Rendering backend question

[Shady Guy Jose]

Hi! I'm sorry if this has been asked to death, as I assume it's a common question, but I can only find 8-year old information.

I use PPSSPP on two devices. Mainly my phone (OnePlus 9 Pro, Snapdragon 888, running at 1440p120) but occasionally on my desktop PC (i7-4770K OCd to 4.4 GHz, 32 GB DDR3 1600 MHz RAM, newly added RTX 3080 GPU, on a 2160p60 display).

I'd like to know what the differences between rendering backends currently are. On Android, I assume Vulkan is outright better, since OpenGL driver support has always been spotty, even if Adreno GPUs are the "least horrible" of the bunch, at least until AMD on Exynos comes out. However, on Windows, I see that D3D9 and 11 are available, and I assume OpenGL works better than on Android, at least with an nVidia GPU, so I'm a bit lost. I've read that D3D didn't support post-processing shaders, but it was old info. Is there anything that I can read up on, or does anyone have some insight into this? Whatever default you guys recommend, are there any games that I should watch out for and choose a different backend specifically for them? I'm just trying to figure out what to use.

Thanks in advance
