Project CARS – Xbox One Patch 1.3 - Issues Addressed


Gamepad Controllers:
* Added ABS brake rumble to Xbox One triggers, so that the triggers will rumble on losing traction when braking. The amount of trigger rumble is controlled together with Force Feedback strength via the Force Feedback slider.
* Improved the efficiency of the controller rumble effect, to help make the steering more responsive on the Xbox One.
* Fixed an issue where moving the sticks from one extreme to the other would sometimes result in the steering getting stuck.
* Reworked the Xbox One analogue sticks range and axis dead zones, providing much improved steering control.

Wheel Controllers:
* Fanatec wheels – Fixed the issue with steering jolts that some users experience.

Online:
* Fixed an occasional crash when advancing from Qualifying to Race.
* Fixed an occasional crash when returning from a race to the Race Central.

Time Trial:
* Set Time Trials starting time to 11am to match the PC platform. This ensures consistent track temperatures across all platforms, as track temperatures affect lap times.

Ghosts:
* Enabled saving of community event ghosts. These ghosts are automatically stored online, and you can then download ghosts of other players’ laps for these events.

Tracks:
* Sakitto and Summerton variations - Corrected track info regarding number of turns and track length.
* Sakitto Sprint - Fixed a crash that would at times occur when using time acceleration.
* Cadwell variations - Fixed draw distance issues on various objects.
* Oschersleben variations - Fixed odd lights around track and colour issues with the horizon.
* Zolder - Fixed an issue where the player car would sometimes start in a closed garage.

AI:
* Fixed an issue where AI vehicles were sometimes sent to the pits due to low fuel on races where refueling is not allowed.

Pitstops:
* Pitstop strategy will now use the actual bar value for tyre pressures.
* Fixed an issue where the Pit engineer would repeatedly inform the player that a pit crew member has lost a wheel nut during pit stops.
* Fixed an issue where the Pit Engineer would call the player to stop for fuel when fuel consumption was disabled in options.

Replays:
* Improved the smoothness of the sun, moon, stars, and shadow motion when rewinding replays of a race that had a high time acceleration.

Driver Network Profile:
* Fixed an issue where at times the miles driven on a particular track or with a particular car would be logged under the wrong car or track. This improves the accuracy of the player’s Affinity ratings.

Project CARS – Xbox One Patch 1.3 - Release Date May 28th

-Addresses above issues


Project CARS – Xbox One Patch 1.4 - Tentative Release Date June 2nd

-This DLC should include the Bentley and the IMSA Audi 90 GTO
-Possibly a few other cars and liveries
-Maybe a track and/or added track configurations
-Frame rate enhancements
-Some minor tweaks (sound/graphics)

There is a community event that goes live on June 5th that requires the Racing Icons car pack.

After installing the game patch, do a hard rest of the system. Your total game size should be 18.7 gb

For controller users, remember to cycle through the controller input type (1,2,3), after you download the patch.  This will reset to default settings, then adjust from there, input 3 seems to be a good starting point.

Hired has a settings thread HERE, if you find something that works for you, it may help others.

Project CARS –Patch 1.4 – Release Notes

General
* Pagani Monza Clubday invitational event - No longer causes the game to crash when using a specific livery on the Pagani Huayra.
* PC - Fixed an issue that would cause the game to crash while watching saved replays, when shared memory is enabled.
* PS4 - Anisotropic filtering has been increased to help reduce blurry textures.
* PS4 - Temporal anti-aliasing has been further optimized. This reduces the ghosting effect and additionaly gives the player full control via a slider to tweak the resulting image according to personal preference.

Performance improvements
* Xbox One - Various performance optimizations, adding up to an average of 5-6% performance improvement. This results in an overall smoother experience.
* PS4 - All shaders have been rebuilt using new shader compiler, giving a significant performance boost in some areas.
* PS4 - CPU performance gains due to new more aggressive code optimisations.

