Hardware Infos — Functions

This page lists every Blueprint function available in the Hardware Infos plugin.

How These Functions Work

All getter functions share the same behaviour:

• Blueprint Pure — they only read cached data, never modify any state. Safe to call as many times as needed.
• Blueprint Callable — accessible directly in any Blueprint graph.
• Category HardwareInfos — find them quickly by searching Hardware in the Blueprint palette.

Because hardware queries can be expensive, avoid calling getAllDataHardware every frame. Call it once on Begin Play and store the result in a variable. For live RAM and VRAM updates, use refreshDynamicData on a timer instead.

Initialisation

getAllDataHardware

Collects all hardware data (CPU, GPU, RAM, Screen) and stores it in an internal cache. Call this once at startup — for example from Begin Play or Game Instance Init.

• Returns: nothing

static void getAllDataHardware();

refreshDynamicData

Updates only the values that change over time: RAM usage and VRAM usage. All other data (CPU model, GPU name, total VRAM...) stays cached from the last getAllDataHardware call.

• Returns: nothing

static void refreshDynamicData();

Call this every few seconds via a Timer by Event to keep RAM and VRAM usage current without the overhead of a full hardware scan.

Hardware Information

getHardwareData

Returns a complete hardware summary in a single call — CPU, GPU, RAM, and Screen combined.

• Returns: FHardwareData

static FHardwareData getHardwareData();

Use this when you need everything at once, for example when writing a full system report to a log on launch.

getCpuData

Returns detailed information about the CPU.

• Returns: FS_CPU_Infos

static FS_CPU_Infos getCpuData();

Supported CPU families:

• AMD Ryzen 5 / 7 / 9 (all generations)
• Intel Core i3 / i5 / i7 / i9 (classic naming — 10th gen and up)
• Intel Core Ultra 5 / 7 / 9 (200 series)

getGPUData

Returns detailed information about the GPU, including VRAM usage and driver version.

• Returns: FS_GPU_Infos

static FS_GPU_Infos getGPUData();

VRAM data is retrieved via DXGI (IDXGIAdapter3) — works on NVIDIA, AMD, and Intel GPUs without any third-party SDK.

Supported GPU families:

• NVIDIA GeForce GTX / RTX (all series)
• AMD Radeon RX / Pro (all series)
• Intel Arc A-series / B-series

getRAMData

Returns information about system RAM — total, used, and free — in both MB and GB, plus virtual memory stats.

• Returns: FS_RAM_Infos

static FS_RAM_Infos getRAMData();

For live updates, call refreshDynamicData on a timer rather than calling getRAMData every frame.

Display

getScreenResolution

Returns the player's current screen resolution, refresh rate, and aspect ratio. This function refreshes its data on every call.

• Returns: FS_ScreenResolution

static FS_ScreenResolution getScreenResolution();

getCurrentFPSLimit

Returns the FPS cap currently set via the t.MaxFPS console variable.

• Returns: int — 0 typically means uncapped

static int32 getCurrentFPSLimit();

isVSyncEnabled

Returns whether VSync is currently active (r.VSync).

• Returns: bool — true if VSync is on, false if off

static bool isVSyncEnabled();

Performance Monitoring

getFps

Returns the current framerate calculated from delta time. Connect the Delta Seconds output of your Event Tick node.

• Input: float DeltaSeconds
• Returns: int32

static int32 getFps(float DeltaSeconds);

getFpsApp

Returns the current framerate using FApp::GetDeltaTime() — no input required. Useful when you want FPS without hooking into Event Tick.

• Returns: int32

static int32 getFpsApp();

Prefer this version for simplicity. Call it from a Timer by Event every second to display FPS in a HUD without using Tick.
