1/4 AI usage warning post
AI is trained on human data. The problem?
They make mistakes that persist for years.

The BT.601 color space was dropped ~25 years ago, yet google insisted on its coefficients for any color questions, causing a snowball effect that kept spreading it.

I've release a Luma HDR mod for Heavy Rain, a game that was very influential on me growing up!

While reverse engineering loads of games, you start to see patterns. A big mistakes many devs made in the last 20yrs is decoding Bink videos as BT601 instead of BT709
Likely due to Bink docs not being updated from early 2000s

Mafia III has ~40m of videos, which one looks right to you?

I released an HDR mod for Thumper!
Game made magnificent usage of color.

Game is a perfect showcase of HDR (SDR on the left in the comparisons).
Download it here tinyurl.com/mb6uxr34, turn off the lights and try on an OLED TV, you won't be disappointed.

I couldnt help but notice almost all IGN uploads trailers have shifted colors against the original version (xbx/ps/devs yt page)

To add a logo, not only they butcher the quality of anything in movement , but also mess up all colors, failing to show the game as originally intended by its artists

Great Digital Foundry analysis of our new CONTROL patch
tinyurl.com/2datxhks

Gamers seem to be loving the ability to unlock the frame rate
Having a toggle for PSSR also seems quite appreciated, leaving the sharpness vs higher frame rate choice to players

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

After wanting to do it for years, I finally found the time to write an all encompassing guide on HDR, with a focus on gaming.
Hopefully you won't be confused by it anymore, this covers all the basics.
You can find it here, on our new subreddit!

Just so it happens that I released a Remastered mod for Deus Ex Human Revolution the day the DX remaster was announced
I added HDR rendering+output, improved SDR, fixed 4k and Ultrawide support, + fixed graphics issues

The state of HDR in the game industry right now is catastrophic.
Silent Hill F, AAA game, shipped w/out color grading in HDR, on top of the raised blacks that come with all UE HDR games

It doesn't look as it's supposed to in HDR, atmospehre is completely gone, devs either didn't know or care for it

New HDR+Ultrawide mod: INSIDE
an absolute gem
Reverse engineering shaders was very interesting as they did everything in a unique way, bespoke for a side scrolling horizontal view.
As usual, a large amount of data being lost due to the presentation being restricted to SDR.
September 22, 2025 at 4:32 PM
I don't really like to offer customizations that stray much from the artistic intent, especially in case where it influences gameplay, but a lot of players were asking for customizations on the character light, so I've added an intensity, radius and falloff parameters.
Ready for download!

This is how bad banding was without my HDR mod
For some reason the hero light sprite is extremely low quality and quite distracting in dark areas (most of the game😁)

Plus, the whole rendering was 8bit, so if you stack multiple post process effects, quantization hits pretty fast!

I released a mod that adds HDR to Hollow Knight: Silksong.
Given the small team, the game doesn't support HDR and suffers from bad banding

I've also improved the SDR tonemapping (there wasn't any, it was a raw rgb clip), and fixed banding

Me and my collaborator Ersh threw out a quick (but carefully done) mod to fix the massively raised blacks in Cronos.
nexusmods.com/cronosthenew...
This is from the same developers as the Silent Hill 2 Remake, which is graded very similarly and that we also fixed.
Black Floor Fix
Shader replacement fixing the black floor raise prevalent in the game, especially noticeable on OLED screens and in HDR.

Somebody made a video about my COCOON HDR mod (one of the many of my LUMA project), check it out!
This game had so much potential for more dynamic range, it's transformative:

I've been working on PCSX2 (PS2 emu), adding HDR rendering and output
Given how the HW worked, everything is a blend: both vertex lighting or additive draws (lights/particles) produce values beyond the SDR range (0-255) that were just clipped. They look glorious in HDR

I've made a mod that adds HDR to good old Bioshock!
Here's a showcase of it: www.youtube.com/watch?v=garC...
Older games still rendered to HDR internally, but then clipped to SDR before output, so a ton of detail was going lost. The game looks stunning in HDR, still feels fresh in 2024.
