Hi, I made a small mod using SweetFX to add back the gold filter from the original game. Also added in a few extra stuff like SMAA, sharpening, dithering, contrast and color correction.

Extract the files inside the folder into your game folder. Use Scroll Lock to toggle it on or off, Printscreen to take screenshots. TO TURN ON the the filter, open SweetFX_settings.txt, then set USE_SEPIA from 0 to 1
Unrelated to the mod, but those with fps issues need to use this fix:
1) Open the Registry Editor (open the Start screen/Start menu, type regedit, press Enter).
2) Go to HKEY_CURRENT_USER\Software\Eidos\Deus Ex: HRDC
3) Find "AllowJobStealing" and set it to 0
4) Nvidia users only: go to HKEY_CURRENT_USER\Software\Eidos\Deus Ex: HRDC\Graphics and change "AtiForceFetch4" to 0
