Definition of recommended system requirements
Recommended system requirements are the hardware and software specifications for optimal performance and user experience. These specifications are intended to ensure that the application runs smoothly and efficiently.
What to expect when using the recommended system requirements?
Fast simulation and styling.
Smooth navigation in the 3D window.
High quality real-time textures in all zoom levels.
High performance on multiple 3D windows in the 3D review workspace.
Definition of minimum system requirements
Minimum system requirements refer to the least set of hardware and software specifications necessary for VS to install and run. Meeting these requirements ensures that the application can operate at a basic level, though performance might not be optimal.
What to expect when using the minimum system requirements?
Slower simulation and styling.
Slower navigation in the 3D window on complex garments and outfits.
Reduced Real-time textures quality depending on zoom level.
Slower Ray-Trace renders.
Reduced performance on multiple 3D windows in the 3D review workspace.

Processor | Intel® Core™ i7 Processors / AMD® Ryzen 7 processors | Intel® Xeon Processor, 12 cores, min. 3.2 GHz or higher |
Memory (RAM) | DDR4 16GB | DDR4 32GB |
Graphic card For information about NVIDIA graphics cards, go here. | NVIDIA® GeForce GTX 960 / NVIDIA® Quadro P2200 | NVIDIA® RTX 3000 series / NVIDIA® Quadro RTX , RTX A series |
Storage | HDD 256GB | SSD minimum 512GB |
Screen | 1920x1080 60Hz | 2560x1440 60Hz |
3-button mouse (left-click, right-click, scroll wheel) | 3-button mouse (left-click, right-click, scroll wheel) | |
Operation system | Windows 10 64bit supported in the following versions: 2024.2.x (all builds) 2025.1.x (all builds) 2025.2.1 (Build 54551) | Windows 11 supported in the following versions: 2024.2.x (all builds) 2025.1.x (all builds) 2025.2.1 (Build 54551) |
GPU Memory: VStitcher and Lotta (version 2022.1 and later), use Unreal Engine as the default 3D display engine. For best 3D performance and navigation with Unreal Engine, check your computer's GPU memory settings (VRAM). The minimum is 4GB VRAM; however it is recommended to use 8GB or higher. Using 8GB will provide a smoother workflow and prevent blurry textures, especially when zooming in. To locate the VRAM on your machine, see Locating the VRAM information on your Windows machine.
For Real time ray trace use NVIDIA® RTX 3000 series Graphic Card. See Graphics Card Drivers and Settings for further recommendations.
It is not recommended for users to use VStitcher or Lotta on a virtual machine, as performance is significantly reduced. Always install the application on each user's actual physical laptop or workstation.
VStitcher and Lotta System Requirements - Mac
The following table displays system requirements for Mac users.
Component | Minimum | Recommended |
Processor (CPU) | Intel® i7 with 8 cores | Apple Silicon M1 (all types) or higher |
Memory (RAM) | DDR4 16GB | DDR4 32GB |
Graphic card (GPU) | AMD Radeon™ R9 M375, 4GB | Apple M1 GPU (all types) or higher, 16GB or higher |
Storage | HDD 256GB | SSD minimum 512GB |
Screen | 1920x1080 60Hz | 2560x1440 60Hz |
Operation system | MacOS 15.4 Sequoia supported in the following versions and builds: 2024.2.4 (Build 54350) 2025.1.2 (build 54351) 2025.1.3 (build 54410) 2025.2.1 (Build 54551) | MacOS 26.1 Tahoe is supported in the following versions and builds: 2024.2.4 (Build 54350) 2025.1.2 (build 54351) 2025.1.3 (build 54410) 2025.2.1 (Build 54551) |
