: It specifically improves performance on high-DPI screens where software rendering often fails to keep up. How to Enable GPU Acceleration

GPU accelerated rendering refers to the process of using a computer's Graphics Processing Unit (GPU) to accelerate the rendering of graphics and text on the screen. Unlike traditional CPU-based rendering, which relies on the Central Processing Unit to handle graphical computations, GPU accelerated rendering offloads these tasks to the GPU, freeing up the CPU to focus on other tasks.

In previous versions like Sublime Text 3, software-based rendering (using the CPU) struggled with larger screen real estate, such as 4K monitors. As resolutions increase, the number of pixels the CPU must calculate grows exponentially, leading to noticeable input lag and "choppy" scrolling.
