IMPORTANT: Currently, the Character Creator tool is only supported in DirectX 11. Also, please make sure that you have a compatible graphics card. For more information on Character Creator requirements go HERE and scroll to the bottom. 

Optimize performance by switching between system memory and graphics card memory:

• If you are running a video card with less than 2 gigabytes of video memory on an independent graphics card, then it is recommended to have the program use system memory instead. 
• To use system memory, go to Character Creator > Edit Menu / Preference. Scroll to the bottom and un-check the “Maximize video memory usage” option. 
• If you have sufficient system memory (>8GB), then you may try to load several substances at once by editing multiple outfits without having to reload each. Do this by un-checking “Load one Substance a time” option.
• Restart the program for the settings to take effect.
