@m4zas24 @imanands @threejs Unreal Engine 5 does work in a browser, using WebGPU x.com/AlexStLouis10/…

@imanands @threejs I would agree with the progress in webgpu but In my opinion there is anything yet to be seen like Unity blender or unreal that works in browser, I mean rendering animation would be too consuming but 3d modelling similar to blender would be very nice

The game engine monopoly is ending and most people haven't noticed. In the past week alone: 16k-strand hair simulation running in a browser tab via #WebGPU compute shaders. A full 3D endless runner built with zero external assets — just @threejs primitives and Web Audio API, fitting in a single HTML file. Terrain systems, procedural worlds, real-time physics — all browser-native. These aren't demos. They're signals. The assumption that "serious 3D = download a native app" made sense when browsers couldn't handle complex rendering. That assumption is now wrong. The next generation of game engines won't ship as 2GB desktop installers. They'll run in a tab. And the games they produce will be URLs, not .exe files. #gamedev #indiedev #buildinpublic

@UnrealSensei @mattworkman @UnrealSensei sent you a DM

@UnrealSensei @mattworkman @UnrealSensei we're bringing it back for UE5 but with a twist... we upgraded the rendering to WebGPU to enable compute shaders. Would love to give you a demo! We even got the Lya demo running in browser. x.com/AlexStLouis10/…

if one were to be building an AI first gaming platform, it needs to FIRST be iOS native and work REALLY well like as close to a native Swift app as possible with all of the hardware hooks. And 2 have browser capability. This lends itself more to 2D flash style games. I see what my kids and their friends play and it’s Roblox but then a lot of obscure 2D games and Subway surfer etc. I still see AI in game design as basically a shippable working game framework that Claude can seamlessly edit from prompts without breaking it. And of course one click generate most of the base visuals. This would be easier with 2D games. I feel like Unity is so close to this already but it feels half old and not enough new. If investors could be convinced there was any money in games in 2026, a new start up in the garage could make some waves. But trad artists and game devs are so anti AI it will have to come from the new generation or an outsider.

New website for SimplyStream is live! If you have an Unreal Engine 5 game or project you want to bring to the browser leveraging WebGPU and WASM, please visit our website below or send me a DM. #WebGPU #ue5 simplystream.com

@OverdrawGames @OverdrawGames Very nice! Any interest in bringing this game to the web? My team built out WebGPU support for UE5

@AlexStLouis10 Unreal with some custom tech that allows for so many entities on screen at once

I'm trying to build the best looking survivors game by myself. I've poured 3 years of my life into handcrafting every asset to be a feast for the eyes. I hope you'll love this game as much as I love developing it. Please consider wishlisting Resistance Is Brutal if you like what you see! -> store.steampowered.com/app/3378140/Re… #screenshotsaturday #indiedev #gamedev #indiegame

@borgetsebastien @facbros @borgetsebastien you can have the best of both worlds with near native performance + web availability. My team built out WebGPU support for Unreal Engine 5. Lmk if there's interest in trying it out for NEXT! simplystream.com

@facbros Unreal engine delivers better native performance than WebGL / browser based experiences for now, but there is still an accessibility trade-off. We showcased 3 experiences in Alpha Season 7 made with the same web tech and the gap is obvious. WebGPU might change this in the future

@borgetsebastien I think The Sandbox's quality is better. NEXT📱👍

We are making the power of real-time 3D more accessible 🌐 We’re getting ready to officially launch Unity Studio, our web-based editor designed for industries like manufacturing, automotive, healthcare, architecture, and more to build, interact and iterate in 3D easily. In the meantime, our Open Beta is active right now. Get in early, explore the interface, and start building before the official GA rollout. Start building in your browser: on.unity.com/unitystudio #UnityStudio #UnityIndustry

@asha_shar @asha_shar really exciting, because this means the next Xbox would support web games as well, which is a space my company operates in and builds developer tooling for. Sent you a DM!

Great start to the morning with Team Xbox, where we talked about our commitment to the return of Xbox including Project Helix, the code name for our next generation console. Project Helix will lead in performance and play your Xbox and PC games. Looking forward to chatting about this more with partners and studios at my first GDC next week!

@Thunder_Owl @SeloSlav @Thunder_Owl Agreed! Indeed they are fantastic assets - all credit goes to the creator from the Fab marketplace. Our team simply compiled and deployed it to the browser using our WebGPU tools, and optimized it.

