SER 8 - Gaming freeze - USB and bluetooth problems

Wollemi

Dear Beelink Support Team,
Dear Users

I purchased a Beelink SER8 approximately 1.5 years ago. Until now, I have not used it for gaming, but this week I started testing more demanding games and encountered a serious issue.

When I load a save game in The Witcher 3 and the actual 3D gameplay begins, my wireless keyboard (connected through a USB receiver) immediately starts lagging. The mouse connected to the same receiver continues to work normally, but the keyboard input becomes extremely delayed, sometimes by several seconds or even minutes.

I also tested an Xbox controller connected via Bluetooth. As soon as a demanding 3D scene is loaded, the controller disconnects and can no longer be used. I experience the same behavior in God of War.

Interestingly, game menus work normally. The problem only appears after entering actual gameplay or a demanding 3D scene.

According to AMD Adrenalin, the integrated Radeon 780M GPU reaches only about 70% utilization and does not appear to be fully loaded.

To troubleshoot the issue, I have already performed the following steps:

Performed a completely clean installation of Windows 11 from a USB installation media.
Updated the BIOS to the latest version recommended on the Beelink forum.
Installed the latest AMD chipset drivers.
Installed the latest AMD graphics drivers (Adrenalin).
Updated the Intel AX200 Wi-Fi and Bluetooth drivers.
Disabled USB power-saving options for all USB Root Hubs.
Disabled Steam Overlay.
Tested both Bluetooth and USB receiver-based input devices.
Verified that the SSD is healthy and operating normally.

After reinstalling Windows, Chrome, Steam, and the operating system itself are stable. The games no longer crash, but the input device issue remains unchanged.

Less demanding games such as Vampire Survivors and older 3D titles (for example, Psychonauts) run without any problems. The issue only occurs in more demanding games.

Because the problem persists even after a clean Windows installation, BIOS update, and driver updates, I am concerned that there may be a hardware issue related to the motherboard, USB controller, Bluetooth module, or another component.

Could you please advise on any additional diagnostic steps or known issues related to the SER8 that could cause this behavior?

Thank you very much for your assistance.

Kind regards,
Wollemi

Hello there,

Could you please send us a picture of SN code(two lines) at the bottom of machine ?

Could you please take a picture of the BIOS main screen of your machine for us to see?

You can try to clear CMOS : Please turn off the PC , unplug the power supply and HDMI cable , and press the CMOS pinhole for about 10 seconds. Ten minutes later, plug the power supply and HDMI cable, turn on the PC again.
Please wait about one or two minute, if you can go to the system.
Please repeatedly press delete key as soon as your restart the PC, go to BIOS. Go to Boot option, enable fast boot, press F4 to save.

Have a nice day~

Dear Beelink CS-June,
I performed the CMOS reset and overall performance has improved. I discovered that my TV was configured to 30 Hz instead of 60 Hz, which limited performance. After correcting this setting, the iGPU now performs as expected.
However, the Bluetooth/input issue still persists.
After the CMOS reset, the Bluetooth devices disappeared and had to be paired again. I also identified an issue with my Dell wireless keyboard and mouse combo. The mouse works correctly, but the keyboard develops severe input lag (2–3 seconds) and eventually stops responding during gameplay.

The Xbox controller now stays connected in The Witcher 3, but input lag is around 1–2 seconds, making the game unplayable. The same behavior occurs in Diablo IV.
In God of War, the controller disconnects immediately after gameplay starts.
Even in Vampire Survivors, controller input lag is approximately 0.5 seconds, which significantly impacts gameplay.

I tested a simple wired USB keyboard, which works perfectly. However, my intended use case is gaming with wireless Bluetooth peripherals, so using wired devices is not a practical solution.

The situation is much better than before, but Bluetooth lag and disconnections still occur under higher system load.

I have taken photos of the serial number and BIOS version. How can I send them to you?

Kind regards,
Wollemi
