Although there haven’t been any media updates by Portkey Studios regarding the CPU strain that Hogwarts Legacy can cause on most systems. Several educated assessments can be made about the current optimization of the game.

The most important of which is the inclusion of Denuvo in Hogwarts Legacy. The Denuvo software is an anti-cheating and anti-piracy software that has recently become a common fixture in recent triple-A game releases. The problem, however, is that it places a massive strain on the CPU and client system.

This means that even if you bought the game legitimately, you will have to face various processing issues and poor optimization. Even if Denuvo is ignored, it is safe to say that the game’s graphical requirements are quite high. Owing to being an open world several assets need to be generated and managed.

So it makes a lot of sense to conclude that Hogwarts Legacy would place stress on most lower-end PCs and even give the latest PCs a run for their money. Poor optimization is the reality of most triple-A-developed games nowadays and it is a tragic truth.

A common issue many gamers face is not meeting the system requirements of the latest releases. And it can be quite bothersome trying to keep up with the cost of rapidly growing technological requirements. But these are facts that we simply cannot ignore.

Check the minimum requirements for the game below and ensure your system meets the basic criteria. You might also want to consider running the game on the lowest graphical settings. So that it reduces the burden on your PC.

2. Allowing Shaders To Finish Compiling

A major reason why your game might currently be taking a lot of computing resources is that it is compiling shaders. Immediately after running Hogwarts Legacy, many of you might have experienced a screen that denotes a progress bar saying Compiling Shaders.

These Shaders allow the game to construct its graphical landscape and objects according to its physics engine. This is highly CPU intensive, but not necessarily a problem. Allow this process to run till completion and wait 5-10mins after it is complete.

Your CPU usage should drop back down to normal afterward. Especially, since this process allows for the active burden on your CPU to be reduced significantly. This means that all you have to do is be patient to fix the issue.

3. Stop Background Operations and Processes

An important thing to realize is that there are always additional background apps that Windows is running. You might not even realize how many of these processes are currently working, and are eating your CPU resources. A stressful game can cause the issues caused by such programs to flare up.

Eventually, this might lead to slowdowns, or in the case of Hogwarts Legacy 100% CPU usage. It is thus quite a good idea that you consider Quitting/ Exiting many of the useless or currently irrelevant programs that you might have running on your PC.

This will allow essential processes to complete. It also means your PC will have more resources to accurately complete processing and loading for the game. And not increase the usage of the CPU.
