It continues to be wild to me that DTG have not added this to the options on console as this is implemented as a third option on many Series X games. Some Series S games will go as high as it for their "quality" modes.
As said before, TSW1 and TSW2 routes can run on 4K on series S, so I'm very curious how the Series S will perform on 2K with newer routes. The biggest issue is the fact the FPS is all over the place, some parts are pretty good but big stations and/or many trains at one spot will drop the framerate. Even a lot of trees can hit the framerate hard. Frankfurt HBF on the Frankfurt S-bahn route don't have a solid framerate and this is with the reduced timetable, so there are almost no trains.
I would never even think of running TSW on Series S at that resolution, back when I was playing on Series X, I ran at 1080 for the performance uplift because I got migraines from the framerate running it at 4k...
Well, I'm playing on a VRR monitor for that reason, so I don't notice the framerate fluctuation. Without VRR, I can't play lot of games because of an unstable framerate and the stutters caused by it. But with VRR, on old routes the framerates are high enough to play on 4K, but I can imagine they are not stable, a FPS limiter at 30 FPS is still missing.
I'm on PC and I switched from 4k to 2k ( 1440p ) about a year ago and am getting very good performance without any visible graphics penalty. It really is the sweet spot for TSW and consoles should have that option.
Just a minor technical clarification, 2K as you call it would be closer to 1080p (1920x1080), whereas 1440p would be more akin to 2.5K (2560x1440).
I like to play in consoles, as I can play on a big TV and seated on my coach. PC does not provide this to me. I liked to play a lot to TSW in my PS5, but since TSW5 the game is not optimised at all. I enjoyed the last TSG route but that is. I was looking forward to the Frankfurt S-Bahn, but after it was cut, I did it not buy it. And the TSW6 I did download it, but have not played yet. I am very pessimistic about the future of TSW in consoles. If the base of the game are console players, which seem to be, the base game should be a console game and optimized accordingly. At the time veng, it is clearly not the case.
I play on my couch with a gaming laptop and the screen is nice and close. Best of all I get great performance and can apply all the lovely mods that vastly improve the game. No contest in my book.
The terminology shifted and the old DCI definition of 2048x1080 fell out of common usage as the resolution standard did, and most manufacturers of displays began marketing 2560x1440 to the general population as a mix of "2K" or "QHD" over the same period as it was a convenient shorthand for the third most common standard that fell between 1920x1080 and 3840x2160
I play on an ultra widescreen ( 3440 X 1440 ) which is another complication. I just call it WQHD. The " k " nomenclature isn't that useful anymore.
