    How to improve the performance of the Oculus Rift
    When using the viewer the Oculus Home program automatically starts without which the viewer will not work, but this program uses up to 20% of the PC resources (especially the processor). Being able to use Oculus without starting Oculus Home therefore means having more resources on the CPU to be used for the game, ie greater fluidity and responsiveness.
    How to do?
    open Oculus Home, go to the gear symbol, then setting and general, and check if at the bottom of the page the Rift and Touch Safety tick is off (if it is active, deactivate it), then close Home
    Right click on the Oculus icon on the desktop
    in the menu that appears click on PROPERTY
    in the window click on COMPATIBILITY
    check the Run the program in compatibility mode for Windows 8
    then at the bottom put the check on Run this program as an administrator
    you will notice that wearing the Oculus will no longer start the Home program
    open the game, choose the track and car and go forward: worn Oculus will be all black screen, but it is normal, but stay still for positioning
    after the loading you will be on the track with a gain of up to 20% in performance, greater fluidity especially in the movements of the garment.

    Let's start with the graphic settings of race set-up, to get a better visual quality in our Oculus.

    Settings
    Resolution: 1920x1080 (Only affects the size of the virtual HUD, not the actual game rendering resolution)
    Fullscreen Rendering: Enabled (improves performance and means that your mouse is always usable if your screen is higher resolution than set above)
    Rendering Mode: Oculus Rift or OpenVR
    Crepuscular rays: Off (bugged in VR - see known issues)
    Fast Approximate Anti-Aliasing: Off (blurry)
    Lock onboard camera to Horizon: Experiment to see what you prefer, can affect motion sickness, sense of elevation changes. I recommend RHM as it can give the best of both (see recommended mods section)
    G-force effects*: 0.4x, 0.1x, 0.4x
    Camera shake at high speed*: 0.2x
    Display downshift protection notification: Off (immersion)
    *These are down to personal preference. G-force and camera shake may contribute to motion sickness, and require the following parameter to be edited for them to be active in VR:
    assettocorsa\system\cfg\assetto_corsa.ini
    ENABLE_CAMERA_SHAKE=1


    Pixel Density (PPD, SS)
    Improves image quality, very demanding. 1.0 is default, increase in 0.1 increments. 1.4 seems a sweet spot. (Personally I pushed up to 2, but you have to keep an eye on the pressings of your PC)
    Oculus: Set in Documents/Assetto Corsa/cfg/oculus.ini (or in Content Manager)
    OpenVR: Set in OpenVR app in game, where you can also adjust IPD in Vive

    ASW/Asynchronous Reprojection
    Not a setting as such, but an important consideration, allows the game to be rendered at 45fps instead of 90fps and still feel fluid.

    Positive:

    • You can increase graphics settings with the additional GPU headroom
    Negative:
    • Will introduce some artifacts but for games like AC they are not too bad.
    • Some users find it less comfortable
    In general, it is allowed by default, so if you are not achieving 90fps the game will fall back to 45 and use this technology to provide a smooth experience. I am using it as it allows me to run PP and 1.4 PPD on a GTX 970.
    Oculus: Oculus TrayTool lets you define profiles so that you can force ASW on or off per game, I find this useful.

    Audio Device Auto Select
    Oculus: Set AUTOSELECT_RIFT_AUDIO_DEVICE=1 in Documents/Assetto Corsa/cfg/oculus.ini so that audio always goes to the Oculus instead of your windows default
    OpenVR: try Audio app in game

    Controller bindings
    Reset View: CTRL+SPACE (or bind ‘Look Left’ and ‘Look Right’ and press them together, however this is a waste of a button)
    Hide/Show Apps: CTRL+H (or CTRL+U to cycle through "virtual desktops")

    Recommended Mods
    Natural Graphics Mod If you run PP On, provides much more believable visuals and saves ~10fps fps over the default filter. If you run PP Off, you should still benefit from the adjusted weather files which should have a more consistent brightness and balance. I see some people using gbW in VR but it was way too contrasty for me in Oculus. I will provide a filter that should go nicely with the gbW weathers next time I update my graphics mod.

    Real Head Motion Allows you to have a mix of locked to horizon and car and filter bumps.
    My settings keep the car locked to horizon up to 10 degrees of pitch which gives good experience through normal and extreme (monza banking, eau rouge) situations:

    Top/Center Flags for VR By default the flags are impossible to notice because they are in the top left corner of your virtual HUD which you never would be looking at.

    Real display damage by Luc1gnol0 Much less intrusive than the default UI.

    Other tweaks
    Toggle Overlay Learderboard: F9 (when in a race)

    .ini Tweaks
    The Tweaks below will remove some of the persistent elements and low-importance server messages from your view so that you can have a fully immersive experience. You can display all of this information via apps which you can show/hide while driving.

    assettocorsa\system\cfg\messages.ini
    SERVER_PLAYER_JOINED=0
    SERVER_PLAYER_DISCONNECTED=0
    SERVER_KICKED_MSG=0
    assettocorsa\system\cfg\session_info.ini
    PRATICE_VISIBLE=0
    QUALIFY_VISIBLE=0
    RACE_VISIBLE=0

    Optimised Camera Position for all cars
    This is what the files in the download are for. Low importance, just a method of ensuring your view is at a consistent distance to the driver model for all cars. The files included in the download go in: \Documents\Assetto Corsa\cfg\cars
    and simply give the result of having gone through every single car and pressing "Auto-Pos" in the onboard settings app for every car, with some offset applied to move the view backwards and up slightly, hopefully your shoulders will line up much better with these files.

    Tried the Oculus home thing but doesnt work unless I'm doing it wrong. I use to be able to run AC with OUT Oculus home running by just running it as administrator. After Oculucs update it wont let me run it anymore unless Home is running.

    Recent Oculus updates introduced the new Home and the old trick no longer works, which is a pity as the new H0me dash is even more resource intensive than the original was.

    Would "Lock onboard camera to Horizon" stop me from having to recenter my hmd every now and then on track.

    I have my sensor on a mount on my sim and its getting quite annoying having to recenter it all the time?

    Thank you very much, I have an OCULUS RIFT CV1, and then I feel very good after using the settings you gave.

    Then I have a question and I would like to ask you for your help. When playing in the AC, there will be a ranking bar at the bottom of the screen. I don't know how to close the ranking bar, because in VR mode, this ranking bar still exists, and Blocked the steering wheel.

    Can anyone tell me how to set up to remove this ranking bar?
