@flassari
Senior Software Engineer, Developer Relations at Epic Games. Former Lead Programmer on #Returnal for #PS5 @Housemarque. for my presentations!
Had a great panel on "Optimizing Optimization" with Ken Noland, Simon Barrat, and Dan Wood at @developconference.com. "Hi from Brighton!" 👋
Had a great time in England teaching the Brits about frame pacing and input latency in Unreal. "Hi from Brighton!" 👋
Super happy with a full room of devs interested in improving frame pacing and input latency in their games at Unreal Fest 🙌 "Hi from Chicago!" 👋
Polly the Profiling Parrot helped me and Captain @mattoztalay.bsky.social realize that the true treasures are well optimized games! Hi from Chicago! 👋🦜🏴☠️
Hey, Captain @mattoztalay.bsky.social! I just traded our pirate ship for this magical parrot that should be able to lead us to amazing riches! What a bargain! Apparently, we're supposed to find the treasure at something called "Unreal Fest Chicago" next week.
This week marks my five-year anniversary at Epic Games! 🎉 Thank you to my lovely coworkers and to all the UE devs out there who make my job such a blast! Keep making amazing games everyone! 🤘
I keep seeing people using the old UE logo to advertise their game/product. We updated it quite a while ago (the U is rounder now.) You can just download the high-res logo from unrealengine.com/branding, don't get it from Google Images 😬
That's how you get zero stutters in your game. You're welcome, game industry. #uetips
Super early birds get the worms. The discount worms 🪱 200 worms! Or I mean, they get to not have those worms. Uhm... Anyway, cheap tickets! 😅 Super-early bird pricing at $200 off for Unreal Fest Chicago are now available: unrealengine.com/events/unreal-fest-chicago-2026
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.
Unreal Fest 2026 is coming to Chicago next June, and I want YOU to present there! Call for proposals is open until January 22nd, speakers get free hotel accommodation and conference tickets 🤘 Apply here: unrealengine.com/news/apply-to-present-at-unreal-fest-chicago-2026 I hope to see you there!
"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
Wow, perfect timing! I was just writing up some info on that internally for my teammates 😄 See image. The link goes here: dev.epicgames.com/documentatio...
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!" 👋
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...
Bring The Great Hitch Hunt to your Halloween party with this karaoke version of "Kill the Hitch!" 🏹 YouTube: youtu.be/T8xX7BsgURI Download: epicgames.box.com/v/HitchHuntKaraoke
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.
It was great to open for The Big Screen Gaming summit at Pocket Gamer Connects 🤘 "Hi from Helsinki!"
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 🤔
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.
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 😯
