Why don't Android Studio and IntelliJ IDEA utilize the GPU more effectively for rendering and performance, especially when handling heavy UI elements or large projects?

Are you sure that CPU usage is due to graphics tasks?

I realized that most of the CPU usage actually comes from *code analysis, indexing, lint checks, and Gradle-related tasks*, not graphics rendering

I'm more curious why JetBrains IDEs *don’t use GPU acceleration at all*, even for UI rendering, considering modern GPUs could handle that more efficiently. It might not solve the CPU load from builds or indexing, but it could still improve responsiveness.

I’m not sure how it can be achieved, but maybe JetBrains IDEs will support better GPU utilization in the future

It was just something I was wondering — why the GPU isn’t used, so I asked the community to see if it’s possible.

IntelliJ does use GPU acceleration, through Java's Swing toolkit. although how that works is up to Java

JetBrains has worked on parts of it upstream, such as a Apple Metal renderer <https://blog.jetbrains.com/platform/2020/11/metal-for-intellij-platform/>
