AVX instructions
Shader level 6

For the best experience, your PC needs to have 1080p or higher screen in 100% screen scaling, and the .NET Framework 4 for a small number of plug-in features.
Your computer's processor (Intel, AMD) should be recent enough that it can run AVX extensions.  Shader level 6 is required for GPU functions.  As of Howler 2023, GPU support cannot be turned off.  I GPU with high enough performance is required to avoid TDR conditions (timeout delay and reset)

See other System Requirements.
