Conferences can be super busy; it can be hard to find the time to eat dinner. Fun fact: hors d'oeuvres can be a dinner if you just eat enough of them! 🤯 Pic related: me gobbling down finger food while the other person talks.

My coworker Zhi Kang Shao just published the Level Streaming Hitching Guide, a huge resource on the things you can do to prevent hitches during level streaming. Read it here: dev.epicgames.com/community/learning/tutorials/qpll/unreal-engine-level-streaming-hitching-guide

"Mafia: The Old Country: Using MetaHuman in a AAA Character Pipeline" is a fantastic talk on Hangar 13's use of MetaHuman for their amazing-looking characters! 🤩 Watch it here: youtube.com/watch?v=V8rL1r_1IcQ

Ari and I both said a lot of words on stage at #UnrealFest Stockholm, and I think these are the most important. How to think about profiling, how to read the unicorn barf that is Unreal Insights, and tips for looking at GPU captures.

How do we profile games at Epic Games? Check out this presentation where @mattoztalay.bsky.social and I examine perf captures from Arctic Hazard's "NORSE: Oath of Blood" and show you how to use Unreal Insights and PIX. www.youtube.com/watch?v=C-Aj...

Hæ from Reykjavík! Huge thanks to @flassari.bsky.social for being part of the very first Reykjavík Game Summit, and for capturing this great moment along the way! 📸

I was lucky enough to be part of @flassari.bsky.social ’s excellent 101 Tips & Tricks at Unrealfest Stockholm, which is both useful and a really fun watch. At one point, I do wrestling promo voice :) Now online, go check it out if you're an Unreal Engine gamedev! youtu.be/4w0PWcRwyOc?...

When an Unreal 5.3+ game runs, it will immediately kick off precompilation of global shaders. You should wait for that to complete before starting the game, otherwise you'll likely get hitches. You do that with the NumPrecompilingPSOsRemaining node. #uetips

I got to be a part of history! Super grateful to be able to participate on stage at Reykjavík Game Summit's inaugural conference 🤩 "Hi from Reykjavík!" 👋

I've been waiting on this one! See how to use our new and immensely powerful GPU profiler in Unreal Engine 5.6+, and how it helps you debug GPU crashes! #uetips www.youtube.com/watch?v=vnbA...

I was not able to make it to Unreal Fest Stockholm, but thanks to @flassari.bsky.social I still ended up on stage! You can find me at 1:50:46 in the video, when I show the Unreal asset browser feature to rotate thumbnails of 3D assets.

We attempted to cram over 100 #uetips into a single presentation at Unreal Fest Stockholm. Did we succeed? Find our right here 👇 www.youtube.com/watch?v=4w0P...

We managed to fill the room at CCP Games for the Reykjavík Unreal Engine Evening, no wonder with those banger presentations 🤩 "Hi from Reykjavík!" 👋

Did that Super Mario Galaxy movie trailer get your nostalgia running? Feel like getting it out of your system by creating something? Why not start with the Custom Gravity tutorial, it will make for a great base for tiny planet hopping! 🌍🏃‍♂️‍➡️🌏 dev.epicgames.com/community/le...

UE 5.7 is out, featuring our new Megaplants plugin: procedural instanced nanite skeletal meshes that voxelize in the distance 👀 @williamfaucher.bsky.social just released a great "getting-started" tutorial on it: www.youtube.com/watch?v=3f7m...

We just released "Unreal Materials: New Features & Productivity Enhancements", where my coworker @shedoesartstuff.bsky.social shows off a bunch of quality-of-life improvements to the Material Editor in UE in 5.6/5.7, alongside new and upcoming features. #uetips www.youtube.com/watch?v=KYmd...

We just published "The Road to 60 fps in The Witcher 4 UE5 Tech Demo", where you can see how we got 300+ moving characters and 100k+ fully modeled trees and scrubs running at 60fps on a base PS5. www.youtube.com/watch?v=ji0H...

A great talk by Alexis Argyriou from Unreal Fest Bali about performant lighting in UE on various hardware. #uetips www.youtube.com/watch?v=Q1wh...

"Getting Started in the Games Industry" is my story of how I entered the game development industry, how I moved from mobile to console games, and how I got my job at Epic Games. With practical advice to the new generation of game makers entering the industry. www.youtube.com/watch?v=Ai3Q...

I had a training session for the speakers of Unreal Fest Orlando on how to speak better, drawing on my own experience fumbling on stage for years. I've now finally made a proper EDC article + video of it so anyone can learn to become a better speaker! dev.epicgames.com/community/le...

I'm so honored to kick off the @wlovegames.bsky.social conference as the keynote speaker ❤️ My talk, "Getting Started in the Games Industry," is a deeply personal story of how I got into the industry, and how that translates into practical lessons for the new generation of game makers.

