COSMIC is a new and exciting desktop environment for Linux, designed to provide a seamless and modern user experience.
This repo isn't focusing on performance differences from other desktops. It's focus is just to share that these games are indeed working like they should and are playable on COSMIC.
- Game Compatibility Testing: Verify if popular games run smoothly on COSMIC.
- Performance Benchmarking: Measure and analyze game performance.
- Optimization Tips: Provide recommendations for improving game performance on COSMIC.
