First, from all the ones I’ve installed, they have all been all in one units with the heat pump on top of the tank that use the room air as the source. Not saying split hp water heaters don’t exist, I just haven’t seen any. The install for these units is practically identical to a standard electric water heater except you need to pipe a drain for the condensate.
The ones I’ve seen also include a resistive element and can act in a hybrid mode where they heat the water mostly with the heat pump, but can use resistive to boost the temp.
I agree to some extent. Elden Ring had little reason not to support ultrawide resolutions, but games that are very ui heavy, like the persona series, would require a significant amount of work to scale to the less common ratios. Ultimately, those of us who run oddball aspect ratios (anything but 16:9 these days) make up very little of the market share, so I get why some don’t support them.
