Development Environment Requirements

Development Computer Hardware Requirements

The Unity development engine and 3DGS rendering are heavy resource consumers and place relatively high demands on CPU, GPU and memory. Low-performance platforms may affect smoothness or even fail to run. Memory and video memory are usually the performance bottleneck. The recommended development computer hardware configuration is as follows.

💻 Recommended Development Hardware (cost-performance route)

Component	Recommended Configuration (cost-performance route)	AMD Equivalent
GPU	NVIDIA RTX 30 series (12 GB), or at least RTX 3060 Ti (8 GB)	AMD Radeon RX 6900 XT / 6950 XT (16 GB)
CPU	Intel Core i7-12700K / 12700 (12 cores, 20 threads)	AMD Ryzen 7 5800X3D / 7700X (8 cores, 16 threads)
RAM	64 GB DDR4 (3200 MHz / 3600 MHz)	64 GB DDR4 / DDR5
Storage	2 TB NVMe M.2 SSD (PCIe 4.0, read > 5000 MB/s)	Same as left

Video memory: prioritize 12 GB of video memory; machines with 6 GB / 8 GB may cause the Unity Editor to crash due to insufficient video memory (Out of VRAM) at runtime. Some AMD GPU models may have compatibility issues.

Memory: do not skimp; 64 GB is recommended, with at least 32 GB required. When memory is insufficient, the system tends to use virtual memory, causing stuttering or even system-level freezes.

Monitor: a monitor with a resolution of 1920×1080 or higher is recommended.

USB: keep at least one USB port available for copying data from hardware devices.

OS Adaptation and Optimization

The LCC Unity SDK fully supports all features on the three major desktop platforms — Windows, macOS and Ubuntu — but the three differ greatly in graphics API, video memory model and driver dependencies, so hardware selection and optimization strategies must be handled separately. The cost-performance configuration table above is based on Windows + NVIDIA; refer to the table below when migrating to the other two platforms.

OS	Version Requirement	Graphics API and GPU	Adaptation and Optimization Suggestions
Windows	Windows 10 / 11 (x64)	DirectX 11 / 12 with native Compute Shader support; NVIDIA GPUs are preferred	The most complete and most thoroughly validated platform; the cost-performance configuration table above applies directly.
macOS	macOS 12 (Monterey) and later	Metal, with Compute Shader running through the Metal backend; Apple Silicon (M-series) recommended, Intel + AMD discrete GPUs also work	Apple Silicon uses unified memory, where video memory and system memory share the same physical memory, so you cannot just look at the total memory; 64 GB of unified memory is recommended as a starting point to leave enough video memory share for rendering. Uses the Metal universal path.
Ubuntu	Ubuntu 20.04 and later	Vulkan, with Compute Shader running through the Vulkan backend; NVIDIA GPUs are preferred	GPU selection is the same as Windows (RTX 3090 24 GB preferred). You must install the official NVIDIA proprietary driver (avoid the open-source nouveau driver), otherwise Compute Shader will not work properly; keep the driver relatively up-to-date for Vulkan feature compatibility.

Unity Version Requirements

The LCC Unity SDK provides separate SDK installation packages for different Unity versions. Download the corresponding package according to the Unity version you are using. The following versions have passed complete testing:

Unity Version	Supported Render Pipelines	Status
Unity 2022.3.62f3 (2022 LTS)	Built-in, URP	✅ Tested
Unity 6000.0.69f1 (Unity 6 LTS)	URP	✅ Tested
Unity 6000.5.9f1 (Unity 6 LTS)	URP	✅ Tested

Other runtime environment requirements:

Item	Requirement
GPU	Supports Shader Model 5.0 (Compute Shader)
OS	Windows 10+ (x64) / macOS 12+ / Ubuntu 20.04+ (see platform adaptation above for details)
.NET	.NET Standard 2.1 / C# 9.0
