The High Resolution setting in the render queue allows you to use tiled renders to produce larger images than would normally be possible because of maximum texture sizes or memory limits on GPUs. However, it still has some limitations, and the maximum size of the image that can be rendered will depend on the GPU memory and other factors. In your case, the image resolution of 21248 x 2048 pixels exceeds the maximum texture size that your GPU can handle, causing the crash. Scaling down the resolution to 16384 x 1580 allows the render to complete successfully because it falls within the GPU’s maximum texture size limit.

**I also suggest looking at this resource:**

>
> Information over texture support both within the engine and hardware.
