I ask the mighty Dege for help/explanation 😁
dgVoodoo2 is not the cause, but maybe can be A solution for this strange issue this 2 games ("UE 1.5") have since 2003/2004.
Here's what I mean as "blur", you'll see it really well using 1/4 resolution (1280x720 instead of 2560x144) and then integer-upscaling
PNG images so NO compression artifacts!
No wrappers, no reshade, only dx8+visible upgrade ( https://www.moddb.com/mods/deus-ex-2-visible- … -update-edition )
And of course Bloom is DISABLED!
2560 (slightly visible blur)
1280 (visible blur along the door lightbar profile - no possible fullscreen problem 'cause it's done in windowed mode and then integer-upscaled -> and as you can see the HUD IS NOT AFFECTED BY BLURRING )

So it's something before in the rasterization pipeline!
Just take a look to the "jaggies" (aliasing), they're not right (not SHARP, as they must be in a PNG lossless image), like there's some kind of filtering already applied (no AA, no Bloom) or wrong internal resolution.
Always thought (since 2003, 🤣 ! ) it was a bloom side-effect, turned out to be false!
You can see the issue very well on a Quad HD monitor using 1280x720 and then an integer upscaler (upscaling with no bilinear filtering, just brutal 1 pixel -> 4 pixels ).
There's something smoothing the image in the rasterization pipeline, as you can see in the 1280x720->2560x1440 image. That blurring along the contours would NOT be present otherwise.
