v1.0.6 DLSSNR Cost Scaler

DLSSNR-Cost-Scaler is a standalone DirectX 12 proxy for NVIDIA DLSS-NR (nvngx_dlssnr.dll) that decouples neural model resolution from display resolution.

Highlights

• Resolution Scaling & Cost Slider: Run internal DLSS-NR model reconstruction from 25% to 200% of native resolution (from high-performance sub-sampling down to 4K Super-Sampling / SSAA).
• Zero-Overhead Dynamic FPS Scale Governor: Automatically adjusts internal neural resolution in discrete 5% tiers to lock in your target framerate (30–240 FPS) with instant slot caching and zero idle VRAM overhead.
• Frame Generation Target Mode: Target final displayed framerates directly when using 2x, 3x, or 4x frame generation.
• Anamorphic / Asymmetric Neural Scaling: Scale horizontal and vertical axes independently (e.g. 0.65x X / 0.85x Y) for ~45% neural cost reduction with near-native vertical clarity and flat, stutter-free frame pacing.
• Matched Residual Resolve: Composites the neural lighting delta back onto the untouched 1:1 native frame, preventing upscale blur on geometry, textures, and UI.
• Chromaticity-Preserving Color Control: Strips neural color casts without chalky or pastel desaturation, keeping native scene contrast and vibrant saturation intact.
• Depth-Aware Bilateral Silhouette Preservation: Uses the native depth buffer to guard geometric boundaries, preventing low-resolution neural radiance from bleeding across character or vehicle silhouettes.
• Hardware TMU & LDS Acceleration: Downsampling runs directly on GPU texture units, and RCAS runs in on-chip Local Data Share (LDS) for ~69% fewer global VRAM reads.
• Color & HDR Support: Full compatibility with SDR, HDR10 PQ, scRGB (FP16), and true native UAV support for 3-channel HDR (R11G11B10_FLOAT).
• Live INI Hot-Reloading & Companion Overlay: Full bidirectional sync between nvngx_dlssnr.ini and the ReShade companion UI (dlssnr-companion.addon64).
• Silent Hotkeys:
  • Ctrl + Alt + Space — Toggle proxy ON / OFF
  • Ctrl + Alt + End — Toggle Matched Residual vs Bilinear
  • Ctrl + Alt + PageUp / PageDown — Adjust scale by ±5%

What's Changed in v1.0.6

• Zero-Overhead Dynamic FPS Scale Governor:
  • Automatically shifts internal neural resolution in discrete 5% stepped tiers to maintain your target framerate budget (TargetFps, 30 to 240 FPS).
  • Asymmetric Hysteresis State Machine: Prompt step-down after 1.0s sustained deficit (<0.95x target) to rescue dips quickly; patient step-up after 3.0s sustained surplus (>1.15x target) with a configurable dwell cooldown (HysteresisSec = 2.0s) to eliminate scale oscillation.
  • Spike & Outlier Protection: Rolling EWMA frame timer filters out transient loading screens, pause menus, and alt-tab spikes (>80ms) so the governor never false-triggers.
  • Lazy Zero-Stutter Slot Caching: Caches visited resolution tiers across existing slots; switching between visited tiers is an instantaneous 0.00ms pointer swap with zero feature-recreation hitches.
  • Zero Idle VRAM Penalty: When the governor is OFF, only 1 slot is ever allocated (0 MB extra VRAM). Toggling the governor off immediately flushes secondary cached slots back to baseline.
• Frame Generation Target Mode (EnableFgMode & FgMultiplier):
  • Built-in multiplier compensation for frame generation setups (NVIDIA DLSS-G, AMD FSR 3 FG, Lossless Scaling, RenoDX MFG Unlock).
  • Allows targeting final perceived framerate (e.g. 120 FPS or 240 FPS) — the proxy automatically computes the required base engine framerate (TargetFps / FgMultiplier) so your game never underscales.
  • Added clean quick-preset buttons in companion UI: [2x] (DLSS-G / FSR 3), [3x], and [4x] (AFMF / Lossless Scaling / MFG).
• Chromaticity-Preserving Color Control:
  • Refactored CS_Resolve to use safe proportional luminance scaling when adjusting ColorStrength.
  • Setting ColorStrength = 0.00 now cleanly removes neural color/temperature tints without introducing chalky, washed-out pastel desaturation, while safeguarding against division-by-zero on HDR highlights.
• Uniform Super-Sampling Pipeline Fix:
  • Resolved an issue where uniform 150% and 200% scales bypassed the scaled neural reconstruction pipeline.
• Companion UI & Live Telemetry Polish:
  • Dynamic Resolution slider now reflects live governor scaling in real-time with an active [GOVERNOR: XX%] badge.
  • Dedicated Governor section featuring real-time FPS/frametime readouts, state badges ([STABLE], [COOLDOWN], [STEPPING DOWN], [STEPPING UP]), and performance headroom metering.
  • Extended clipboard diagnostics to export governor state, active slots, and target metrics.

