- Issue with rainbow on glass materials is fixed (internal noise map used for all sorts of effects now matches the one in 0.2.11; the upgrade to VS2022 which occurred in preview46 has messed things up);
- Brake discs: initial wear config value is loaded correctly again;
- Extra FX:
  - Fix for a typo in preparation process causing a bunch of effects to malfunction;
  - An old bug with bounced light in triple has been fixed as well;
  - TAA got some fixes for ghosting, now works with custom rendering modes and custom triple cameras override, a few smaller improvements;
  - Accumulation screenshots are working with Extra FX and motion blur in triple again (recent regression);
  - Motion blur doesn’t leak color from side to side with custom rendering modes, blending of blurred regions slightly improved;
  - Look of some windscreen banners with Extra FX TAA fixed;
- Upscalers:
  - New XeSS upscaler (requires Intel Arc GPU);
  - Fallback mechanism doesn’t use NVIDIA Image Scaling if quality is above 100% (it can’t handle that);
  - OptiScaler updated to 0.9, now should have working in-game menu and work on AMD GPUs, shouldn’t interfere with in-game browser;
  - FSR 2 works with triple with different side scales;
  - FSR 3 is loading on-demand;
  - FSR 2/3: reactive mask improved for the image to be a bit less jittery around wheels;
  - Basic upscaler: new “motion test” mode to debug advanced upscalers;
  - Advanced upscalers: MIP bias is fixed, always disabled for accumulation screenshots, compatibility with curved monitor filter improved;
  - Enabling upscaling hides sharpening settings from post-processing antialiasing section;
  - Some upscalers in some configurations are a bit faster, no longer performing unnecessary copying step;
  - Disabling Extra FX live no longer messes up rendering;
  - `dynamic::screen` Lua texture no longer includes flicker;
- Default Weather FX:
  - Some denoise for volumetric fog, both temporal and regular, smoother with TAA, intensity has increased a bit;
  - Lightning is brighter and stays around a bit longer;
  - Sun rays of YEBIS replacement are improved a bit;
  - Auroras fixed, list updated;
  - Sun shadow altering fog backlit is smoothed to prevent flickering, volumetric fog shuts off sooner during sunsets;
  - Outer space shading adjusted;
  - Loading hi-res Earth textures on demand;
  - Lighting with full eclipse fixed, stars are brighter;
- Custom rendering modes (splitscreen, 360°, fisheye):
  - Mouse rays (used for pretty much any mouse-scene interaction) are working correctly;
  - A compatibility issue with upscalers, 360°/fisheye and sharpening in AA settings fixed;
  - `dynamic::screen` Lua texture is working properly;
- Extrapolation of time for online races with Weather FX-configured conditions rewritten, time no longer goes back or oscillates, instead syncing up reliably and smoothly;
- Toggling fullscreen works better when aspect ratio of configured resolution doesn’t match monitor aspect ratio;
- Render stats: more details in compact form, more accurate measurements (frame pacing measurements are excluded);
- Tyres FX damage normals and shading fixed;
- Smart Shadows: adaptive first split is active for bonnet and dash cameras, making shadows sharp with F1 cars again (but still disabled with other drivable cameras, making shadows extend further with chase and bumper cameras);
- Virtual mirror without post-processing looks a bit more sane, trying to mimic YEBIS HDR→LDR step;
- Ctrl+F8 to hide mouse is working again;
- Stalling engines experiment: torque increased, other adjustments, no longer breaks autopilot;
- New option in General settings blocking car and track scripts from accessing web (web API, loading images, streaming via media player, loading GIFs via URLs);
- CSP UI ignores mouse if the window is not actually foreground (affects UI and visual stuff; any physics or audio components still using old way of checking covered percentage of the screen to be extra safe);
- A few small issues caused by old CSP settings with disabled modules are fixed;
