I don't think people realize how incredible it is that a movie rendered in nearly real-time in free software on a single computer just won the Oscar for best animated film. If there was ever any proof you don't need AI, this is it.
Flow was made entirely with Blender and rendered in real time with EEVEE. We didn't use a renderfarm. The final render was done on my PC. There was no compositing, all the colors were tweaked and adjusted using shaders.

It is easier to GIVE UP performance than to RECLAIM performance. “Don’t prematurely optimize” statements are nonsense. Proper guide: don’t give up performance prematurely. As such building systems (not scripts or simple tools) in slow languages (C#, Python) is likely a mistake.

The Chosen One ventured to strange new places in their quest to save Arroyo. From the decadence of New Reno, to the ordered streets of NCR, and the advanced facilities of the malevolent Enclave. Today we wish a happy 26th anniversary to #Fallout 2!

It's been 27 years since we first left the rat-infested caves that hid Vault 13, resolved the quarrels of Junktown, aided the metallic monks of Lost Hills, and infiltrated the Cathedral from where the Master enacted his grand plan. Happy anniversary to #Fallout!

Let's talk about CPU scaling in games. On recent AMD CPUs, most games run better on single CCD 8 core model. 16 cores doesn't improve performance. Also Zen 5 was only 3% faster in games, while 17% faster in Linux server. Why? What can we do to make games scale? Thread...

This is amazing! I wish I could have worked on this demo. Just so cool. Hats off to everyone who did. 1000s of dynamic shadow casting lights in real-time on a PS5! youtu.be/KYGEfQJPqW8?t=3062

We are Mega excited about this in particular 🔦 MegaLights, a new experiential feature in 5.5, enables artists to use orders of magnitude more lights. They are movable and dynamic, with realistic area shadows, and can light volumetric fog. See this capture of our live, real-time demo using Quixel Megascans and KitBash3D assets. #UnrealFest

code duplication is actually not bad It can decouple things. It's easy to reason about. 9 times out of 10 it's better than whatever idiotic abstraction we build to avoid it.

I will say it again to all IHVs: Please implement fence sync support between GPU/NPU and make sure NPU can read GPU-swizzled / framebuffer compressed (lossless) textures. Otherwise NPU will be useless for graphics tasks such as neural upscaling.

The single most important thing I have learned about software development over my career is that if you do not aggressively fight complexity, it will eat you alive.
