Unplayable 1.17

When I play the new version 1.17 it is not possible. In the meantime, at 1.16.5 I have excellent performance. Despite the positive fps on page F3, when walking (especially outside) it feels like 2 fps. I tried to change the projection distance, video parameters, but it helps. If I set the values less, the lags do not get less. If I increase the values, the lags do not increase, I think it's not about the video settings for sure.
