Always take in account that TSW uses skeleton meshes for trains and characters, and dynamic flora a lot. Both will not benefit from UE5 at all yet because Nanite does not work with them. Only the static scenery could benefit but with that, i would say, you would not even see any difference. Only thing that may have a positive impact us Lumen with its nice realtime GI.
An interesting read. By the looks of it tsw2 is nowhere near this on the basis that its requirement for decent fps would likely wipe out 75-85% of its player base. i had bad performance on a 2080ti, i9 10900. I'm not prepared to Chuck £4K at another pc yet. https://www.eurogamer.net/digitalfo...ands-on-the-cost-of-next-generation-rendering
From my point of view, there are three things to consider. 1. You were running your test in editor, which gives you siginificantly worse performance compared to a shipping build. 2. Lumen is effectively disabled unless GI settings are set to high or above, which gives a pretty good chance to lower-spec systems. 3. The demo was supposed to go "balls to the walls", which affects performance about as you would expect (Check the Lyra demo for something more reasonable).
