High CPU render load after 20 Min

Hi there!

I tried to play the game and installed it via the XboxApp. I want to play with friends, so i only tried it on multiplayer and a server rented from nitrado by a friend.

For the first 20 Min there is no problem, CPU render load is at 30-50%. After 20 Min it spikes up to 180% and back to 60%. This causes the simulation speed to go down to 0.50-0.60 and giving me "lag" every 4 seconds. The problem occurs even on a new map (on Earth, Pertam and in space), with no mods and minimal blocks (20 Min playing).

I tried:

every GPU settings (Low/Med/High/Mixed)

V-Sync on/off

deleting the Shaderfolder

reinstalling the game

reparing the files via the xbox App

changing the server render distance

Nothing changed and after 20 Min the problem accured again again and again.

My specs: AMD Ryzen 7 9800x3D, AMD Radeon RX7900 XTX, 2x Corsair vengeance 32 GB DDR 5 RAM, Samsung Odyssey G9 Oled 5120x1440

and the game is installed on a 4tb Samsung SSD (C drive) which is attached direct on the motherboard.

Attached you find the latest log file. Can you please tell me what am I missing or what i could change to play the game without problems?
