My time at Unity is coming to a premature end, with our consulting team being dismantled.
That means that ✨Sparkling Code✨ is available again for all your C++, performance, graphics and gamedev needs, now with premium Unity expertise too!

Late mid-week graphics update.
I toyed a bit with TBB's flow graph instead of crude parallel_for/parallel_invoke and it's really good at maximizing core usage.
Bistro now starts in about 2s with mesh LODs built on the fly.
AI is useful to set-up a prototype for unfamiliar API.

Je vois pas mal de Français qui ont encore beaucoup de mal à comprendre pourquoi Jensen Huang est poussé dehors, alors qu'il trompait sa femme en ayant une liaison avec une subordonnée sous ses ordres directs. La partie importante c'est pas "trompait sa femme".

"Fiduciary duty" doesn't mean "tolerating improper relationship with a direct report and doing deals under the table just because else it would be bad for the share price"

[Desiree Fixler @desireefixler]

I fully back Jensen Huang.

The good news: every Nvidia board member is a shareholder. All 11.

The bad news: this is starting to look like Succession. And coincidentally, right after the Democrats' midterm sweep.

Jensen built Nvidia from nothing into a $4 trillion company. Shareholders, employees, consumers and America all won. Now the board is considering ousting him over his private life and leaks, before its own investigation is even finished.

Fiduciary duty means protecting shareholders. Not feeding a bloodthirsty media frenzy.

I'm putting together a team 🤮

[Mathieu Ropert @MatRopert]

Sounds like we're about to hear a lot of dudes come out of the woodwork in defense of a serial adulterer who had a relationship with an employee he had power over as her boss.

@icculus @VagabondTruffle I'm glad I found my answer in the mentions I admit I had almost given up with all the notifications 😅

@AlanDersh Hello Alan this is your lawer speaking. I am advising you today to please keep posting this shit

@righttakurou @IssekiNagae Do Japanese history books look like this?

[Mathieu Ropert @MatRopert]

My consultancy would have happily looked at this but if I'm being honest I don't expect anyone to hire Sparkling Code on a 4 man indie budget just to tweak one Unity URP setting.
Still happy to help other projects though. And my AI policy is client decides if allowed or not.

Big Walk used AI in 'the final stretch' of development, kicking off intense awards debate:

@JoyceStartSouxi @SkyTieds @is__Kaizo You could say they harm my job has a consultant who offers unity project reviews and general software performance contracts.
But I doubt a 5 person studio will ever go through the process of hiring my services for this, AI or not.

[Mathieu Ropert @MatRopert]

@OlexGameDev @StokeWillie Microsoft has been steadily burning the goodwill they gained during the 2010s with their recent refocus on AI above all else.
MSVC, vcpkg and co are all underfunded.
Then again, I'm told the open source ones I've also seen reduced contributions.

[Mathieu Ropert @MatRopert]

@ChristerEricson This has nothing to do with Modern C++.
Compilers have diverged on how they parse and instantiate templates since the 90s if not earlier.

[Mathieu Ropert @MatRopert]

@VagabondTruffle @icculus Wait... having AI found the bug disqualifies for making a fix (or even reporting it)? Surely that's not what @icculus' policy meant.

[Mathieu Ropert @MatRopert]

@arvidkahl Unrionically yes

[Mathieu Ropert @MatRopert]

@SheriefFYI I implement deferred deletion with RAII types. It's just about moving them into the deletion queue and then clearing it at the appropriate time.

[Mathieu Ropert @MatRopert]

I finally saw the De Gaulle biopic. Feels like someone wrote a 5h movie in 2026 called "Do Not Trust the Yanks".
But turns out no, it's a mix of a 2019 British biography mixed with the experience of a war on terror era french diplomat.
The more things change...

[Mathieu Ropert @MatRopert]

Angry reactions to this on 🦋 baffle me. They used an LLM to fix an issue Unity support couldn't/wouldn't.
1. it's the 2026 equivalent of googling a tech problem
2. Unity support would likely use an LLM to answer
3. The whole engine is made with AI assist!
