Update, because I wanna let some guys here know I found the perfect option to update Deus Ex.

There is a mod called Deus Ex Transcended and it gave me exactly what I wanted. General bug fixes, High Resolutions, and Weapon FOV fixes.

While still keeping the whole game generally vanilla. With options to improve the game in ways the original never incldued. Or even HD graphics options like Hi-Rest Textures and such. But again all this is optional with this mod and you can choose to play the game as vanilla as it can be with the fixes and resolution options

I am baffled this mod wasn't suggested and listed in PCGamingWiki

I used Give Me Deus Ex (GMDX) and it was pretty vanilla while enhancing quality of life.

But maybe not from a shitty FANDOM wiki, yeah?

Just the website will do.

Yeah, was not providing a download link but an informational one. Thanks for pointing out a download site.

GMDX changes a lot of things though.

A merely graphic enhancement mod would be New Vision. It's the one I used. No problems whatsoever.

Yeah, this has a basic version that just enhances the existing game and I use that (along with Deus Exe). Works like a charm. Bloodlines has a similar "no new content" version of its stuff, IIRC.
