Job update: I am leaving Ubisoft at the end of the year. I am very proud of the work I did on compiler optimizations on AC: Shadows and I will miss my co-workers there dearly. In the new year I will join the fine folks over at @larianstudios.com and work on compilers and builds. I am very excited!

2025 is shaping up to be one of the weirdest years I have ever had. Right now I just want to fast forward my life until 2026.

The #LLVM developer room is back for the 12th consecutive year at #FOSDEM, on January 31st! We're looking for presentations on all aspects of #LLVM, #MLIR and more. See CFP for details discourse.llvm.org/t/cfp-fosdem.... Deadline for submissions is November 30th. I hope to see many of you at FOSDEM!

I worked quite a bit on the toolchain stuff for this, hitting a consistent 30FPS was a hugely collaborative endeavour between toolchain, rendering and other engine work. It's the first time we ship a game with CSPGO as well, which helped in dense areas. Hope you enjoy! youtu.be/3oTfnzXb8OE?...

Went to the co-working office today and made a decent effort to find a fit. This shirt is pure autumn vibes.

One of the best and the worst weeks I have had in a long time... fuck this rollercoaster.

@rebeccafernandez.bsky.social if this is not RIGHT up your alley I don't know how badly I have read your taste in music :-) youtu.be/bCL4LUozdME?... Let me know if it's annoying with my music recs, but I don't have that many people that seem to have a similar taste in female fronted metal :)

LLVM 21.1.0 was just released! It's as always a pretty massive release with 19k commits from over 1500 authors. Enjoy! discourse.llvm.org/t/llvm-21-1-...

@mint-tamas.bsky.social have you heard pca.st/episode/8d97... ? I thought about you when I listened to the series :)

Running "git repack -adf --path-walk" in my local llvm-project shrunk the .git folder from 3GB to 1.7GB. Very helpful! Details about the new path-walk in git release blog: github.blog/open-source/... and www.jonathancreamer.com/how-we-shrun...

@rebeccafernandez.bsky.social This might be something you'll like - maybe a bit to far on the hardcore side, but there is something about the dynamics in this track that I love: www.youtube.com/watch?v=QTA6...

Reverse Birthday Present - Here is LLVM 21.1.0-rc3 for you to test on my birthday! discourse.llvm.org/t/llvm-21-1-...

Just discovered Landmvrks and this recording of Creature at Hellfest. Relentless and the singer Flo does an amazing job. Rapping, growling and belting. Top tier stuff: youtu.be/MmRoDovSZ1o?...

I just uploaded LLVM 21.1.0-rc2 - go check out the changes and file issues with problems you find! discourse.llvm.org/t/llvm-21-1-...

The LLVM 21.x release train has taken off with the release of RC1! discourse.llvm.org/t/llvm-21-1-... Go test and report issues!

After 2 months of work, the Clair Obscur Expedition 33 video is here. I interviewed most of the game's senior leadership team asking one simple question: how did you do this? Their answers were inspiring and moving, and it's no surprise that COE33 is as remarkable as it is: youtu.be/mXLOLgC2V2Q?...

It’s really cool to see my talk freely available for everyone. I’m proud of the work our team accomplished, and it means a lot that it’s now accessible to a wider audience. Huge thanks to the GDC team for putting it out there! #AssassinsCreedShadows #GameDevelopment #GDC2025

Expedition 33 is instantly jumping in very high on my personally GOTY list.

On sale now @ 99¢ The Mythic Island Press ebook edition of THE RED: FIRST LIGHT is now available worldwide. If you haven't yet encountered this Nebula-nominated novel, I hope you'll take a look. Near-future, military, first of a trilogy. More info at my website: mythicisland.com/the_red_firs...

Assassin's Creed: Shadows launch day! My first credited game! I am so excited and nervous! Hope you all enjoy it!

After an intense week of meetings and conference in Montreal I am home and have a week of. I will relax by ... remodelling our kitchen. At least I will have a bit of time to play FF7 Rebirth as well!

Back home after a week in Montreal. It was great fun to hang out with my team IRL, had great food and beer and many interesting discussions. My talk got very good feedback as well. With all that said. It's so damn nice to be back home.

Montreal has so much good food. I am constantly blown away about the quality!

My favorite gaming podcast is @friendspersecond.bsky.social - but just seeing the title of the latest episode makes me really anxious and not sure I can manage to listen to it.

PSA: Jonathan Blow blows. 👎

PSA: If you are playing FF7Rebirth on PC and have texture problems and soft-locks - try upgrading the DirectStorage DLL's. It fixed almost ALL my issues with textures. It's almost like they shipped the wrong version of the DLLs. Hope SquareEnix fix it in a patch soon.

I can't stop thinking about this absolutely haunting performance by Stephanie and Brutus: youtu.be/3_Vys58zvTk?...

Back in 2021, PMG reported on the unseen games industry crunch taking place at outsourcing studios in SE Asia. Since then, the companies we looked at have continued to work on some of the biggest games in the world, without any push to improve the conditions of the artists doing that work. (1/7)

LLVM 19.1.6 was just released! discourse.llvm.org/t/llvm-19-1-... This was the last one for the year! Now I will be on a break for a few weeks!

Finished BG3 finally! But I almost want to jump in to a second play through right away! I feel like I missed so much!

LLVM 19.1.5 was released earlier today! discourse.llvm.org/t/llvm-19-1-...

Very happy to have landed some really aggressive optimizations for an upcoming game today. ThinLTO with whole-program-vtables plus PGO and the basic block reordering. Ended up gaining around 10% performance on the CPU frame on PC. It's been a long road with testing and iteration.

It's so fucking demoralising at times.

Looks like I am going to Montreal in February! What should I not miss?

It's snowing in Scotland, which means the gritters are out. Indispensable logistical workers such as Gritney Spears, Gritty Gritty Bang Bang, and, my personal favourite, Skid Vicious

Finally getting around to play Baldurs Gate 3! Wonderful writing, characters and world. I like the combat (but I am not very good at it) and have a lot of decision paralysis at certain choices! I know this isn't a novel take, but I wanted to make sure to show my love. We need more games like this.

Happy to announce that LLVM 19.1.4 was released a few days ago: discourse.llvm.org/t/llvm-19-1-...
