Hi I have a problem with 100% disk usage while playing a game. I only play Black Desert and Statecraft 2 in my pc and every time I opened this game, the "system" in the task manager goes up and causing constant 100% Disk. I usually turn on one game in windows mode and let it run for like 8~ 12 hours every day. I did not experience any unexpected shut down of games & pc nor slow performance of computer & exceptionally high temperature of ssd, cpu, GPU due to this high disk usage but I am worrying that this would affect in a long term. I also checked that the "system" is causing about 35% to 50% usage even I watch hd video from youtube ( I do not experience this problem when I just use internet or Microsoft office). I believe I do not have this high disk usage problem during games before few weeks ago. I am kind of suspecting recent windows 10 update causing this problem but to be honest I have no idea why and how this problem happen.
Please help me to solve this high disk usage problem.
cpu: E3 1241v3
