Hohe RAM Auslastung obwohl kein Programm läuft?

There are always programs, dozens, you just don’t see them.
The operating system alone brings some, then there are also programs from you that run in the background.

If there’s 30% evidence, check what this is, either with the TaskManager or the ProcessExplorer, which gives you some more data.

However, it can also be that you do not have a single process so much RAM, but rather a little bit, which then sums up. This would mean that you have either installed a lot of garbage and running in the background, or installed too little RAM. Since you have installed 32GB (and I assume that they are also recognized correctly), the latter will naturally fall away, so still that you have installed garbage 😉

So see what you have installed, especially in the car start and throw out some of these programs. Or reinstall Windows, that can be a good idea at times, especially if you install a lot on the PC back and forth (de) and, if necessary, do not take care of what this is and whether that is reasonable.

What “Controls the DTS Audio Processing object” is, however, I cannot tell you. If as a total load 30% stands and “Controls the DTS Audio Processing object” is at the top, but this does not mean that this is also the problem, it only happens to have the highest RAM load at the moment. The RAM utilization per process permanently increases and if it has a process higher RAM utilization than the others, it naturally lands above when sorting. But that can be quite normal and the actual problems hide in the long list below.

Anyway, for me it sounds like just asking for the sum of all programs 30%, so there’s something in the background that the TaskManager doesn’t show (see Process Monitor) or you’ve installed a lot of garbage that’s summing up.

why does it always attract so much

Because the developers have developed it. I don’t want to write “inefficient” because I can’t judge whether it’s efficient or not. But the fact is: at this moment, the program needs so much RAM and you can’t change it. It may be natural that it requires unusually much RAM due to any other problem or an error, but usually you can’t fix it without a new installation from the program or Windows and then you don’t have a guarantee, but at least a chance. Or the program is manipulated by a virus (virus scanners are not reliable protection against this), then only a new installation from the program or Windows as a whole helps.
