[2021] WTF is going on with FPS? Huge FPS loss after weeks of great performance.

I recently upgraded my PC for the last time for PUBG. In the first days-weeks everything was butter smooth. I was FINALLY so happy with the performance. Stable +140 FPS most of the time.

i5 11600k

rtx 2060s

16gb@3300mhz

I didn't limit my FPS, so it was around 170-150, I had ocasionally dips down to 120 fps, but only in ranked with a lot of smokes etc.

Now after few weeks, and after 11.2 I have again the FPS that I had on my old PC. It dips HEAVY to 110-120FPS in "normal" situations, with no fights or players around.

WTF?

I noticed that my GPU usage is now at times 50-60%, whereas weeks before it was 85-95% all the time.

Shouldn't it be at max most of the time? Why PUBG choses to use 50% of my GPU in open areas, and 95% in a closed bathroom?

Tried to change nvidia drivers, but nothing helped. Older or newer, doesn't matter.