Physics & AI
* The AI loss of grip that results from tyre degradation as a result of wear is now more noticeable.
* The AI will now show much more realistic grip loss when running on slick tyres in the rain.
* First pass improvements on various tracks to enhance the AI performance and ability (Azure Circuit, Donington GP, Watkins Glen, Bathurst, Nordschliefe)

Pitting, tuning, setups
* Fixed an issue where certain street cars would pit for tyre change during rain when they already had the correct tyres fitted.
* Fixed an issue where custom vehicle setups were lost when progressing through sessions.
* Improved the system used to select the most appropriate tyres based on current and predicted weather conditions.
* Ensure that the AI always pit when they need to change tyres based on the weather conditions.
* The Default strategy will now correctly show the tyres that will be fitted on the player vehicle during a pit stop.
* The pit stop routine will no longer start during online races until the player closes the pit stop menu. This ensures that the player has enough time to select or configure an appropriate set of actions before the pit crew start working on the car.
* Tyre pressures will now be correctly set when the player changes to a new set of tyres.
* The currently-active Pit strategy will now remain in action when advancing through race sessions.

Online
* Fixed an issue where the player was sometimes given a large time penalty when exiting the pit lane.
* Fixed an issue where the remaining session time displayed an incorrect value in the Tuning screen.

Project CARS – Patch 2.0 – Release Notes

Performance Improvements
* PC – up to 5% frame rate improvement when using Ultra settings
* XB1 – up to 17% frame rate improvement in extreme conditions

Online & Community Events
* Multiplayer search filter 'Skill' now finds games based upon certain lobby game configuration criteria. For example, “Pro” setting now searches for Full Damage, Auto-start Engine, Forced Cockpit, Mechanical Failure, and so forth.
* Community events page – when an event cannot be entered, it will now display the reason why: ‘Coming Soon’ along with a countdown, or ‘Expired’.
* Online – Ensure that vehicle light repairs are synchronized in MP races so that repaired headlights are visible by other racers.
* Xbox One - fix attempt for a hard-to-reproduce issue where the game would at times freeze or crash when 8 or more players joined a session all at once.
* Xbox One – fixed an issue that at times would prevent a player from establishing full connectivity when leaving a lobby and trying to reconnect to it.
* PS4 – fixed an issue where, after the PS4 resumes from Rest Mode, no network features can be used.

Controls – All platforms
* Adjustments made to the gears system, to prevent gears being skipped under certain conditions. This addresses an issue where gears would at times jump straight down to 1st, potentially causing engine blowouts.
* Steering wheels – reduced the centering rate of the steering spring. This improves the feel of steering wheels at very low speeds.
* Added support for the use of all active controllers for menu input. You can for example now use a steering wheel to race, and a gamepad to control the menus and photo mode.
* Gear shifters – when using an H-shifter on a car that has a sequential gearbox, the gearbox will now switch through the gears until the gear selected on the H-shifter is reached.
* Fixed an issue in Force Feedback calibration that would prevent a player from setting "Soft Clipping (Half Input)" back to 0 after modifying it from the original value.

Controls – PS4
* Thrustmaster T100 Force Feedback improvements.
* Fixed the Force Feedback dynamics for wheels with physical steering locks which were less than the steering lock of the vehicle in-game. This fixes the Force Feedback on the Thrustmaster T100 and similar wheels.

* Madcatz wheel - fixed an issue where the switch on the wheel to change between 270 to 900 degree mode stopped functioning.

