No, it’s most definitely a choice. You can make any engine run at 60 FPS if you sacrifice something else for it. The RE engine runs beautiful games at 60 FPS, but they had to make all sorts of sacrifices to fidelity to get World Tour in Street Fighter 6 to run at all, let alone at 60 FPS on current gen consoles.
I no longer trust triple A games on PC and if the game is not ridiculously busted optimisation wise for PC at release I would be amazed.
I mean sure but give us the choice, damn it! :(
Depends on what is causing the framerate issues. If it’s usual fidelity (resolution, draw distance, visual effects) then yes, they can provide options for those.
If the framerate issues are due to physics, NPC/interactions, state-management then it’s unlikely they could or would want to provide options around that type of limitation.
