If you want to know how to write performant systems go watch this talk by @slipster216 and follow him. In theory those are computer science 101, yet most of programmers write their code completely against this knowledge for some weird reasons. youtube.com/watch?v=NAVbI1HI…

Practical Optimizations

So with all the talk about optimization happening on Twitter, some ...

I've optimized the hell out of our game rendering \ editor performance over the last month. Turns out that stupidly simple code runs stupidly fast. 😁 Reject Object Oriented cluster*uck Embrace Array

Houdini 20のKarmaでのOCIOを使った際の注意と変更点 - すあまの備忘録

H19.5以前よりOCIOを絡めた設定をちゃんとしておかないといけなくなっているのでちょっと面倒。 原則として、Rendering Working Space=Output Spaceになるワークフローとして話を進めます。 H20はRendering Working SpaceとOutput Spaceが別で設定できる…

Unreal's FOV handling has always been a point of annoyance for me. It's one I understand the legacy of, and one they've finally, sort of, fixed. Unreal used to default to horizontal FOV. This means wider aspect ratios see _less_. Unreal 5 finally defaults to vertical.

My final GDC slides are available here: terathon.com/gdc23_lengyel.p… I was having problems with the vector graphics in the conversion from PPT to PDF. It turns out I could open the whole PDF in Illustrator and manually replace the problematic diagrams.

Replying to @savage309
FWIW, we've found (and Matt Pharr found similarly) that ptex only really performs badly if your renderer's ray differential/mip-map calculations are bad. For us ptex lookups accounts for something like <1% of runtime. pharr.org/matt/blog/2018/07/…

Replying to @lartichauCG
This is completely incorrect. Hyperion was designed around batched shading and out-of-core geometry. Generally we've found ptex perf to only be a problem if ray differentials and mip mapping is implemented poorly; PBRT found the same thing: pharr.org/matt/blog/2018/07/…

If you’re moving to Mastodon, having an app I like made all the difference - it took the frustration out of following people on other servers. – at Oakland, CA

Want to make a visual diagram about SIMD latency hiding on GPU, don't have a clean image just yet but here's a sketch that I had in mind yesterday when was trying to fall asleep
