[Request] Is it possible to "fake" mipmapping?

Hi there

Yes, my question in the title might seem a bit odd, let me explain:
I am currently working on a texture mod for the recent Nightdive remaster of Turok 2. The problem is, the Kex-Engine has no mip-mapping functionality (i think that might be because of all the screenspace effects).
Now the highres textures i created tend to alias and flicker as hell with increasing distance - it's quite eye cancer inducing.

So, would it be technically possible to write a shader which does a similar thing to mip-mapping to milden the flickering?
Depth buffer access is given (DoF works for example).
Please forgive me that n00b question, i am quite new to the world of reshade

Thanks in advance,
Wakey

No. That's not something you can do in screenspace. What may help is to use a sharpen or blurring filter to make it less visible.

Thanks for the fast response

Just as i thought, a bummer. I tried out both blur and sharpening filters and either makes the flickering worse. The aliasing is so severe, that even with a strong gaussian blur, you get a flickering blur
The only solution is downsampling, but that is quite performance intensive for now.

If you want a distance detail reduction try setting up DOF to static focus with a really shallow far curve and no near curve.

Tried that, unfortunately the flickering is so severe, that even the blurred parts flicker like hell. And that even looks worse.
Originaly i asked because i want to use DOF for that game, but with the flickering it is a no-go.
But thanks for your thought anyway, i appreciate it
