If you want to play Deus Ex the way it was originally designed, with no gameplay changes or visual reworks, I put together a full step-by-step guide. It uses Kentie’s Launcher, a proper DirectX 11 renderer setup, fixes the GOTY map issues, and includes accurate upscales that stay true to the original look.

No reimagined levels, no altered mechanics: landingtarget.com/deus-ex-modern-vanilla-experience/

Can not find the proper site with your link. Another try maybe? Thanks.
Edit: Found it! :), thanks again.
