Ignore the remake and play this on Deck instead on highest settings.
Camera with right stick is sub par on default (game's vertical cam axis has a higher sensitivity and higher dead zone than horizontal, and I just remembered this being critiqued already when it was released back in the days), but setting right stick to joystick mouse with a 100% sensitivity works much better, since the game treats mouse input linear on both axes. You'll lose right stick push for the objective guide line then, but that functionality is still available by pushing right track pad, which I personally find to be even more comfortable.
Seems to be capped to 60FPS internally even though there's a 90Hz resolution setting, but that's fine.
Deck's (OLED) brightness set to 50% and brightness in game set to lowest recreates the original dark experience.

Masterpiece. Really they nailed the game, its so advanced and ahead of its time. Graphics is excellent, the way user interface is integrated in in-game world... Overall horror atmosphere and inspiration from older sci-fi horror movies like Event Horizon, Pandorum, Pitch Black, they really did great job. Level design, and design & variety of enemies is also on another level. Combat and weapons are very innovative and fun, also bench and ability to upgrade firearm and stuff is really cool feature that has impact on gameplay.
