public static class GpuSpoof

Picks a plausible WebGL vendor/renderer pair of the same GPU architecture as the machine's card, from the public PCI ID list.

Methods#

BuildGpuJson#

public static string BuildGpuJson(string pciIdsUrl = "https://pci-ids.ucw.cz/v2.2/pci.ids")

source

Downloads the PCI ID list and groups the GPU models of NVIDIA, AMD and Intel by vendor and architecture (only GeForce/Quadro/Tesla/RTX, Radeon/Navi/Vega/Polaris and HD Graphics/UHD/Iris/Xe/Arc entries).

Returns: JSON [{ Vendor, Archs: [{ Arch, Models: [{ DeviceId, Name, Chip }] }] }].

DetectCurrentArch#

public static string DetectCurrentArch(string gpuJson, string cardName = null)

source

Architecture of the card in gpuJson: the first model of the card's vendor whose name contains the card name or is contained in it.

Returns: Architecture name, or an empty string.

EnsureGpuJson#

public static string EnsureGpuJson(string path)

source

Reads the GPU JSON from path; when the file does not exist, builds it with BuildGpuJson and saves it (one builder at a time).

GetCurrentCardName#

public static string GetCurrentCardName()

source

Full name of the machine's video card from WMI (the second card when there are several); empty on error.

GetCurrentVendor#

public static string GetCurrentVendor()

source

Vendor of the machine's video card from WMI Win32_VideoController; with several cards the second one is used.

Returns: NVIDIA, AMD, Intel, the first word of another name, or an empty string.

LoadGpuJson#

public static string LoadGpuJson(string path)

source

Reads the GPU JSON from a file.

RandomAngleString#

public static string[] RandomAngleString(string gpuJson, string cardName = null)

source

Random model of the same vendor and architecture as the card, formatted as Chrome's ANGLE strings.

Returns: ["Google Inc. (NVIDIA)", "ANGLE (NVIDIA, NVIDIA {model} (0x0000XXXX) Direct3D11 vs_5_0 ps_5_0, D3D11)"]; two empty strings when the architecture is unknown.

SaveGpuJson#

public static void SaveGpuJson(string json, string path)

source

Writes the GPU JSON to a file (UTF-8).
