I'll be using my computer monitor, which hits a top framerate of 144 Hz and has a QHD resolution of 2560 x 1440 with HDR capacity. It also features G-Sync, though I doubt it will be useful on a PS5.
The game has a Performance 60Hz 4K setting, Performance RT 60Hz FHD setting, and a Fidelity RT ~40Hz 4K setting. If my monitor caps at QHD, 2560 x 1440, and I set the game to Fidelity mode, will the game receive all the Fidelity mode bonuses, and run at a higher than ~40Hz framerate due to the QHD resolution? Or is it locked to a 40Hz cap? I definitely want maximum visual quality, but if it's possible to get that extra performance boost, that would be sick. I'll literally get the game in less than two days so this question might seem irrelevant, but I figured I would ask to see if someone with better tech know-how could grant me some wisdom.
