Overview

What it does

A plugin that reads the CPU, cache, memory, graphics hardware and benchmark scores of the machine your game runs on, so you can scale features to fit. Maintained by DryreL for new Unreal Engine versions.

How it works

From zero to working

DetectCall the detect functions at startup or on a loading screen.
ComparePerformance indexes use 100 as an average good CPU or GPU: lower is slower, higher is faster.
ScalePick quality, effects and resolution to match the machine in front of you.

Features

Built to just work

CPU detectionQuery the processor's capabilities from C++ or Blueprint.
Cache and memoryRead cache and memory information of the machine.
RHI wrapperAsk the render hardware interface what the GPU supports.
SynthBenchmarkWraps Unreal's synthetic benchmark so you can pick quality settings from real scores.
Blueprint readyEvery detect function is available as a Blueprint node.
Kept currentOriginally released by Intel. DryreL maintains it so it keeps working with new Unreal Engine versions; no new features are planned.

Reference

Blueprint functions

Group	Function	Returns
CPU	IsIntelCPU	True on an Intel CPU
CPU	GetNumLogicalCores / GetNumPhysicalCores	Core counts
CPU	GetCoreFrequency / GetMaxBaseFrequency	Current and maximum frequency
CPU	GetCorePercMaxFrequency	Percent of maximum frequency in use
CPU	GetFullProcessorName / GetProcessorName	Long and short processor name
Memory	GetUsablePhysMemoryGB	Usable physical memory in GB
Memory	GetComittedMemoryMB / GetAvailableMemoryMB	Committed and available memory in MB
GPU	IsRHIIntel / IsRHINVIDIA / IsRHIAMD	True for that GPU vendor
GPU	RHIVendorName	Vendor name of the GPU
Benchmark	ComputeCPUPerfIndex / ComputeGPUPerfIndex	100 = average good, below is slower, above is faster

Good to know: The first call of each benchmark function runs the benchmark and is cached afterwards. Call both during startup or a loading screen.

Get started

Install and use

Install

1. Clone or download the repository.
2. Open Plugins/CapabilityDetect/Source/ThirdParty/CapabilityDetectLibrary/CapabilityDetectLibrary.sln
   and build it as Release x64.
3. Right-click the .uproject, choose "Generate Visual Studio project files", then build
   as Development Editor x64.
4. In the editor open Edit, Plugins and confirm Capability Detect is enabled.
