And our opinion is that we aren't starved for performance on DX12 cards (and as you said it's "possible performance" since it's not guaranteed to actually be faster for our usecase) and I don't know of any "features" in DX12 that we can't get through OpenGL extensions that would get us more "accurate emulation".

I didnt said its possible performance increase, some performance increase is given because of nature of Directx12 and WDDM 2.0 however I agree that modern GPUs arent exactly starved for performance in PPSSPP.
But removing cpu overhead and abstraction layer alone should help because consoles were always lower level than PC API's until now. Well Dirextx12 hardware features arent really known yet so you cant compare them with OpenGL at best you can compare Directx 11.2 features with OpenGL 4.4. Still even old Directx 11.0 is better than OpenGL ES 3.1.

I understand Henrik will add what he want but PPSSPP is already working on Android so that goal was achieved long time ago. And by the way I am not even remotely rich myself but I rather save up some money than use ancient cpu/gpu which can cause subpar performance and graphical glitches.

I'm not being rude but you don't seem to understand the point of this thread and the purpose why we need to have DirectX backend support. You suggesting that DirectX 12 should be use merely because it can increase performance. But no, we need at least DirectX 9 to actually make it work for low end OpenGL devices, it's not about the better performance that we seek.

Yes you can save up to get a new GPU but unlike you we have other priorities to spend our money like food and stuff. Also different countries have different prices for the same GPU. Example, a GPU might cost $80 in US but in my country it's more expensive than that.

And no, not all Android devices can make PPSSPP run perfectly so it's still far from achieving his goal.

Well you are rude. I know what is purpose of this thread but right now I am discussing about merits of Directx12. I didnt suggest Directx12 just because of performance increase and I dont really have anything against Directx9 backend but in my opinion Directx9 or not Directx12 would still be useful. I am not american either and electronic equipment is damn expensive in my country. Making PPSSPP run perfectly on Android is very hard because Android as operating system wasnt really designed for high performance gaming , most of Arm cpus are pretty weak, mobile gpus have often buggy drivers and Android devices use OpenGL ES which is castrated version of real OpenGL not to mention PPSSPP doesnt run ''perfectly'' yet even on Windows.
