I decided to see if the same problem happened on my gaming laptop. (See DXdiag.txt attached) The same thing happened. Input lag every few minutes for a couple of seconds. Mind you, I have never installed BF 2042 on my gaming laptop, I don't play FPS games on it, so it was a fresh install.
So, I use GeForce Experience on both my desktop and laptop. On my laptop, there is a setting for "whisper mode" under the settings. I set it to whisper mode and what it thought were the optimal settings for my laptop. Mostly things on high, some ultra, and a few mediums. In the game, my CPU usage was down to about 60% and the game ran smoothly at 40 FPS. I then translated those settings to my desktop by moving the PROFSAVE and PROFSAVE_profile files to my desktop. No luck, CPU usage is still at 95+%. But maybe it has something to do with power settings for the CPU and GPU?