What's Changed in v1.0.5

• Anamorphic / Asymmetric Neural Scaling (Stutter-Free Widescreen Optimization):
  • Added independent Horizontal ($X$) and Vertical ($Y$) resolution scaling (EnableAnamorphic, ResolutionScaleX, ResolutionScaleY).
  • Decoupling axes on 16:9/widescreen displays (e.g. 0.65x Horizontal $\times$ 0.85x Vertical) yields ~45% neural cost reduction while retaining 85% vertical edge acuity to avoid horizontal line crawl.
  • Flat, Stutter-Free Frame Pacing: Unlike alternating-frame techniques (VRNR) that produce 30Hz sawtooth pacing fluctuations, anamorphic scaling evaluates every single frame at an identical cost, ensuring rock-solid frame delivery with zero micro-stutter.
  • Independent Motion Vector Scaling: DLSSNR.MVecScaleX and DLSSNR.MVecScaleY are dynamically scaled per-axis (workW / nativeW, workH / nativeH), completely eliminating motion smear during fast pans and driving.
  • Added companion UI controls: toggle checkbox, dual sliders, live neural load feedback, and quick presets (Widescreen 0.65x/0.85x, Ultra-Perf 0.50x/0.75x, Quality 0.80x/0.90x).
• Super-Sampling Support (0.25x – 2.00x / 4K SSAA & Photo Mode):
  • Expanded internal resolution scaling from 0.25x - 1.00x up to 2.00x (200% Super-Sample / 4x pixel sample density).
  • Enables DLDSR-grade neural reconstruction and extreme fidelity capture for photo modes and high-end GPUs.
  • Added quick presets in the companion UI: 150% (Photo Mode) and 200% (4K SSAA).
• SEH Crash Shield (Addon & Injector Interop):
  • Integrated Structured Exception Handling (__try / __except) into the proxy hook inspector (HookSnippetCallerCheck).
  • Shields against memory access violations (0xC0000005) caused by third-party hook injectors (such as renodx-mfgunlock.addon64 or custom loader stubs) executing from non-standard memory segments or unmapped code pages during launch.
• Depth-Aware Bilateral Silhouette Preservation:
  • Bound native depth buffers into CS_Resolve to detect geometric silhouettes.
  • Attenuates neural radiance bleeding across object edges, keeping foreground contours (weapons, vehicles, hair) razor-sharp against distant backgrounds.
  • Added runtime dimension checks: gracefully falls back to a neutral dummy buffer if depth dimensions mismatch the backbuffer, preventing GPU device removals.
• D3D12 UAV Format Compatibility Overhaul:
  • Corrected format remapping for R11G11B10_FLOAT (32 bpp) to natively support UAV creation without illegal 64-bit cross-casting.
  • Guarantees zero DXGI_ERROR_INVALID_CALL / DXGI_ERROR_DEVICE_REMOVED crashes on modern HDR pipelines and RenoDX hooks.
• G-Buffer & Subrect Auto-Synchronization:
  • Automatically queries and synchronizes DLSSNR.InputWidth/Height, DLSSNR.OutputWidth/Height, and DepthSubrect / MVecSubrect to match working resolutions, preventing internal NGX kernel assertion failures when G-buffers are supplied.
• Diagnostics & Companion Polish:
  • Clipboard diagnostics and telemetry now output explicit anamorphic dimensions and neural load calculations.

