Changelog

New features, options and improvements

• Smart Shadows:
  • Fourth shadow cascade for distant shadows and shadows in mirrors (optional);
  • Adaptive distance for first split for exterior cameras (distance is reduced if close to a car, optional);
  • Adjustable blur amount;
• Extra FX:
  • Motion blur shader reworked from scratch to improve performance and quality;
  • Fog blur updated;
• Various optimizations:
  • During loading, new bounding spheres are calculated, smaller and more precise;
  • AABB culling for track geometry, with optional SSE acceleration for reflections;
  • New culling options: forced culling for pieces partially visible cars, orientation-based culling;
  • Occluders-based culling (occluders are defined via track config);
  • Reworked cubemap and shadows reflections rendering for more straightforward and faster rendering;
  • Option to reproject reflections cubemap to get smoother transition with partial updates;
  • FidelityFX: with UAV flag for output (optional), no extra copy is necessary, saving some time;
  • New performance analyzer app with graphs and detailed measurements (going to replace Render Stats later);
  • Some Python apps without visible windows now go to sleep mode to speed things up;
  • Python apps profiler updated, now showing nicer average and max (averaged) time;
  • Extra FX: building light map for bounced light is now faster;
  • IMGUI blending (used by new CSP apps and more) is no longer slow;
  • Option to disable car shadows for third cascade for interior and exterior views;
  • WeatherFX: experimental option to run garbage collector or optional maintanence processing in a separate thread;
  • A few smaller optimizations;
• Separate parameters for number of visible cars for exterior views, slightly higher by default;
• Reflections cubemap: prefilter option to get rid of pixels;
• Working cubemap reflections in mirrors;
• MSAA tweaks: resolve with tonemapping to improve quality, optional custom kernel for smoother image;
• Brake Disc FX: procedural cuts for more complex look;
• New CSP apps now can be pinned from context menu of their title bar;
• No more clearing color buffer (optional, help with performance and small holes in some tracks a bit);
• New option (set via track config) to align trees lighting with surface underneath, helps to improve look of hilly tracks;
• Navigators now remember the type of camera previously used;
• CSP would try and fix missing windscreen shader, as well as apply skip G-buffer flag to dashboard glass;
• Option to force headlights for other cars online in Weather FX section;
• Color grading: GPU-accelerated conversion, now 16-bit and square non-HALD color LUTs are properly supported;
• GrassFX is enabled by default now;

Fixes

• Tyres FX fixed;
• Backlit glass shader fixed;
• FidelityFX CAS now applied after FXAA 3.11 and such (CMAA2 was fine);
• Improved main form detection for the new taskbar;
• Dynamic shadows fixed:
  • Flickering shadows in distance fixed;
  • No more occluding light on tracks like Shuto;
  • Headlights range fixed;
  • Proper look for lower poly geometry;
  • Multiple headlights for a single car now have proper dynamic shadows;
• GrassFX rarely messing up motion blur and looking all buggy fixed;
• Disabling CJK symbols fixed;
• CJK symbols consume less VRAM and don’t cause a freeze upon race start anymore;
• Ghost car obscuring view with strange artifacts fixed, as well as its refraction (disabled by default);
• Helmets now don’t receive sun light in mirrors in enclosed cars fixed and cast proper shadows in first person view;
• Shadows filtering adjusted to reduce artifacts, shadows from distant geometry fixed;
• Missing car details in mirrors fixed;
• Timezones sanity check on launch fixed (no more messed up lighting);
• No-shadows and no-lighting shader sets were removed to improve loading speed;
• Refracting lights TAA no longer adds that much lag, also sharper in screenshots;
• No more pieces spawned from collisions with non-mesh car colliders (those usually are for bottoms and skid blocks);
• Virtual mirror no longer messes with UI;
• DXGI flip mode is no longer available in full screen, as it should have been from the start;
• CSP radar app now fades properly;
• CSP driver tags work properly with post-processing disabled;
• Motion blur won’t overly blur everything right after camera jumps;
• Baked fake shadows or car wetness maps now rebuilt if model changes;
• Actual car model (lowest LOD) now used to calculate car dimensions, because, as it turned out, colliders of some mods are badly misplaced;
• Misshaded static tyre marks fixed;
• Ground height estimation fixed for extreme cases (such as when there are holes in the ground nearby);
• SSLR misbehaving in fog fixed;
• Python function ac.ext_getTyreBlister() no longer crashes AC in certain cases;
• New flames better compatible with SSLR;
• Distant blug for fog blur effect removed (fog-based only is enough);
• Compatibility with AC PRO fixed;
• Negative mip bias in AC video settings no longer affects performance of GrassFX map generation and such;
• Issue with disappearing distant emissives fixed, improved look in reflections;
• Car shadows appear in third shadows cascade, overall rendering improved;
• More cars visible in high details at once;
• New main menu is centered in the middle for triple screen;
• Car paint won’t mess up carbon by default now;
• Extreme specular parameters for car paint won’t result in crazy glare;
• Shader ksPexPixelAlpha now functions correctly if alpha parameter is above 1;
• Live reload of color grading textures in PP editor fixed;
• WeatherFX: frustum test now has an extra argument to stop heading adjustment;
• New photo app: motion mode now doesn’t reset orbit camera;
• Distant emissives work with moving objects (such as ferris wheels);
• Few smaller bugs and crashes fixed;

Configs

• Support for BC7 DDS compression (takes the same as DX5, looks much better);
• New app to arrange track occluders: walls and boxes;
• New mesh filtering keywords: flag static for static track meshes, flag castsShadows for meshes casting shadows, number largerThan checking bounding sphere radius;
• Culling mode for dynamic lights shadows is adjustable now, with default changed from double to front-facing;
• Now it’s possible to disable volumetric lights for some headlights;
• Car inputs: no more zeroing for stalled by default;
• Extra car animations: hold final state, blend several animations together, blend animations with regular steering animations (can be used for handbrake animation);
• Original car animations: apply LUT and other postprocessing to alter keyframes selection;
• Shader replacement: if file for texture replacement is missing, whole thing would be ignored;
• Car paint shader updated (new ApplyMatteFix parameter, applied automatically for v3);
• Track lights now can skip cars to speed things up;
• Track meshes can stop casting dynamic shadows;
• New Python functions: ac.ext_pauseWhenHidden(frames), ac.ext_isAnyAppVisible();
• New track config value: [WIND] DYNAMIC_FLAGS_TESSELLATION=1, change to 0 to deactivate tessellation;
• New G-buffer flag ALPHA_TEST_GBUFFER to enable alpha testing, using ksAlphaRef as threshold;
• New INPUT_REFRESH_RATE option allowing to set custom refresh rate in Hz, 5 Hz by default for digital instruments;
• Extension configs, both for cars and tracks, now can access track’s data;
