Yeah, I'm just now testing mid-tier devices and it's also performing a
bit worse for high throughput workloads. But I hadn't really tried to
tune the settings here, and maybe my criteria is all wrong. I was mainly
trying to see if we can utilize the dim library before honing in on the
right implementation details.
