On January 18, 1982, I joined Atari’s arcade division. I’d dreamed of making games, and they were willing to give me a chance. What a day :-) Today being January 18, 2022, I have somehow reached my 40th anniversary in games... SO thankful, it’s been quite the journey!

WOW, what an adrenaline rush! Thank you Chad Jared Maja @StudioMDHR for letting me finish out my PS4 journey in style. Thankfully I've got two weeks to recover my strength before #PS5 hits!

Our solution to our very active two gamer PS5 household? His-and-hers SSDs :-) Couple of awesome options for 7000MB/s, ended up putting my $$ down on this one. Going to be SWEEET!!!

Cerny Games turns 25 today. Never thought it would last so long, or to take me to such interesting places -- 22 games across all five PlayStations, including a few I (somehow) had a hand in designing Thank you @insomniacgames @Naughty_dog and @PlayStation for the good times!

Hard at work with @jackhuynh, great tech is on the way! @AMD and @PlayStation
From Project Amethyst to a shared vision, I welcomed my good friend and fellow gamer @cerny to Austin, where we reflected on the future that @AMD and @PlayStation are shaping together, the future of gaming.​ Together, we explored the breakthroughs in hardware design, the rise of machine learning-driven experiences, and the innovations that will define the next decade of interactive entertainment:​ 🎮 Neural Arrays – instead of a bunch of compute units working separately, we’ve built a way for them to team up… sharing data and processing together like a single, focused AI engine. This changes the game for neural rendering: bigger ML models, less overhead, more efficiency, and far greater scalability as workloads grow.​ ☀️ Radiance Cores – a new dedicated hardware block designed for unified light transport. It handles ray tracing and path tracing in real time, pushing lighting performance to a whole new level. This lets the GPU focus on what it does best: shading the scene. The result? A cleaner, faster, and more efficient pipeline, built for the next generation of ray-traced games.​ ​ 🧠 Universal Compression – a system that evaluates every piece of data headed to memory, not just textures, and compresses it wherever possible. Only the essential bytes are sent, dramatically reducing memory bandwidth usage. This means the GPU can deliver more detail, higher frame rates, and greater efficiency.​ This isn’t just about technology. It’s about a partnership, a friendship, and a shared journey toward something extraordinary.​ Grateful for the trust, the friendship, and the game-changing future we’re building together.​ 🎥 Watch our full conversation here: piped.video/watch?v=ItXPvGrI…

So excited for the collaboration! Thank you @jackhuynh, looking forward to the journey with AMD
From the same source. Two branches. One vision. My good friend and fellow gamer @cerny and I recently reflected on our shared journey — symbolized by these two pieces of amethyst, split from the same stone. Project Amethyst is a co-engineering effort between @PlayStation and @AMD focused on machine learning-driven graphics and gameplay innovations, built around two core goals: ⚙️ Designing an architecture optimized specifically for machine learning workloads in gaming. 🧠 Developing high-quality neural networks that push the boundaries of real-time game graphics. This isn’t just theory — it’s a co-engineered reality. From hardware breakthroughs to software advances, we’ve delivered smarter, more efficient solutions like Super Resolution in FSR 4, and we’re now paving the way for machine learning based Frame Generation and Ray Regeneration in FSR Redstone. And this is just the beginning. There’s enormous potential ahead, and we’re incredibly proud of what we’ve achieved so far. The future of gaming is bright — and we’re just getting started. Grateful for the partnership, the friendship, and what’s next.

Replying to @JamesStevenson
@JasmesSteveson I agree 100% wholeheartedly with this... but I believe my point was a bit different. Whether it's 60 metacritic or 90, there's ALWAYS takeaways that help me with design of whatever game I'm next involved with. So respect the effort... and learn from it.
