But APIs are vastly different according to graphics and engine dev, Dale Weiler. The whole thread is pretty interesting to read:
Very interesting and right.
I mean I'm telling that below since I entered in GAF but people still believes that there is some magic that makes it runs well in every single platform... even using multiplatforms APIs like Unreal Engine (remember when I have to make a video here in GAF to prove somebody that in UE4 you should still do different code path to nVidia and AMD and that the Engine even support these differents code path) you should still do specific platform code path optimizations to reach the desired results.
PC hardware is the most unoptimized thing in any type of development but that is the nature of PC... the results you can get with a RTX 3090 today you will only see in games several years ahead with way more powerfult hardware GPUs.
If some crazy developer choose to develop and optimize a game for a single GPU in PC like RTX 3090 the results will be shocking and way ahead every game you have today.
