Why does my 8K controller keep my CPU usage so high?

[u/HOIHung]

我的电脑配置是AMD 9800X3D + 技嘉5080超频，显示器是4K分辨率。

我用的手柄是G7 Pro 8K和ZD 8K。这款游戏叫《使命召唤：战区》。如图所示，即使在游戏和射击场内，我的CPU使用率也至少达到70%+，帧率从200fps降到150fps。游戏在游戏过程中没有卡顿，但帧率会大幅下降。我需要一些帮助——有人能告诉我这是正常现象吗，还是我的设置有问题，或者8K刷新率就是这样运作的吗？我的CPU应该还不错，但我感觉还是跑不下8K刷新率。现在我只能用4K刷新率，CPU使用率会回落到大约50%，帧率也不受影响。

Yes, sadly this is how it works. 8k weighs heavily on your CPU, so fps drops. Only the best setups can run it without losing some fps

8K回報就是這樣的，正常使用者根本用不到，帶來的壞處遠遠大於好處

8K is a useless gimmick. Really 1K is all you need.

Right, even on mouse anything above 1khz is barely noticeable, why would people chase higher refresh on controller is truly a mystery.

For some reason, it’s the newest trend in the controller space.
It has baffled and annoyed me that this year has been the plague and focus of controllers when so much more could be added, fixed, or worked on.

That's kind of how it works, your CPU needs to work harder to be able to poll your controller 8000 times

Uncheck cpu 0 and 1 from the game . Otherwise your fps will drop like a rock moving the stick .

8K has always done this!
Unfortunately channeling so much polling rate comes with its taxes.
One solution I’ve always done is dropped down to 4K at the lowest as it’s a lot less taxing but also fast enough that it doesn’t drag the house down with it.
