but rather shows last settings applied by AC itself. So it's all correct.

Does AC offer 2k and 4k options as well? or only 8k ?

[Crysalim]

@seerge It does, yes. Here's a screenshot of how it looks for reference.

[seerge]

@Crysalim ok, and does setting 2k and 4k in AC reflect in G-Helper afterwards ? If so - everything is good

[Crysalim]

@seerge Yep it does, you just have to activate synchronize with mouse, and it'll update the drop down in G Helper even without reopening the program. Ty for the promptness on this, too!

[seerge]

@Crysalim ok, then it works as it should. Thanks
