- Resource barriers are now batched and submitted as a group at the beginning of a pass.
- UAVs referencing the same underlying resource now only submit a single write barrier instead of a write + N UAV barriers.
- During a mip generation pass, barriers are not issued for textures (they are implicitly converted to the SubRWBarrier state).
- Depth / stencil read now transitions to the read state; this allows DSV + SRV to work correctly.
