* This means that using a VkPipelineCache per PSO will explode system memory usage, leading to OOM.
* To counteract this, we use one global pipeline cache instead, but this means we lose the ability to
* serialize and unserialize PSO state. Instead, we can just serialize garbage and ignore unserialization.
* From a correctness PoV, this is perfectly fine, and cached PSOs should be present in disk cache either way. */

* The bug was introduced in 470 series, but was fixed as of 470.62.02 driver.
