System requirements for CLO software

Apple macOS 10.14 (Mojave), 10.15 (Catalina), 11.2 (Big Sur)
Processor AMD® or Intel® 64-bit multi-core processor 2)

1) Strongly recommend to complete Windows update and patches: Microsoft guide

2) AMD 2nd-Gen Ryzen 5 or Intel 6th-Gen i7 or higher

3) CLO utilizes Nvidia CUDA acceleration technology for CLO GPU-Simulation and Rendering. So computers with only Intel Graphics or AMD GPU do not benefit from hardware acceleration that speeds up CLO simulation and rendering. In a non-Nvidia GPU equipped computer, calculations necessary for CLO simulation and rendering are performed on the CPU, and the visual quality of these results is the same.

Not supported