Physics & AI
* Slowed down the AI opponents in the rain when using racing tyres, to make racing against them better balanced.
* Adjusted the AI tyre wear rate to better match the player’s tyre wear rate.
* Adjusted wear of Slicks and Rain tires to more realistic levels where needed. Typically GT/LMP/Formula cars will get slightly more than a full fuel load on soft or default slicks (depending on fuel load amounts).
* Adjusted the heating of slicks and rain tyres to more realistic levels.
* Adjusted tyre temperature sensitivity on several cars.
* Adjusted rain tyres to generally be more sensitive to overheating, and less efficient in the dry.
* Improvements to AI navigation to lessen collisions during cramped race starts, improve detection of other cars during cornering, and improve clean overtaking
* Improved the AI pitting logic during practice and qualifying so that the AI cars run more realistic stints before pitting.
* Reworked the AI’s fuelling logic during qualifying sessions where no refuelling is allowed, so that they don’t always fill up the fuel tanks and negatively impact their qualifying ability. The AI will now deliver far more competitive lap times during qualifying.
* Fixed an issue where the AI would set impossible lap times during races with pit stops.
* The AI will now pit as soon as possible when low on fuel to prevent them running out of fuel and retiring from the race.
* Reduced the effect of damage to the car’s cooling system when suffering aero damage. This prevents engines from overheating and blowing at an unrealistic rate.
* Fixed an issue that prevented bump starts from working properly on some cars. An example case – with gears and clutch set to manual, take an Ariel Atom out on Brands Hatch. At the first right hander, stall the car, ignition on, 2nd gear, roll down the hill up to about 15kph and drop the clutch. The car will now bump start. Exact conditions for a successful bump start will vary slightly by car.
* Fixed an issue where at times some AI drivers in a race would use much higher skill levels than the rest of the field.
* Fixed an issue that prevented the AI from pitting within the final 3 laps of a race
* Further tweaked the AI ability in wet races to more closely match the player car’s ability in the wet
* Improved the AI’s efficiency in pit timing when needing to change tyres due to weather conditions.

Pitting, tuning, setups
* Fixed an issue where wet tyres were fitted too long before the rain starts, causing excessive overheating and wear on the tyres.
* Fixed an issue where, when running low on fuel, the Pit Board would appear to tell the player to do a scheduled pit stop when the player did not schedule a pit stop.
* Fixed an issue where flat tyres were fitted to the car during a pit stop, by ensuring that the tyres are correctly inflated.
* Fixed an issue where the car’s bump-stop value decreased after leaving a race session and joining it again.
* Reworked the brake bias display information so that changing the values is more intuitive.

Tracks
* Performance optimisation pass done on: Brands Hatch layouts, Cadwell layouts, Oulton Park layouts, Bathurst, Azure circuit, and Zolder. This helps improve the overall smoothness when racing on these tracks with large grids of cars.
* Track cutting tolerances reduced on all tracks where it was too forgiving.
* Fixed an issue where a pit crew character would at times appear floating above the race track on various tracks.
* Silverstone Stowe – fixed render issues on some tyre stacks, and addressed an issue with cars driving through certain objects.
* Road America – fixed an issue where a line of grass line appeared in the air near a concrete barrier.
* Spa Francorchamps – fixed an issue where cars under AI control would bump into the pit wall when exiting the pit lane. Fixed an issue where the AI were running too wide over the exit curb at the Bus Stop Chicane.
* Brno – fixed an issue where cars would at times start in the same grid positions, fixed garage six to prevent the AI from getting stuck on the right side wall when exiting the garage spot, fixed an issue when running more than 20 cars in a race would cause the car in 21st to slide into the pits.
* Le Mans – fixed an issue that would at times cause the car to crash while in the pit lane, leading to a disqualification. Improved the AI race line for better speed, and improved the AI behaviour on curbs.
* Laguna Seca – improved the AI performance as they were running too slow in some sections.
* Imola – Improved the pit lane AI navigation, and fixed an issue with a section of the fence at the pit entrance that appear to float.
* Bathurst - fixed a render issue with shimmering edges in parts of the track.

Career

* Gumpert Apollo – fixed an issue with the livery sets that caused the livery selection to display wrong liveries.
* Aston Martin Vantage GT3 – tuned engine lifetime and brake cooling parameters for better accuracy.
* Lotus 98T – tweaked turbo to improve AI estimation of top speed.
* McLaren F1 GTR – modified the default setup and reduced front bump steer to improve straight line stability, fixed an issue to ensure that the car’s specific HUD motec display is used
* McLaren F1 - Fixed an issue that caused the car to use the wrong default tyre compound.
* Ford GT40 MK4 – Reworked in several areas to improve handling and match the real car closer - Bump stops settings exposed in setup with better tuned setup defaults, increased wrap around stiffness of the tire carcass, rebalanced base vs tear grip, rebalanced player vs AI rain performance against the AI.
* All Formula vehicles – Stop brake light reflections appearing on cars that don’t have brake lights.

General
