   - Mesa Drivers: Configure Mesa Drivers specific environment variables
   - NVIDIA Drivers: Configure NVIDIA Proprietary Drivers specific environment variables
   - Render Selection: Choose the renderers for both OpenGL and Vulkan applications
-  - Set frame limit for both OpenGL and Vulkan applications (requires [mangohud](https://github.com/flightlessmango/MangoHud))
+  - Set a frame limit for both OpenGL and Vulkan applications, and Texture Filters and MidMap LOD Bias for Vulkan only (requires [mangohud](https://github.com/flightlessmango/MangoHud))
   - All those GPU settings will be added to the `volt` script
 - Disk Configuration
