OpenGL vs Vulkan: which is better for modern graphics?

Vulkan is the better choice for demanding, multi-threaded modern graphics work, while OpenGL remains simpler for smaller projects and legacy codebases. Khronos Group released Vulkan 1.0 in February 2016, roughly 24 years after Silicon Graphics shipped OpenGL 1.0 in June 1992.

When does OpenGL make sense?

OpenGL still works well for tools and internal applications where development speed matters more than squeezing out every frame. Its driver handles memory allocation, synchronization and threading automatically, so a small team can get a rendering pipeline running without writing explicit barrier and fence code. Software that already has a mature OpenGL codebase, such as older CAD applications or legacy game engines, rarely benefits from a full rewrite when the existing renderer meets its performance targets.

When does Vulkan make sense?

Vulkan fits projects where CPU overhead and draw-call count limit frame rate, which is common in modern open-world and VR titles. id Software's id Tech 7 engine, used in DOOM Eternal, renders exclusively through Vulkan on PC because the explicit API lets the engine distribute command buffer generation across CPU cores instead of relying on a single driver thread. The tradeoff is code volume: a Vulkan renderer typically needs far more setup code than the equivalent OpenGL version before it draws its first pixel.

Which one is better for modern graphics?

For engines built for current hardware, Vulkan is the stronger long-term choice, since Khronos has continued extending it (Vulkan 1.3 shipped in January 2022) while OpenGL's specification has not received a major update since version 4.6 in 2017. Projects without dedicated graphics engineers, or those maintaining existing OpenGL renderers, can still ship reliable products without migrating, particularly with layers like Zink that translate OpenGL calls onto a Vulkan backend.
