@gregreisdorf I still have the source code for it! I'd do it again too. That handshake led me to my career at Intel and I still work in games 20+ years later.

I founded a game studio… in 2003… A boot-strapped startup with a tiny contract( a hand shake agreement at GDC ) with Intel ($5k) to make an Open GL ES hardware accelerate game on windows mobile for their new device (PDA) they were making with Dell. We made Solterra, a Starfox esk on rails space shooter. It sold 26 copies. I’d do it again.

@iveytron A bit sparse and missing most of the big companies on the expo floor. It seemed like a shift towards indie titles has happened.

Hearing that GDC was a bit… sparse this year. What’s everyone’s experience? First one I haven’t attended in like fifteen years.

@artbyrens No trouble on Intel's end supporting 5.5. github.com/GameTechDev/Xe…

November 12, 2024 UE5.5 comes out of preview.. 4 months.. for these companies to push upscaling so hard you would think it is a priority to enable developers, instead held back from upgrading engine version. With a few weeks to go this comes "right on time", thanks i guess

🚀 New ISPC v1.26.0 Release! 🚀 🔹 Improved ARM support & performance 🔹 New "generic" targets simplify ISPC design & ease new targets support 🔹 Better code generation for x86 & ARM 🔹 Lots of stability fixes github.com/ispc/ispc/rele…

@34pixRed @ispc_updates Alive and well! Devs can use ISPC in their projects just like other source files. We add a bit more goodness every UE release.

@ispc_updates @jeff_rous @jeff_rous Hey there, I just wanted to know about the state of ISPC for UE5

Introducing ISPC v1.19.0! 🎉 * Function Templates! (technical preview) * Support for Sapphire Rapids CPU targets * Support for Intel Data Center GPU Max (Ponte Vecchio) * Improved Arc GPU support. Full Release Notes: github.com/ispc/ispc/rele… 🧵1/6

Intel Open Image Denoise 2.1 is out! It adds support for denoising 1- and 2-channel images, enables mixing data types for input features, improves performance on most discrete GPUs, and fixes several issues: github.com/OpenImageDenoi… #IamIntel

The Intel Software Developer Manual needs to be better organized, more consistent, and have erroneous descriptions fixed. Here is an attempt at revising the instruction listing with refined descriptions logically grouped instead of in alphabetical order. gist.github.com/michaeljclark/…

Just released ISPC v1.21.0! Now with template function specialization support, optimized signed integer overflow rules aligned with C/C++, an enhanced ISPC Runtime, plus numerous stability and performance improvements. github.com/ispc/ispc/rele…

@halogenica Congrats Mike! Looking forward to working with you again!

I’m incredibly excited and humbled to announce I’ve started a new gig today as an Engineering Director at Epic Games!!!

@jon_c_kennedy @pbrubaker @tom_forsyth @omershapira 4090 moved more than you'd expect to CPU bound

@pbrubaker @tom_forsyth @omershapira try running with a better GPU... 😈 😉

Finally got around to reading Matt Pharr's ISPC chronicles. It all looks so clear in retrospect? pharr.org/matt/blog/2018…

@pbrubaker @tom_forsyth @omershapira To those still sitting on the sidelines, why?

@pbrubaker @tom_forsyth @omershapira ISPC code has been run by 500+ million players in Unreal at this point. It has proven its value alongside other industry standard tools such as Clang and MSVC.

Intel's new Raptor Lake architecture (powering the 6GHz Core i9-13900KS and others) is insanely fast. Not just a record clock rate, but I'm also seeing an IPC improvement around 15% over Intel's previous generation in the code I'm running. Wow.

Intel is incredibly excited and honored to partner with Epic Games as a sponsor of MegaGrants. We can’t wait to see what developers create with the power of Lumen, Nanite, and #RayTracing on #IntelArc Graphics!

@psjarlo The ISPC build step is done first to generate the headers C consumes. Then link the ispc and C obj files into the final binary.

@psjarlo Unfortunately not. I started with bare bones C and asm kernel bits and went from there. This is a great resource. wiki.osdev.org/Expanded_Main_…

Since I am heading down the path of adding functionality to my own Libc I think I’ll use ISPC for the memcpy/move stuff just for laughs. Hell, why not.

Benchmarking tips: make yourself a power plan that clamps CPU freq to min/max 99%; this disables turbo boost and generally speaking locks the frequency at base-ish, which helps get more stable measurements (works on desktops!). I've only learned this this year from @rygorous 🤯

@dsuoch I use this for my own tools. Or es as the other replier said for command line.

It would be great to have a CLI to voidtools Everything.