@AlexStLouis10 @SeloSlav Familiar assets 🙂 (no, not mine, just well known)

Web gaming is about to get very big. Within the next couple of years we will likely see a new “Newgrounds-style” ecosystem emerge. A web-native distribution layer for games that competes with platforms like Steam. There will be plenty of low-quality content at first, but the best projects will rise quickly, just like they did in the early internet era. Several trends are converging at the same time. WebGL and browser graphics are improving rapidly. Advanced shaders, GPU pipelines, and even server-side rendering make it possible to stream sophisticated visuals without requiring a powerful GPU on the player’s machine. At the same time, developers are increasingly frustrated with traditional distribution. Shipping to Steam means surrendering roughly 30 percent of revenue and operating within a closed ecosystem. The web offers a path to direct distribution and ownership. But there’s something more interesting going on. Games are becoming large-scale simulations. At their core they are agent-based models (ABMs), which are just systems where thousands or millions of actors interact according to rules and generate emergent outcomes. This is an area researchers have been exploring for decades, especially institutions like the Santa Fe Institute. Now these same ideas are colliding with modern AI and massive compute. The result will be a new kind of platform where games double as large-scale simulations of economics, warfare, industrial systems, and social behavior. Mass-scale agent orchestration inside persistent worlds creates enormous datasets for strategy, game theory, and machine learning. The intersection between gaming, AI, and simulation may end up being one of the most valuable technological frontiers of the next decade.

@SeloSlav Thanks, we're raising more money atm if you're interested. Feel free to DM

@AlexStLouis10 This is insane!!! Great job

@iBrews @iBrews I wonder if Openclaw could do game porting..

Here’s some of the messages Sam and I exchanged in slack:

@asha_shar @XboxP3 @asha_shar @jronald Xbox next-gen design inspiration, featuring nostalgic callback to the original Xbox's colors and the nod to it being a gaming PC + console hybrid. @Colteastwood thoughts?

Today Matt and I had the chance to recognize @XboxP3. Over the past couple of months, we’ve talked nearly every day about everything from hardware and strategy to creators and culture… and plenty about our kids and dogs, too. Those conversations gave me a front row seat to what so many of you have known for decades. Phil is a remarkable leader, but even more than that, he’s a deeply remarkable human being. When he took over @Xbox in 2014, it was a pivotal moment. He pushed for backward compatibility because players asked for it. He helped bring Xbox One X to life. He created Game Pass. And through it all, he re-centered our decisions around players and creators. A lot of careers get summed up by milestones. Phil’s impact shows up in stories. In the creators who felt safe taking risks, in the teams who did the best work of their lives because someone believed in them, and in players across generations who felt like Xbox was theirs. I’ll always remember this day. I’m proud to be part of Team Xbox. Now our journey begins 💚

@asha_shar Long time Xbox gamer here. The Curse of Monkey Island, Assassin's Creed 2, and the original Dead Rising. Btw, my startup works in gaming devtools and we have some asset chunking tech that could help Xbox slash install speeds substantially, to allow players to play instantly. Would love to chat!

Top 3 greatest games ever? Why? GO👇

@Tooley1998 @Tooley1998 Game looks amazing! Definitely going to buy. What version of UE5 is the game using? We can help you port it to WebGPU if it's on 5.6 or 5.7

Lay of the Land will be available April 8th on Steam! Wishlist the game here: store.steampowered.com/app/2776090 Watch the gameplay trailer:

@deedydas nice work! Does it use WebGL or WebGPU for rendering? I built Vibecraft, a vibe coded voxel RPG using Gemini 3.1 pro. I added CAGI (Cellular Automata Global Illumination) so it's WebGPU powered RT that runs on low end hardware. This is less than a few hours work btw: x.com/AlexStLouis10/…

Wow, Gemini 3.1 Pro just crushed one of my test problems no other model could solve. "Write a photorealistic 3D ocean simulation" 3D graphics is extremely hard. It has to encode 9-10 techniques based in physics. Being off by just 1 number can lead to bonkers results

@ballmatthew @ballmatthew Matt, I didn't see anything in your deck about browser gaming? What are your thoughts on the size and growth of this market, especially as it's growing faster than other gaming verticals? pocketgamer.biz/more-than-1500…

I vibe coded a browser-based, WebGPU voxel RPG in the browser using Gemini 3.1 Pro! Uses three.js for the rendering framework. @vibecoding #gamedevelopment Link to play: …95fumikmn-d2df3109.us2.manus.computer
