Dolphin emu part 1 with Nvidia jetson nano 2GB
5Above I show the Metroid prime of Gamecube
Mortal Kombat
Xenoblade for Wii.
Metroid does not go at 100% speed to gain performance you have to lower the CPU to 50% when emulating a lower HW of gamecube you get better fps it lets you play even by uploading it to 1080p
1440p performance is not bad but less consistent than 1080p
The loss over 720p or native is minimal because the bottleneck is in the CPU and not the GPU in this game.
Mortal kombat works quite well without doing much even at 1080p there may be some drop but nothing appreciable at 43-45fps in some scenario
Note : the rescaling in this game causes some glitches around the letters.
Xenoblade does not have a stable framerate around 23-30fps but if the CPU to emulate is raised to 150%, the fps is more consistent.
I do not recommend uploading more than 720p in this game as the performance drops sharply from there even though 1080p in some areas does well in others it loses fps.
