Game Freezes every 3 seconds for 1 sec

This thing is from launch of the game, i hoped that u would fix it but i think you don’t even know about this problem. Every 3 seconds my game freezes for like 1 sec. Fps goes from 75 to 20 and like that. Many players have this problem with decent PC. Try to fix this please.

not the perfect solution but im pretty sure it will work for now if u turn off all chats