What's Changed in v1.0.4

• Caller Parameter Passthrough by Default (OptiScaler & RenoDX Compatibility):
  • The proxy no longer stomps upstream DLSS-NR parameters set by callers like OptiScaler or RenoDX. Whatever you configure in OptiScaler's GUI, RenoDX, or game menus flows directly into NVIDIA's neural engine untouched.
  • Added UseCustomSettings = 0 (default) under [DLSSNR_Settings].
  • Added an "Override Caller NR Settings" checkbox in the ReShade companion UI with automatic control dimming (ImGui::BeginDisabled), allowing you to opt into proxy-side overrides only when desired.
• Hardware Bilinear TMU Downsampling (CS_Downsample):
  • Replaced manual 4-tap ALU box filter math with single-cycle GPU Texture Management Unit (TMU) sampling via static linear clamp samplers (s0), cutting shader register pressure and ALU overhead.
• LDS On-Chip Tile Caching (CS_Resolve):
  • Integrated 1.2 KB of Local Data Share (LDS) per threadgroup into the matched residual resolve pass.
  • RCAS contrast-adaptive cross-sampling now reads from on-chip shared memory instead of redundant global VRAM transactions, dropping memory requests by ~69%.
• In-Place Resolve & VRAM Footprint Reduction:
  • In engines and integrations where the output buffer already exposes an Unordered Access View (UAV), the resolve compute pass writes directly to the backbuffer without allocating intermediate full-res scratch textures.
  • Saves 66 MB to 132 MB of physical VRAM per active feature slot.
• D3D12 Stability & Crash Prevention:
  • Remapped typeless depth stencil formats (D32_FLOAT, R32_TYPELESS, R24G8, D16) to valid readable shader resource views (SRVs) and added strict dimension/format validation.
  • Prevents DXGI_ERROR_DEVICE_REMOVED / DXGI_ERROR_INVALID_CALL crashes across complex mod configurations.
• Diagnostics & Telemetry Polish:
  • The ReShade companion UI now displays real-time telemetry (color formats, active slots, G-buffer dimensions, caller passthrough status).
  • Added a "Copy Debug Info to Clipboard" button for instant troubleshooting and bug reporting.

What's Changed in v1.0.3

• Stability & Crash-Proof Bypass:
  • Toggling proxy on/off or scaling to 100% native no longer triggers DXGI_ERROR_DEVICE_HUNG / DXGI_ERROR_DEVICE_REMOVED. All slots pass through cleanly without destroying cached features mid-execution.
  • Increased feature and texture retirement latency to a safe 64-frame buffer, guaranteeing GPU command queues are fully drained before freeing resources.

  • Fixes the 16 GB VRAM runaway and 4–5 FPS drops when adjusting resolution in-game.
• Multi-Pass Denoising Support:
  • Fixed pipeline flickering in chained multi-pass DLSS-NR integrations.
• Color Strength Control (Closes #5):
  • Added a dedicated ColorStrength slider (0.00 to 1.00) in both the ReShade companion UI and nvngx_dlssnr.ini.
  • Decomposes neural edits into luminance vs chroma, allowing you to completely eliminate neural color/tint shifts while retaining full ray reconstruction lighting and detail.
• DirectX 11 / G-Buffer Subrect Sync (Closes #4):
  • Fixed startup crash in The Elder Scrolls Online and other RenoDX titles using R11G11B10_FLOAT and native-res G-buffers (Depth, MVec) by properly feeding subrect bounds and format-matched UAVs.
• Bidirectional Config Sync:
  • nvngx_dlssnr.ini is now the true single source of truth: modifying values on disk updates the ReShade companion UI live on the fly, and companion UI edits flush directly to disk.
