GpuShift 1.2.7 – Entity Preview & Flicker Hotfix

Special thanks to NoahRoopull for reporting the issue and providing the files needed for testing.

Fixed Fixed entity previews from Supplementaries and similar mods being incorrectly affected by Smart Entity Culling. Preview and detached entities are now automatically protected, including mobs displayed inside cages, jars, books, held items, and custom preview renderers. Fixed distant mobs flickering when the adaptive render distance changed under frame pressure. Replaced the old short cache with stable spatial and temporal hysteresis. Entities are now culled only after remaining beyond the distance threshold for several consecutive frames. Prevented temporary previews and reused entity IDs from inheriting cached culling decisions from real world entities. Preserved all existing protections for players, named or glowing mobs, passengers, nearby entities, and important entities. Kept the fix fully compatible without adding a hard dependency on Supplementaries. Performance World registration checks only run for distant entities that may actually be culled. Fast render paths remain unaffected. No noticeable performance loss was observed in scenes containing more than 100 mobs.

GpuShift GPU V2 Beta

Highlights

• Added the new GPU Mob Layer for supported adult vanilla passive and neutral mobs.
• Mob animations are prepared on the CPU, while vertex transformations and instanced rendering are handled by the GPU.
• Added automatic batching by model, mesh, and texture to reduce entity draw calls.
• GPU rendering activates for distant mobs when at least four compatible models are visible.
• Added automatic model discovery, mesh caching, bone hierarchy extraction, and safe vanilla fallback.
• Unsupported entities, children, passengers, glowing or invisible mobs, damaged states, custom models, and modded entities remain on the vanilla renderer.
• Vanilla shadows, names, leashes, fire, armor, wool, saddles, and additional render layers remain fully supported.
• Added safe compatibility detection for shader, model, and texture replacement stacks.
• Added GPU Mob settings, status information, capture counters, fallback counters, batch counts, instance counts, and draw-call statistics to the GPU V2 interface.

Smart Calibration

• Replaced the basic Auto Tune toggle with a complete Smart Calibration system.
• Detects the current hardware, rendering environment, active resource packs, shader stack, resolution, render distance, and performance bottleneck.
• Tests particle density, entity distance, Block Entity distance, item-frame budgeting, GPU Particles, GPU Mobs, and Adaptive Mode independently.
• Automatically skips tests when the current scene does not contain enough relevant workload.
• Searches for the best combined configuration using up to 16 controlled probes.
• Validates the final recommendation using an alternating A-B-B-A test.
• Tracks average FPS, 1% Low, p99 frame time, stability, and result confidence.
• Repeats invalid measurements when the player moves, rotates the camera, opens a screen, changes worlds, or loses window focus.
• Temporarily removes VSync and FPS limits during calibration, then safely restores the original settings.
• Trial settings remain runtime-only until the player presses Apply.
• Added recovery protection for interrupted or crashed calibration sessions.
• Saved calibration results are automatically marked as outdated after significant system or rendering changes.

GPU Mob Lighting Fix

• Fixed GPU-rendered mobs appearing completely black in darkness or when a shader mod was installed without an active shader pack.
• GPU Mob rendering now explicitly binds the vanilla lightmap and overlay textures.
• Added safe restoration of texture bindings and OpenGL state after every GPU batch.
• Added automatic vanilla fallback when required auxiliary textures are unavailable.
• Added the new fallback status: AUX_TEXTURES_UNAVAILABLE.
• Added a one-time log confirmation when the mob shader, texture, lightmap, and overlay bindings are ready.

Stability and Compatibility

• Added safe fallback for shader initialization failures, resource errors, unsupported render types, buffer overflow, and unavailable GPU resources.
• Resource reloads, dimension changes, disconnects, and world changes now clear and rebuild GPU Mob resources safely.
• Added protection against permanent mob disappearance after rendering or shader errors.
• Added support for Sodium and Embeddium rendering environments.
• Added SAFE and FORCE operating modes for GPU Mob rendering.
• Reduced runtime telemetry overhead outside active calibration.

Benchmark Results

• Average FPS improvement: +8.4%
• 1% Low FPS improvement: +14.0%
• Frame time improvement: approximately 0.16 ms
• Deep 0.1% Low frame drops did not worsen.
• Results were collected across three clean benchmark cycles and are included in the benchmark graph.

GpuShift 1.2.6 Early Config Load Crash Hotfix Fixed the NeoForge startup crash: Cannot get config value before config is loaded. GpuShift now safely waits for the client config to finish loading before enabling optimizations. Existing settings are applied automatically after loading, with no restart or config reset required. Added startup protection for GPU Particles, Block Entity budgets, overlays, desktop UI, and config controls. Released for Minecraft 1.21.1 and 1.20.1.

Special thanks to Gopnik for the detailed crash reports and help identifying the issue.

GpuShift 1.3.0 Beta 1

GPU Particle Layer v2

• Added a new experimental GPU particle renderer for Minecraft 1.21.1.
• Particle movement, gravity, fading and billboard calculations are now handled by the GPU.
• Added AUTO, V2 and VANILLA backend modes.
• Smoke, ash and suspended particles can use the new renderer.
• Unsupported, modded or incompatible particles automatically fall back to vanilla rendering.
• Pretty Rain, FBP, weather, leaves and campfire smoke remain vanilla.
• Unsupported GPUs and shader errors safely disable V2 without crashing.
• SAFE mode disables V2 with Iris/Oculus, while FORCE allows experimental testing.

Bottleneck Detector

• Added automatic detection of CPU-bound and GPU-bound situations.
• Adaptive Mode can now adjust particle, entity and block-entity budgets based on the detected bottleneck.
• GPU timing is asynchronous and does not wait for the GPU.

UI

• Added GPU backend selection.
• Added Bottleneck Detector toggle and status.
• Debug overlay now shows GPU particle instances, fallback count, draw calls, CPU/GPU frame time and bottleneck state.

Benchmark

Compared with stable 1.2.5:

• Average FPS: 140.75 vs 140.37
• p95 frame time: 9.29 ms vs 9.53 ms
• p99 frame time: 10.95 ms vs 11.78 ms
• 1% Low: 39.77 FPS vs 36.79 FPS

Average FPS is effectively unchanged, while heavier frame-time spikes and 1% Low performance improved.

GpuShift 1.2.5 Hotfix

This update improves compatibility with particle and block entity rendering mods.

Fixed

• Fixed block-like particles disappearing when the Particle Budget was set below 100%.
• Improved compatibility with FancyBlockParticles and similar particle mods.
• Fixed chests, signs, banners, campfires, beds, and shulker boxes disappearing with some block entity rendering mods.
• Improved compatibility with Better Block Entities, OBE, Enhanced Block Entities, and FastItemFrames.
• Normal GpuShift optimization behavior remains unchanged when these mods are not installed.
