The update also permanently fixed an issue where XInput and DirectInput game controllers randomly lost rumble feedback functionalities. Cemu 1.27.1 Performance Comparison

While Cemu 1.27.1 is a popular choice for the Steam Deck due to its stability, it is not without issues on Linux-based systems.

We tested three demanding games on a mid-range PC (Ryzen 5 3600, GTX 1660 Super, 16GB DDR4) to quantify the improvements.
