Debunking Gaming Latency Myths on Ryzen 7800X3D/9800X3D, Windows 11,RTX4090/5090

I tried disabling usb power saving via device manager and setting the PC to maximum performance. I also tried 5400 RAM without anything and with 6400 Expo but it doesn't seem to make any difference. I updated to the latest BIOS if I set the mice to low dpi like 700 800, always with precision enhancement disabled, they seem to go at 3000 dpi very fast and then as I repeated even when dragging files and folders it seems that I lose the input and I have to do them again, same thing with the clicks and then the movement freezes as shown in the YouTube videos.

Well based on what you’re describing now its unlikely EMI/electricity.

“Maximum performance” power plan can actually make your issue worse. I'd recommend going back to "Balanced" for troubleshooting.

So the fact multiple wired mice behaved the same, low DPI still feels extremely fast, clicks/drag and drop intermittently fail suggests Windows is not consistenytly processing HID input. I don't think anything is misconfigured on your mice. DPI does not randomly rescale itself. When it feels like “700 DPI behaving like 3000” that’s almost always event loss or timing collapse and not sensitivity.

Honestly all what you've said so far points to a USB/firmware/driver level issue. Youre on a new chipset (B850), new GPU gen (5070ti) and I assume W11 25H2. This kind of behavior is consistent with USB controller firmware bugs, chipset driver issues, DPC/ISR starvation or a device driver misbehaving at kernel level.

What I would try is what I suggested above, switch your power mode back to "Balanced". Install the latest AMD chipset drivers directly from AMD (not from your motherboard's website). Temporarily disable WiFi and Bluetooth in both your BIOS and Windows. Test ONLY keyboard and mouse connected. Run LatencyMon while reproducing the issue and check if any driver spikes when input freezes. If LatencyMon shows large spikes from network drivers or USB controllers or ACPI or GPU driver that will immediately explain what’s happening.

What you’re describing is not normal and not expected on X3D. Its not something people should “tune around.” Yours is a system level problem that needs to be identified and fixed. Once you fix it the mouse feel and responsiveness should snap back to normal instantly.

I understand, I hope the problem is due to what you think it could be. Later I will do these tests and publish them here in the meantime, maybe if I can also write to you privately on a discord, if it is not a problem otherwise here too it is fine for me. Thank you for giving me hope. One thing I did not say in the previous post is that I had a PC before the current one that had a Ryzen 7800x3d 4080super Asus B650 Plus WiFi. The first week the mouse, tracking and everything worked perfectly. After that I don't know what was the cause, I had the same problems mentioned in this PC. I sold it and bought this one in which the problems were there from the first start-up with only the mouse and keyboard connected.
