This has been a great year for the engine, but there are still a lot of things we would love to do. If each person visiting our website donated €5, we could hire 5 more developers to work on Godot full-time. 👉 fund.godotengine.org

Ever wondered how to store millions of call stacks efficiently? So did we. Many times. Check out this new article by Jelle about designing a data structure to efficiently compress and store large amounts of call stack data! superluminal.eu/compressing-...

That's an instant subscribe 🥳

I wouldn't say that I'm opposed to new tech in general, but yesterday I had to update the firmware of all our light switches(!) one by one, because some of them stopped working out of nowhere and now the light in the bed room can't be turned off anymore 😤

Kinda funny to see Tim Sweeney claiming that AI is going to be part of 'nearly all' future games, while at the same time, AI-generated code is bad enough for Epic Games to have a strict No-AI stance when it comes to Unreal pull requests. www.gamesindustry.biz/epics-sweene...

Nice, my tooltip fix made it into an Unreal Fest talk! youtu.be/M1J25jJ79U8?... (Following 5.8 it won't be necessary anymore, luckily!) #ue5 #gamedev

Good news! Epic submitted a fix for this issue! The even better news is that they didn't just merge my proposed fix but wrote a better one, which can even handle arbitrary tooltip types, not just text-only ones. Much better outcome than I could have hoped for 🥳

Gave a lecture today using a windows PC that wasn't my own, so mostly using default settings. Twice(!) during this lecture Windows decided to open a "news & weather" popup in front of my slides! It didn't even have a normal close button. Is this really the 'default windows' experience nowadays? 😵‍💫

As a game developer spoiled by dozens of fast CPU cores I always find it amazing to see games running on decades old hardware. In my blog post I take a look at one of the optimizations to run the original SimCity on the CPUs of its time. #gamedev #retrogaming larstofus.com/2025/11/16/h...

TIL that Path of Exile has two different, fully implemented networking modes (Lockstep & "Predictive"), which players can freely switch between o.O I don't know of a single other game that does this, most developers are glad if they get one mode working properly.

Does anybody know what the first first-person game was that used a full body mesh instead of a floating pair of arms? In my own gaming history the first game that did this was Dark Messiah (2006), but surely there must have been others before it, right? Googling this is harder than expected :/

Because of reasons I currently use more blueprints in Unreal than usually (normally I work in C++). I constantly stumble over small UI quirks that I never noticed before. Like the function inputs/outputs list. You can use drag & drop to change their order but only in the according subsection (1/2)

This sounds like a joke, but I deleted a file by accident and I am *actually* struggling to find the windows recycle bin. It's not on the desktop, not in the start menu and the windows search also can't find it. I even made a screenshot to make sure I'm not going mad 🫠

I'm mostly ok with modern games trading image clarity for performance, but can we discuss the level of "acceptable noise" again? This is an actual, unedited screenshot from the Halo Remake 😵‍💫 It looks like a bad scan of an old print magazine

If you regularly use the PC Gaming Wiki, for example as reliable source to get older games working on modern systems... consider backing up the pages you are interested in ⚠️ According to staff members on their discord, none of the active staff members have full access to the backend anymore. (1/?)

Just taking another look at the new Unreal FPS Template project because I need an example project for an upcoming lecture. Already on the first step you take you can notice that the new hands clip into the camera at every single step (screenshot attached). Feels a bit rushed tbh.

Wait, what?! I read through the whole article without noticing that part 😱 Really looking forward to it. Right now Superluminal is one of the very few applications left that I couldn't easily replace when switching to Linux 👀

New blog post! In "Billions of triangles in minutes" we'll walk through hierarchical cluster level of detail generation of, well, billions of triangles in minutes. Reposts welcome! zeux.io/2025/09/30/b...

It's understandable that Unreal needs to touch a lot of files when starting the editor. But what if I told you that >5500 of those files are not needed for the editor to start at all and are just adding seconds to the editor launch time? (Fix included!) #u5 #gamedev larstofus.com/2025/09/27/s...

Are you or someone you know skipping GDC (or considering doing so) because of worries about coming to the US/San Francisco in the current environment? If so, I want to hear from you for a piece. DM me here or kyle DOT orland AT arstechnica DOT com. Please spread the word

Becoming obsessed with adding QoL features to the Mip Explorer: - Navigate directories with the arrow keys - Taskbar notification when directory scan ends while app is in the background - Resizable UI - Support for single-channel textures (ok, not just QoL) github.com/HaukeThiesse... #gamedev

Just noticed that 5.7 is the first UE5 version since 5.0 without any explicit Lumen improvements on the roadmap 🧐 Guess MegaLights is the focus for the next few releases?

