Cemu

I used to play Paper Mario Color Splash in 1.19 last year at 1600x900 locked at 30 fps. After the 1.20 update I noticed a little downgrade and currently the game is unplayable in my system. At 1280x720 (native) the game runs at 7-10 fps. It stutters a lot as well, in the title screen for instance, when it boots I get 14 fps (Image 1), but after 30 seconds when Mario enters the screen it goes to 20 fps and even 30 sometimes (Image 2), there are no signs of shader or pipeline compilation in the meantime. In-game the fps is around 7-10 (Image 3). I find this huge downgrade really odd, specially after the awesome upgrades in pipeline compilation and in the Vulkan API, for the sake of comparison, Breath of the Wild runs locked at 30 fps. Feel free to request me some logs if needed, I don't know if this is a problem only for AMD GPU's or my system specifically. Thanks in advance.
