Павлов В.Р. – How to Fix Oculus Link Issues

This guide provides step-by-step instructions for identifying and resolving various issues related to Oculus Link. It also offers presets specifically designed for minimum-spec systems.

Prerequisites for Oculus Link

Oculus Link differs from other PCVR headsets as it doesn’t directly transmit a raw video stream to your headset. Вместо, it involves a compression process that is later decompressed on your headset. To ensure smooth functioning of this process, you’ll need adequate hardware.

• Minimum requirements for Pavlov VR: 3060Ti/6600XT or an equivalent previous generation GPU, along with a modern 6-core CPU running at 4GHz or higher.
• Your PC should have a USB3 or USB-C port.
• You’ll also need a USB3 cable.

ПРИМЕЧАНИЕ: Some USB-C to USB-C cables may only support USB2. Чтобы убедиться в этом, you can test the cable in the Oculus software’s “Устройства” вкладка.

It’s important to understand that Pavlov, unlike most popular PCVR shooters, does not compromise its in-game visuals and graphics to match the quality of its standalone Quest version. Поэтому, it is expected that the game’s performance may not be on par with titles that do make such compromises. Как результат, it might be necessary to lower the graphical settings in order to achieve comparable performance to other games.

Поиск неисправностей

Achieving optimal performance with Oculus Link relies on maintaining a careful balance between resolution, bitrate, and refresh rate. If any of these settings are set too high, it can strain the encoding process and result in issues like bounciness, choppiness, артефакты, or a combination of these problems. In the following section, we will address these issues and provide troubleshooting steps.

For certain troubleshooting steps, you may need to utilize the Oculus debug tool, which can be found at “Program Files/Oculus/Support/oculus-diagnostics/OculusDebugTool.exe”.

Artifacting, Tearing, and/or Bounciness

Artifacting occurs when the Link process becomes overloaded and is unable to generate high-quality frames. This typically indicates that the bitrate, разрешение, or refresh rate is set too high. Чтобы решить эту проблему, следуйте инструкциям ниже:

• Давать возможность “Encode Dynamic Bitrate”: By enabling this option, you allow Oculus Link to manage the bitrate automatically. This means that Link will dynamically adjust the bitrate to provide you with the best possible picture quality without causing any overload.

• If you are still experiencing artifacting issues, it may be necessary to lower your resolution or refresh rate settings, as they might be currently set too high. You can adjust these settings in the “Устройства” tab of the Oculus settings. By reducing the resolution or refresh rate, you can alleviate the strain on the Link process and potentially resolve the artifacting problem.

Low Framerate and/or Frame Drops

If you are encountering low framerate or frame drops and you are certain that there are no artifacts, tearing, or bounciness in your visuals, it will be necessary to lower your graphics settings. Consider following these steps:

• Adjust the resolution in the Oculus settings by reducing it. In the legacy branch, you can use the resolution slider for this purpose.
• Lower the in-game settings such as Anti-aliasing, Эффекты, or Textures. By reducing these settings, you can alleviate the strain on your system and potentially improve the framerate and overall performance.

Additional Troubleshooting Steps

Here are troubleshooting steps for edge cases and persistent problems:

Jelly-like effect and slight bounciness

• Follow the troubleshooting steps mentioned in the previous section.
• Запрещать (ПК) Asynchronous Spacewarp and Mobile ASW. These features can sometimes contribute to the jelly-like effect and slight bounciness in the visuals.

Link crashing

• Ensure that your GPU drivers are up to date. If your GPU vendor specifically mentions issues with Oculus Link, consider rolling back to the previous working version of the drivers.
• Make sure that your Windows operating system is up to date.
• Disable Windows Game mode, as it can sometimes interfere with the stability of Oculus Link.

Floatiness/Bounciness

• Reduce the bitrate setting. Lowering the bitrate can help mitigate floatiness and bounciness in the visuals.
• Utilize dynamic bitrate and ensure that you haven’t set the Max Dynamic Bitrate too high. A recommended value for the average modern gaming hardware is 200. Adjusting the dynamic bitrate can help achieve a more stable and smoother experience.

If you’re still unable to resolve your issues despite following the troubleshooting steps mentioned, I recommend joining the Oculus Discord community. By joining the Discord server, you can seek additional assistance from knowledgeable users who may be able to provide further guidance and support in troubleshooting your specific problem. The community members are often helpful and experienced in addressing various Oculus-related issues, and they may be able to offer personalized solutions or suggestions to help you overcome any persistent problems you’re facing.

Предустановка

Here are some presets optimized for systems that meet Pavlov’s recommended specifications (3060Ti/6600XT or previous generation equivalent and a modern 6-core 4GHz+ CPU). Feel free to adjust these settings if you have a more powerful system.

Производительность:

• Частота обновления: 120Гц
• Разрешение: 3104×1584
• Encode Bitrate: 0
• Dynamic Bitrate: Включено
• Dynamic Bitrate Max: 200
• This preset offers a balanced configuration with reliable performance and good visuals.

Примечание: The following presets are based on a system with a 16GB i5 10600k and RX6600XT. Adjustments can be made depending on your specific hardware.

Less Balanced, More Visual Clarity:

• Частота обновления: 90Гц
• Разрешение: 3616×1840
• Encode Bitrate: 0
• Dynamic Bitrate: Включено
• Dynamic Bitrate Max: 200

This preset prioritizes visual clarity over balance, providing improved visuals at the expense of some performance.

Visual Fidelity:

• Частота обновления: 90Гц
• Разрешение: 3648×1856
• Encode Bitrate: 0
• Dynamic Bitrate: Включено
• Dynamic Bitrate Max: 300

This preset aims for higher visual fidelity by increasing the resolution, maintaining a 90Hz refresh rate, and enabling a slightly higher dynamic bitrate.

Visual Fidelity (Альтернатива):

• Частота обновления: 80Гц
• Разрешение: 3936×1984
• Encode Bitrate: 0
• Dynamic Bitrate: Включено
• Dynamic Bitrate Max: 200-300

This preset further enhances visual fidelity by increasing the resolution to 3936×1984, at the cost of a lower refresh rate (80Гц).

Помнить, these presets can be adjusted based on your system’s capabilities and personal preferences.

Self-Diagnosing Issues

To identify issues on your own, вы можете выполнить следующие действия:

1. Enable the “Производительность” HUD in the “HUDs” section of the Oculus Debug Tool.
2. Put on your headset and launch a Pavlov game.

• If you notice that the “Compositor frames dropped” count is flashing red and increasing, it indicates that your Link process is overloaded. В этом случае, you will need to reduce either the bitrate, разрешение, or refresh rate settings.
• If you observe that the “Application frames dropped” count is flashing red and rising, it suggests that Pavlov is being limited by your GPU’s performance. Чтобы решить эту проблему, you should lower the in-game graphical settings or decrease the resolution.
• The “Performance headroom” metric is a useful indicator of the additional performance available to render more demanding scenes. If you find that your headroom is very low in a less intensive scene, such as an offline lobby, it is advisable to consider reducing your graphical settings or resolution.
• Наоборот, if your headroom is high (выше 50%), you have some leeway to increase the resolution or graphical settings. Однако, if you choose to raise the resolution, be aware that despite your GPU’s capabilities, pushing it to its limit can potentially strain Oculus Link and lead to problems.

By following these steps and monitoring the performance indicators, you can gain insights into potential issues and make informed adjustments to optimize your Oculus Link experience.
