Opus is using a lost of CPU and found that apparently opus7zip.dll is the culprit.
It's normal for CPU to be used when unpacking RAR archives, which is what the "UnRarServer" part indicates.
Is that what you are doing, or is something else triggering it?
Which version of Opus are you seeing this with?
Do you see issues opening or extracting the same archive(s) when using WinRAR?
If there is high CPU usage from just opening or listing archives, it could mean an antivirus scanner is involved. (Depending on how the RAR archives are made, it could also be normal, as some require a lot of disk and CPU use just to get a directory listing out of them.)
I was decompresing some files, but the cpu usage keept at 100%.
I´m using 11.17.
I only use opus to handle compresed files, so I might have to test other programs. The decompresion works fine, is just that after the fact the CPU usage keeps high.
I have a compresed NTFS partition on my HDD, so that might be an issue?
I have an intel i5 @ 4.4 GHz.
