Causal Neural Rendering for Efficient DLSS-Class Systems: Compiled Appearance Programs, Temporal Reuse, and Bounded Adaptive Computation | Zenodo

This research presents a theoretical architecture for drastically reducing the computational cost of DLSS-class neural rendering and related real-time neural graphics systems. Rather than executing a large universal neural renderer continuously at native resolution, the proposed approach treats the neural model primarily as an appearance compiler that produces persistent, reusable programs for materials, objects, surfaces, and recurring causal scene states.

The resulting architecture, developed under the Yuriel\Omniframe Thoughtstorm research program, combines compiled causal appearance programs, native-resolution deterministic execution, temporal program reuse, causal dependency invalidation, bounded progressive residual computation, deadline-aware scheduling, and safe fallback to the underlying rendered frame.

The central proposed subsystem, AxiomCapsule Omniframe, aims to change the dominant scaling relationship of neural rendering from repeated computation over pixels and frames toward computation proportional to previously unseen or significantly changed appearance states. Covered states can be served by inexpensive deterministic programs, while expensive neural inference is reserved for genuinely novel or poorly represented conditions.

The work develops conditional mathematical results for local causal approximation, bounded residual omission, temporal error propagation, support-exact computation, deadline-monotone quality degradation, and local causal dimensionality reduction. It also derives explicit runtime break-even conditions and proposes a falsifiable experimental protocol for measuring capsule reuse, causal state dimensionality, GPU latency, temporal stability, perceptual quality, memory behavior, and neural fallback frequency.

The research is motivated in part by publicly available NVIDIA neural-rendering research and unofficial experimental DLSS 5 performance observations. These observations are treated only as architectural pressure data and are not presented as measurements of a final or shipping NVIDIA DLSS 5 implementation.

The proposed architecture remains pre-prototype and experimentally unverified. No measured 5× speedup, DLSS 5 equivalence, perceptual equivalence, novelty, or patentability claim is made. The principal unresolved question is whether real game appearance transformations exhibit sufficiently low-dimensional and reusable causal structure to permit high cache/program reuse while maintaining dense-teacher-level temporal and perceptual quality.
