// Suggestions:
// - You can check memory wastage using "stat d3d12rhi" in a dev build
// - Tune d3d12.ReadOnlyTextureAllocator.MinPoolSize/MinNumToPool/MaxPoolSize
//   according to video memory budget
// - Memory overhead is slightly over 200 MB in internal tests but consider
//   adjusting above cvars or disabling if it fails your use case
// - The purpose of this allocator is pooling texture allocations because
//   creating committed resources is slow on PC. But if committed resource
//   creation ever becomes fast, there is no need for this allocator
