Diablo 4 high memory usage in Windows 11

Memory, or RAM (Random Access Memory), is one of the most important components of your PC that affects its performance and speed. Memory is where your PC stores and accesses the data and information that it needs to run programs and applications, such as Diablo 4. The more memory you have, the faster and smoother your PC can run multiple tasks at once.

Well, a memory leak (High Memory usage) is a situation where a program or a process uses more and more memory over time without releasing it back to the system. This can cause the system to run out of memory and slow down or crash other programs. In the case of Diablo 4, the memory leak issue seems to be caused by some graphical settings that are not optimized for the game. These include the texture quality, the draw distance, and the fullscreen mode. These settings can affect how much memory the game uses to render the game world and its elements.

  • Running the game at ultra-high graphics settings, especially on systems with limited RAM or VRAM, may lead to increased memory usage.
  • Outdated or incompatible GPU drivers can contribute to memory leaks and increased usage.
  • Compatibility problems between Diablo 4 and certain hardware configurations or software components can result in high memory usage
  • Background processes and other running applications can consume system resources, including memory.
  • Game software may sometimes have memory leaks or bugs that lead to increased memory usage over time.
  • Certain third-party software, such as antivirus programs or performance optimization tools, may interfere with game processes and contribute to memory usage issues.