We just uploaded FORTY NINE presentation recordings from Unreal Fest Bali, and there's some top-notch content in there 🤩 Check them out here 👇 www.youtube.com/playlist?lis...

We've been uploading a bunch of Unreal Fest talks to our Unreal Engine YouTube channel, such as this one from Tanglewood about taking the pain out of engine upgrades 👇 www.youtube.com/watch?v=vMEl...

It was great to open for The Big Screen Gaming summit at Pocket Gamer Connects 🤘 "Hi from Helsinki!"

We've just added an excellent article on optimizing Chaos in Unreal Engine, with lots of engine internals demystified 👀👇 #uetips dev.epicgames.com/community/le...

Game devs in AAA: What are some misconceptions or fun facts about your industry? I'll start: We don't have exclusive learning resources; we're watching the same YouTube presentations and online tutorials as everyone else.

Words cannot describe how happy I am with the standing-room only crowd @mattoztalay.bsky.social and I got for a PROFILING talk! 😲 Huge thanks to Arctic Hazard and Tripwire Interactive for letting us show profiling data from their upcoming game, NORSE: Oath of Blood 🙏 Video recording coming soon!

Sometimes your heroes don't recognize you, and that's OK! Just be chill about it. Don't be like me when I met @timsweeneyepic.bsky.social. He's so famous! Uhm, do as I say, not as I do 😅

One week until Unreal Fest Stockholm! I'm so excited because I heard that Jack Condon will be there 🤩 Hmm, I wonder if I can get him to guest-cameo on stage with me 🤔

Episode 21 of AnsweRED Podcast with Ari Arnbjörnsson, Senior Software Engineer, Developer Relations at Epic Games talks connecting art and programming, how much courage it takes to ask questions, and more! 🎧 YouTube: cdpred.ly/AnsweREDPodc... 🎧 Spotify: cdpred.ly/AnsweREDpodc...

so many devs treat perf this way, like a series of unquantifiable acts of god

Profile.

I couldn't even speak straight when I met the one, the only, the most FAMOUS @highlyspammable.bsky.social ! 🤩 I think he even glanced my way *swoon* ❤️ Unreal Fest Stockholm is SO CLOSE! I can't wait to meet all the cool people there.

Looking forward to seeing some of y’all!

Late to an online meeting again? So embarrassing! A 10-minute default heads-up is way too much time when I just need to join a Zoom. Pro life hack: Go to the calendar settings and set the default notification time to 2 or even zero minutes. Never be late to an online meeting again!

Whoa, I ran into @phyronnaz.bsky.social in Orlando! He made the Voxel Plugin for Unreal! So many cool people to run into at Unreal Fest. And it's only two weeks now until the next one in Stockholm 😯

If you see this dialog in your Unreal Engine project, click Install. At Epic Games, we now ensure that the preferred toolchains for the current engine version are listed in the Visual Studio solution. #uetips

This is how my game dev journey started. When I was 15, I got a trial version of Flash, created this short with my friend on his computer, and submitted it to newgrounds.com. It scored 2.06 out of 5 😄 And now I work at Epic Games! 😮 What ignited your game dev career?

Even though there will be many Epic folks at Unreal Fest, I'm also excited to meet the community people! Like when I ran into @gamedevmicah.bsky.social in Orlando 🤩

Update: The PSOCacheBuster plugin now implements a fix: github.com/Flassari/PSOCacheBuster

Did you know that the Unreal Engine EULA does not mandate you to show the UE logo at the start of your game? If you want to use it, you actually need to ask us for permission to show it. You only need to credit UE in your credits, per unrealengine.com/eula.

⚠️ Driver-cached PSO file extensions recently changed in an Nvidia driver update, meaning that the -ClearPSODriverCache UE startup parameter (and my PSO Cache Buster plugin) does nothing in UE versions older than 5.6 😱 Fix in 🧵

Three weeks until Unreal Fest Stockholm! It's your chance to meet your heroes 🤩 Like when I ran into Ben Board! Most UE licensees have probably interacted with this legend. Indies might have heard of some of the things he's worked on, like Bullfrog games and Fable! 😯

In the latest episode of AnsweRED Podcast, we sat down with Ari Arnbjörnsson from Epic Games to talk about creativity, community, and the connections that push our industry forward. 📃 Read the article here: cdpred.ly/podcast_21_a... 🎬 Watch the full episode on YouTube: cdpred.ly/AnsweREDPodc...

I had a great time on the @cdprojektred.com podcast! We talked about Unreal, sharing knowledge, impostor syndrome, and lots of other topics near and dear to my heart ❤️ Thanks for having me over Sebastian and Pawel!

Less than a month until Unreal Fest Stockholm and I'm so excited! Did you know that Unreal Fests are packed with awesome famous people? I can't believe I got to meet @theunwisetina.bsky.social in person 🤩
