Found the fix from subsidence FPS (Kingdom Come: Deliverance)

Probably many, as I rode the FPS in the game. Digging at English-speaking forums and various websites proved that this problem is RAM. Below the Board to fix this problem.

1. Right-click your mouse on Kingdom Come: Deliverance in your Steam library.

2. Select the Set launch options, then copy/paste heapsize your RAM:

4GB: -heapsize 524288
8GB: -heapsize 1048576
12GB: -heapsize 1572864
16GB: -heapsize 2097152
24ГБ: -heapsize 3145728
32GB: -heapsize 4194304
64GB: -heapsize 8388608

It will not give an increase to FPS, but will improve stability. For me personally it worked. I have to say that these prosdocimi completely disappear, but will become less frequent and less prolonged. Hope will help you) enjoy the game)