With the latest update for the Mip Explorer, it now also reads and compares the alpha channels if existent, and can process entire directories, returning the results in a sorted list. The goal is to turn this from a toy into a tool for actual production. github.com/HaukeThiesse... #gamedev

Attention fellow AUSTRALIANS! 🇦🇺 We now have an official petition to parliament to STOP MASTERCARD and VISA from its campaign of censorship, restricting what legal products we can buy. Please sign it now, and if you're not an Aussie, spread the word! www.aph.gov.au/e-petitions/...

There are a lot of reasons why starting the Unreal editor can be slow. In my latest blog post I fixed 38,000 of them. #ue5 #gamedv larstofus.com/2025/09/02/s...

In a recent talk I called Rollercoaster Tycoon 2 one of the best optimized video games in existence, and there probably aren't many big savings left anymore... Well, just weeks later it's open source re-implementation made the creation of savegames 12(!) times faster 🏎️ openrct2.io/blog/2025/08...

Hi authors! Please remember to file a claim!

Do you have a gamedev blog with RSS active? comment with the link, I'll follow, let's spread a bit of love for good old blogging! mine's in bio if you want.

We've made Property History free & open source! You can use it to quickly see the history of any property in Unreal github.com/VoxelPlugin/...

On my way to Gamescom now! And my train is only 15 minutes late (so far🤞)

Even Wikipedia isn't safe from being flooded with AI slop! I hate this timeline😠

Optimization tip for owners of small fur factories aka cats: Consider cleaning your PC or laptop from time to time and getting all of the hair out of the fans. Did it this morning, and now I have to re-profile a bunch of stuff because my average frametime was cut in half 🥲

I did a blind test today to convince someone that buying a 144 Hz monitor would be a waste of money, since they only play slow-paced games like JRPGs and wouldn't be able to tell the difference from 60 Hz. Welp, I was proven wrong.

It would be a boring weekend without a new blog post about game optimization: haukethiessen.com/introducing-... This time, it's about the genesis of a tool that I wrote a while ago to identify overly large textures. #gamedev

My new blog post is there, and it's a bit different from usual: Fixing stutters in your own code is hard enough, but this time I try to fix performance issues in a closed-source game. No source code or debug symbols, but a lot of guesswork. larstofus.com/2025/07/27/p... #gamedev #Trackmania

Hot take: If your application's UI contains a list of elements with potentially more than 1000 entries it also HAS TO contain a search bar for this list. No discussions, no exceptions! (Looking at you, Process Explorer) 😭

The idea of filling websites and blogs with AI slop is nothing new. However, this site takes it to a whole new level by writing articles about how to write performant code for Unreal Engine 6 (not a typo) and even inventing new features such as "Nanite 2.0". markaicode.com/cpp-unreal-e... 🫤

The new blender release halved the start time, probably because somebody on the team deemed 7 seconds too slow. (I am reading the release notes and writing this text while I wait for the Unreal Editor to start 🐌)

For the next two days you can find me at the #GermanDevDays in Frankfurt! Talk to me if you are interested in gamedev education, optimization or just want to see some pictures of my cat 🐈

I see this and I'm reminded of that study that shows people literally becoming dumber when overrelying on genAI and I wonder that's what is happening here Like, I'm seriously concerned when people in executive positions are lobotomizing themselves and what that means for the economy and progress

A good example why I am not a fan of instrumentation based profiling - you can only see what the instrumentation wants you to see 😶

UE5 uses a lot of memory. TIL that >50% of it could be untracked! Would have never expected that so much memory used by core systems like Nanite or Lumen could be untracked and thus not possible to investigate with Unreal Insights dev.epicgames.com/community/le... #unrealengine #UE5 #unreal #gamedev

I have rarely been that impressed by a chart design, marvelous work!

After being frustrated with Artstation's blogging options for way too long, I finally moved to WordPress🎉: haukethiessen.com All posts so far did survive the move. I'm still getting used to the newfound freedom and polishing the new site, so please let me know about any rough spots. #gamedev

In preparation for my talk at Unreal Fest Bali this week, I've made a small blog post on how to create a custom FMaterialShader in Unreal: victorcareil.com/making-mater...

Out of curiosity: Does anyone know if @audiokinetic.bsky.social accepts pull requests for #Wwise? Specifically the Unreal Engine plugin? I couldn't find a GitHub repo anywhere 😶

Since the release of 5.6 Unreal's roadmap isn't roadmapping anymore, it just shows already released features😑
