    The legendary Circuit de la Sarthe will be made available to purchase in iRacing.com as part of the substantial Season 4 update release due next week.

    Not content with just releasing the legendary circuit, Season 4 update brings a raft of changes to the sim with several vehicles benefitting from a variety of fixes and enhancements. The usual front end updates make it into season 4, with revised menus and updated documentation sitting alongside further development of the dynamic track technology. The latest release will include updates to improve the calculations used to conduct heat from tyres onto the track, aiming to "increase the realism of heat mapping and make rubber have a bit more of an impact on your race."

    Other highlights from the season 4 build include real time reflections on vehicle windshields and improvements to the night conditions in game with the new Dynamic Night Shadow Maps system.

    Check out the iRacing.com Le Mans Release Trailer:


    The full Season 4 change log can be viewed below:

    Website

    • The Live Broadcast Banner that slides into view after a short delay whenever a broadcast is available has been moved to the fixed footer of the website. It also no longer pushes the webpage content when it slides into view.
    • The “About” information related to the different Series Sessions (ie: Practice, Qualify, Race), previously seen at the bottom of each session block for the series, has been moved into a mouse-over panel, titled “Tell Me More,” below each session title. This information has also been updated and expanded.
    • On the Stats pages, tooltips have been added to show the “About” information for each session type.
    • Fixed an error with the Stats page due to special characters not being displayed.
    • The Past Seasons page has been restored, and scoped down to only display the past two years.
    • The Sporting Code documents have been updated.
    • Descriptions for the session on each series’ session page have been updated.
    • When hosting a Session, the Practice Session Time now defaults to the same value used previously.
    • The “Options” toolbar dropdown in the Official Race Guide will now always be displayed.
    • The iRacing Merch page has been re-added.
    • A handful of loading indicators have been added to the League Manager menus and several of the league processes should now load faster.
    • The UI for the Car and Track pages has been updated.
    • Embedded YouTube videos on the forums are now 640×360, and can now be viewed in full-screen mode.
    • A post-race quality survey now appears whenever you exit a session of any type.
    • Steam users are now prompted to create an account password for members.iracing.com for additional security and stability.
    • Minor text fixes.
    Connection
    • The Q-Bar on the frame rate/connection status meter area now has two side-by-side meters. The original value is in the left-hand bar, and shows the amount of packet loss from the race server to the simulation. The new right-hand bar (which grows from right to left) shows the amount of packet loss from the simulation to the race server. Note that the data for this right-hand bar is sent from the server to the simulation, so if there is a sudden loss of all packets sent by the server to the simulation, the value in this bar will not update. As before, each bar becomes full at 50% packet loss, though each is now about half the width of the original Q meter.
    Sessions
    • Fixed an issue where a team member in a driver-swap session could be incorrectly marked as Unofficial if it happened that none of the team’s members were registered for the session as it was launched.
    • Fixed an issue where suspended members were being allowed to join multiplayer sessions.
    Time Trial
    • Fixed an issue that was causing some Time Trial sessions to be run with the “time of day” set to something other than the default of “afternoon”.
    Garage
    • When you use the “Share a Car Setup” capability on the Garage screen inside the Sim, the name of the setup is now also sent and will be displayed to the recipient(s).
    Dynamic Track
    • Increased the effective starting usage level, which controls the amount of rubber on the track, for sessions that have a short Practice and an attached Qualifying prior to a Race.
    • Improved the calculations used to conduct heat from the tire into the track, and updated the conduction and convection model for the track surface. This results in lower starting track temperatures, but a significantly more dynamic range when cars interact with the track.
    • The tearing of rubber from the tires versus from the track has been adjusted so that when a tire is not sliding, it is more inclined to pick up track rubber. Also, the calculations for determining the thickness of the track rubber under the contact patch and the rate at which the track will accept rubber have each been improved. The combination of these changes will make the track rubber build up about three times as fast, and in general be more dynamic.
    • The Dynamic Track system now assumes there is some residual starting dust on the track even before any simulated running of cars or cleaning for a session is performed. The amount of starting dust is related to how must dirt and gravel is around that track, such that a track like Mazda Raceway Laguna Seca is more prone to being dusty than a track like Talladega Superspeedway.
    • Dust will now be picked up and thrown due to air displacement near moving vehicles.
    Mirrors
    • With the Virtual Mirror option enabled, a hotkey (Alt+M) has been added to show/hide the virtual mirror while driving.
    Driver
    • A new driver character model has been fully implemented into all vehicles.
    • The new driver has been shifted into a more accurate position in some vehicles than the previous driver.
    • Due to the new driver model, the driver camera position in some cars to be adjusted slightly for a better perspective.
    • All vehicle seat belts now change color to match driver selections.
    Pit
    • The pit box characters behind the wall and the lollipop guy are now using a new character model.
    Rendering
    • All cars have had their windshields updated to use a new shader which provides realistic reflections.
    • Driver, pit crew, and pit boxes for all cars have been converted to use PBR shaders.
    DirectX 9
    • Our support for using DirectX 9 as the graphics system used by the simulation is winding down. If you are currently using DX9, your selection will be changed to DX11 one time upon installing this build. If you run into issues using DX11, you should work with our support team at http://members.iracing.com/jforum/posts/list/3344813.page
    • The ability to clear fuel, windshield, and fast repair pit commands have been added using the IRSDK api.
    • Data will now only be pushed if a device is connected.
    Oculus Rift
    • The bounding box on the driving camera has been set to 0.10 meters (4 inches) in the vertical direction, and to 0.25 meters (10 inches) in all other directions to give users a little more room to move around.
    • The Oculus Rift mirror window display has been altered to show the source render for the left eye, rather than the post-distorted images of both eyes.
    • Anti-aliasing has been enabled.
    • The health and safety warning has been removed from the loading screen.
    OpenVR / HTC Vive
    • OpenVR / HTC Vive support has been enabledThe following OpenVR settings have been added to the “RendererDX11.ini” file:– – [OpenVR] – – OpenVREnabled=1 ; Enable OpenVR Support.– – ResolutionScalePct=150 ; (50% to 300%): 125%=1.25, over 100% may hurt performance! – – AutoSelect=0 ; Use OpenVR without prompting (NOTE: Oculus will have priority if enabled) – – AutoCenter=0 ; Re-center the HMD pose when health/safety warning disappears. – – UIScreenSize=130 ; (cm) 3D UI screen width. – – UIScreenDistance=70 ; (cm) 3D UI screen distance.
    • NOTE: The resolution scale percentage setting (“ResolutionScalePct”) is similar but not equivalent to the Oculus Rift setting: “PixelsPerDisplayPixel”. For OpenVR, you are directly scaling the off-screen render target, while for the Rift you are scaling the pixel density in the center of the image – so the values are not directly comparable with each other.
    • Full-screen anti-aliasing for headsets operating via OpenVR (HTC Vive) has been enabled.

