How to Boost Performance in Suyu up to 80%.

If you are using Suyu but aren't quite happy with the default performance you are getting on your devices this article will show you quite a few different things you can change and customise to get up to 80% more performance from Suyu. While 80% is the peak and kind of hardware-specific, the average user will still see some fairly decent performance gains after making some of these changes.

How to get Better Performance in Suyu Emulator.

If you'd like to toggle between graphics modes and settings in Suyu, you have two options tailored to your preferences. First, head to the Settings menu, where you'll find a comprehensive guide on mode switching. Alternatively, for a quicker transition with minimal setup, utilize the icons located at the bottom left corner of the Suyu window. These icons not only allow mode switching but also allow you to adjust GPU load conveniently.

You can even tweak graphics modes and settings during gameplay, and witness the changes in real-time. However, remember that the game you're playing is the key determinant in this process. Some games will have significantly improved performance with Vulkan on NVIDIA hardware, while others are better in the opposite configuration.
