Honestly there are tons of examples of games that run on low-end hardware that don't make anything like the full potential of the 3000 series cards. Most big games are console-focused these days, they're simply not optimised for PC in the way RDR2 and Cyberpunk are for example.
You guys are not understanding how a graphics engine is designed. They are agnostic of hardware. When Disney announced the Principle BRDF shader library using PBR, the developer implements those functions within the graphics engine. Specular model using GGX, diffuse model using Oren-Nayer, reflection model using a Fresnel attenuation function, etc.. We implement those functions regardless of whether they are too costly or not for the hardware. A full featured PBR shader system will use all of these models accumulated. When we run the game, we can see which settings in the shader are too expensive for low-end hardware and crank down the accuracy or number of samples for each of the BRDF models. We won't create a low-end setting and forego all the potential functionality of a high-end model that's close to the Siggraph paper simply because we are forced to design based on 1x000 - series cards.
HBAO can't run on a PS4
16x anisotropic filtering is too expensive
higher LOD is too expensive
Higher resolution textures and normal maps are too expensive
Shadow map resolution is too expensive
RT GI is too expensive without hardware AI for supersampling
RT shadows of every object in the scene is too expensive
Using full resolution framebuffer for RT reflections is also too expensive..
I can go on and on.. and yet, ALL of these things are presented in the graphics options in a PC game whether it's a 1st party title of a PS exclusive or a multiplatform game from a different company.
The low end model graphics cards are NOT going to be able to run these kinds of features at full resolution optimized or not. Same with these consoles. No 1st party game has any of these features indicating that optimizing the bare-to-the-metal code isn't enough to offset the ms cost.
You guys need to stop with the wizard of oz reality that games aren't optimized for the PC or games are designed around a low end GPU. PC versions of games are the fastest running and fully featured over the consoles. The fact that there are options that are in the graphics settings and not present in the consoles should prove that they don't develop games based on low-end hardware because those settings wouldn't have the ones that will choke the low-end hardware.
