After playing some amount of time game is starting to freeze, rendering distance is changing on its own, animations freeze. I recorded it and link is below, sorry polish chatter in background. FLUSH didn't work before so i didn't tried it today. Its my first bug report here so, if something is missing ask straight away.
CPU and GPU usage was ~25-30%, RAM ~12gb and VRAM 8GB.
*VD- View Distance
20:25 i joined server
20:30 loaded on map
22:30 first signs of something wrong, VD is slightly changing at max distance.
22:35 in those 5 minutes VD went from max (2km) to 50-100m, game freezed a lot, at the end animations also freezed, became unplayable, i had to restart game. Those 5 mins are in video below, i tried to push it more, usually i restart game when VD starts to change drastically.
22:40 i went back on server and map, game works fine
00:15 few freezes
00:25 VD, freezes same as 22:34
00:30 back on server, works fine
01:40 VD jumps again, ~1min between slightly and unplayable (as a pilot)
01:45 i am back on server and it works fine again
It also happend to my friend in similar time-frame but after 3rd time he set up sys memory to 10240 and it didn't happend again (it might be because we didn't play long enough, needs more testing). He also told me that when it happens game takes 1-8GB of RAM and then its switching between 8-10gb usage every second.
Video, i didn't cut it except censoring some alt tabing so its raw
