Optimizing AetherSX2 Settings for PC
If your games are lagging or not looking how you want, then you can fix most of it by changing a few settings. I will tell you what you can do:
- You can use Vulkan or Direct3D 11 if you have a good graphics card. If your PC is older, then try OpenGL instead.
- You should keep the resolution at Native for better speed, or raise it to 2x or 3x if you want sharper visuals and your PC can handle it.
- You should make sure the Frame Limit is set to 60 FPS so games run smoothly without going too fast or too slow.
- Turn on Speedhacks like MTVU and Fast CDVD, because these can give you a nice boost in performance.
- Set up your controls the way you like, whether you are using a keyboard or a controller. Comfortable controls make a big difference.
- Save custom settings for each game so you do not have to keep changing things every time you play.
- You can turn on Widescreen Patches to fill your whole screen without stretching the image.
- If a game still feels slow, then try to lower the resolution or switch to a different renderer until it runs better.
