Intous Pro 2017 (PTH-660) Bluetooth lag

Hi,

A month or so I got the latest Intous Pro M, I was quiet underwhelmed by the bluetooth performance, essentially the cursor was noticeably sluggish, on Win10 it felt like the cursor operates at max 50fps ( that's what my 3d app viewport was reporting ), and in Mac OS (tested on 2 different mac laptops) it was noticeably lagging behind although smoothly. Using USB connection everything is buttery smooth.

Today I've received a new Intous Pro M unit after Wacom exchanged the faulty (?) one, but the problem is still there! So I was wondering if anyone else is having the same issue with the latest Intous? is that how it actually performs? Do you guys notice any difference in cursor performance switching between USB and BT?

Cheers!

Bluetooth wireless connection can be influenced by other wireless signals and is a bit slower connection than direct cable connections. But normally you should not notice a very big difference after the first few seconds of connection. - Make sure that you have the latest tablet firmware installed and the latest tablet driver. Then use Wacom Desktop Center Backup Settings -> Reset settings and test. If it is still lagging, try to turn off other BT connections and wireless connectins. Wifi on 2.4 GHz and USB 3 cables can send interference on the same frequency as well. So disable such things to see, if they affect the Bluetooth connection speed. If so, measures like switching Wifi to 5Ghz or a different WiFi channel, using other USB ports or better shielded USB3 cables should help.

I've tried the tablet in 2 different corners of the world, on 3 different machines, both inside and in a field where there's no interference whatsoever, it behaved exactly the same. This time I deliberately tried the tabled with older firmware and upgraded after that, performance is exactly the same, reseting through Wacom Desktop Center did not help, hard reseting through the little pin hole on the tablet did not help either. I feel like I jumped on a batch of tablets with failed BT hardware.

In case you are using a Mac, you can check signal strength with these steps:
a) Pair the Wacom Intuos Pro tablet to the computer.
b) Hold the Option key while clicking the Bluetooth menu to get additional information and settings for Bluetooth devices.
c) With the optional Bluetooth menu activated, select your listed Bluetooth device and the submenu for it should show the detected RSSI value for it.

RSSI = Resource Strength Signal Indicator, RSSI should be between 0 and -50. The higher the value the better performance.

There is no similar option included with Windows, but there is probably some freeware tool for Windows, that can do similar checks.

Hi
Similar problem here. It seems like it happens after some time. At first everything is fine, then after an hour or two it starts lagging. Same tablet bought about two months ago.

If it starts lagging after some time, restart the computer. If that helps, the problem is on the side of the software. Otherwise could be hardware side.

Mac os 10.12.6, wacom driver updated to 6.3.25-2, wifi off, bluetooth rssi from -49 to -42 dBm - noticeable lag. With usb cable works fine. Any solution? And one more thing: does the corner marks suppose to be lit? Now just touch ring led is on.

What we have seen is an issue within the Bluetooth specification: Bluetooth always checks all known devices (connected or not) if they have some information to transmit. This conflicts with the high data rate that the Intuos sends.
Typically you can enhance the behavior by removing all not needed Bluetooth devices from the computer.
And, it helps to not use other Bluetooth devices while working (like a headset).

On some computers you will as well see a higher CPU usage when using Bluetooth.

No chance not having bluetooth (BT) devices near the computer, as long as your machine is iMac 27" 2017 (BT keyboard and BT mouse). Ok, Intous works fine with the usb cable attached. How to turn it off? Power button with the cable attached doesnt work. And what about those corner marks, do they have to be illuminated?

Dear Wacom, please answer these questions about pth-660:

1) tablet conflicts with iMac BT keyboard and mouse and it cause cursor lag, so have to use it with usb cable attached. How to turn tablet off when not in use?
2) do corner marks have to be illuminated when device is on?

Thank you!