  2. Err, not released until next week. The patch notes even say its got to be run by the ACO once more before release. The season update also isn't out, since we're still in the season, so that won't be out until next week either.

    I was all excited when I viewed this thread...so I logged into iRacing just to make sure...I can not purchase LeMans just yet.
     
  7. the two nice bits:
    "The Patrouille de France will now be performing fly-overs at Le Mans."

    and:

    "iRacing Surprise
    - A previously unannounced special addition will be brought to iRacing during the first week of 2016 Season 4!
    - - Be sure to visit http://www.iracing.com at 1:00PM EDT (17:00 GMT) for a special presentation on Tuesday, September 13th, 2016!"

    Since I will be at home at that time, I will actually put that into my scheduler and see what it is, maybe the first DIRT track or a LeMans specific car, or quite possibly something less spectecular, like Bram's famous Father Christmas Mod in the EyeOpener game. any other bets?

  8. Still no new in-game UI and transfer of most of the functionality from the web site into the game.

    Can I assume the weather still affects the tire grip way too much, even after the adjustments they mentioned for dynamic track system? I guess so.

    So from my point of view, another patch that doesn't solve the major problem with the sim. The UI is not much of an issue, it's just something that would be finally nice to have, but the weather affecting the grip the way it is now, it is.

    I'm disappointed. Again.

    Looking forward to La Sarthe, dynamic tracks and dirt. I hope they can include the newer IndyCars (with Chevy and Honda aero packages) soon as well.

    It's back ladies and La Sarthe is in my hands now!
     
  13. don't think dirt will already be in there. What I guess atm is that the big surprise will be a new, tablet friendly user interface. downloading 1.75G worth of updates atm. Off to do some housework in the meantime, kitchen sink here I come!

  15. the shop seems to be broken atm, you can put stuff into the cart but you can neither access the cart nor your account showing how much cash you have at the ready. :( darn, hope my lemans circuit hasn't gotten stale overnight, put it into cart at about 22.00, still lingering there I guess 16 hours later :( :( .

    I read on the forum that that the handling might be more believable and predictable, so you can catch slides better. Can somebody confirm this? That’s one big minus I have with Iracing, every other sim handles better imo (AC, Automobilista, Rfactor 2).
     
  17. didn't notice any serious change, but then again i only played the ford gt3 on lemans, not much cause for sliding there. it did feel a bit more soft overall, but again this may have just been the track ...

    Eckhart, the Ford GT is GT2 on LeMans, not GT3.
     
  19. ah, never noticed, lol.
    iRacing changed all installs to 64bit status and also had a benchmark tool going over my graphics settings, now the game looks dreadful. SWill have to do some dialling in tonight. Anyone got any clue why after the benchmark test my i7 was set to "use one cpg" rather than using 2 or 4?

    edit: mixed up cpg's and cpu's, sorry, my bad, no clue about technology.

    Yesterday I fired up Iracing for the first time in several months just to check out week 13 and the new laserscanned Le Mans. They have the 24mins of Le Mans right now, so that’s about 7 laps. I choose to drive the HPD and took part in two races, which were quite nice.