- Cables (on configured tracks, such as Laguna Seca):
  - Anti-aliasing improved, now cables are actually a pixel wide, with better fading;
  - Wind animation fixed;
  - Option for track configs to make cables transparent and use alpha-blending instead of previous color (enabled by default);
- A couple of small fixes for keyboard processing that might help with weird bug with camera switch button and similar issues;
- Screenshots flash (on-screen effect, the one disabled by default with accumulation screenshots) is faster;
- New hotkey to make a screenshot without accumulation (by default, Alt+F8);
- Refraction of sun close to horizon fixed (it was working in space instead of working everywhere but the space), a bit of gravitational lensing for stars during a full eclipse event;
- Earth textures and shading updated, thanks to Artemis 2 mission, with a few fixes for Extra FX as well, eclipses are visible from space;
- Photo mode app:
  - Time offset slider shows time properly, with hours and minutes;
  - Press “Enter” when entering the name for a save point in photo app to quickly save it;
- “Tunnel Effect” filter adjusted a bit;
- Fixed AC Pro support (still needs PDB file to be available);
- Default loading script: session name is fixed, other smaller fixes;
- A few fixes for creating screenshots if accumulation is disabled, especially with upscalers;
- Detection for possible issues with Intel CPUs rewritten to reduce false positives, still disabled by default though;
- Custom final stretching is updated to be more compatible with things that might want to inject into AC rendering pipeline;
- Modal dialogs no longer close when taskbar is being opened;
- More logging for positioning AC window, to try and debug some triple configurations;
- Shadows cast by `ksPerPixelNM_UVMult` shader are taking into account diffuse UV multiplier;
- New `ksMultilayer_fresnel_nm5` shader with four per-channel normals and `txDetailNM`;
- If the size for a track display wasn’t configured, and texture size is unknown, CSP will use 256×256 as a fallback resolution;
- New `[WEATHER_FX] CLOUDS_OVER_SCENE=1` for track configs asking Weather FX to draw clouds over the opaque track geometry;
- New `IDEAL` type for digital display materials preserving colors;
- New `CUTS=TANGENT` option for brake discs adding radial lines (configurable via `CUTS_TANGENT_FREQUENCY`, `CUTS_TANGENT_THICKNESS`, `CUTS_TANGENT_MODE`, `CUTS_TANGENT_PIVOT_RADIUS_MULT`);
- New flag for meshes to specify if they should or shouldn’t cast shadows in fourth (distant) cascade, separate from main flag, to fix the issue of distant geometry not casting shadows as expected, can be altered with `[SHADER_REPLACEMENT_…] DYNAMIC_SHADOWS=TERRAIN` (by default is set by new KN5 loader if shadows casting flag is set, old KN5 loader is no longer supported);
- `[SHADER_REPLACEMENT_…]`: new `EFX_SKIP_GBUFFER`, `EFX_MASK_GBUFFER`, `EFX_BLEND_GBUFFER` and `EFX_DELAYED_RENDER` (instead of old malfunctioning ones);
- New `CUBEMAPLESS_REFLECTION=1` for `[SHADER_REPLACEMENT_…]` meant to fix flickering fences on Nordschleife;
- `loading.carSkinID()` is fixed;
- `ac.INIConfig.raceConfig()`, `ac.INIConfig.videoConfig()` and `ac.INIConfig.controlsConfig()`: fixed type of returned config;
- New `ac.getSim().isTAAActive`;
- `table.build()` fixed;
- `ac.isMeshClicked()` and such no longer check LOD B and further, no longer have that false positive at the first frame;
- `ac.ControlButton()`: default modifiers are fixed (a bug introduced on 6th of April 2025);
- `ac.makeScreenshot()`: argument to set accumulation on or off, fix for extension if file name is default, but format differs from JPEG;
- `ac.enableRenderCallback()` of Weather FX styles: new parameter for a callback after all the transparent geometry, but before Extra FX resolution, issue with track callback sometimes called twice fixed;
- `web.timeouts()`: fifth argument overriding maximum number of simultaneous requests;
- New `shared/utils/oswindow` library for creating extra OS windows;
- Few fixes for DWrite text rendering API.
