Software Engineer at Oculus. Mostly I optimize code, CPU and GPU.

@MassieforKY @justinamash You should run as a 3rd party candidate in the general

[Eric Duhon @duhonedd]

Maybe a compromise. Positions stay available for hardware vert fetch. Rest change to load. Since positions probably benefit the most from hardware fetch, binning pass. I'd be curious to see a performance comparison on Adreno. If hit is small enough, I might take the simplicity instead. Especially since adreno will dump the fetch units at some point anyway, if they haven't already in 800 or newer

[Eric Duhon @duhonedd]

@SebAaltonen @bertvdbosch5 As of at least 700 series adreno, they still have hardware vertex fetch. And given the vert shader has to be run more than once on tiled hardware... Sure would be nice though, I'd be curious how much of a hit it is on adreno. I'm not sure if any changes in 800+

@Jonathan_Blow If only they had made the edram just a bit larger. Was a pita. Like a mobile gpu, but only 2 tiles.

@lemire Unavoidable as long as everyone has a different opinion on what good code looks like.

[Eric Duhon @duhonedd]

whats worse, I don't think the wasted cycles are even making it easier or cheaper. instead, what a small team of 5 used to do, now takes 100 people. If modern techniques had improved productivity 100x, that would have been a good argument for them. I understand though, I have fallen into the overengineering trap myself a few times, the struggle is real.

I upgrade my desktop every 8 years these days lol. Although I do usually do a 4 year midlife cpu swap(AMD motherboards have a long shelf life), and a gpu upgrade. maybe 6 years for laptop. I remember upgrading from a 386sx-25 to a 486dx2-66. I like to see a real jump when I upgrade, not just a measly 2x.

Past time to start paying a dividend. Tsla is a purely speculative asset at the moment. Why I sold all mine, with a dividend I wouldn't care so much about the stock price . Plus my vote didn't count anyway, I already voted for your pay package before, when I owned some tsla directly.

@pcgamer Ultima 7 and Tie Fighter are missing.

@elonmusk This tech is going to be great for small indie games!

[Eric Duhon @duhonedd]

@NSFVoyager2 @ProfBrianCox Past time for another voyager. How fast could we get to 1 light day with today's tech(upcoming rockets)? Get there with all instruments fully powered. Still need 4 more voyagers anyway, 6 has a destiny!

@DividendGrowth FOMO is deadly

@skdh dang, I was hoping it was going to be a 100-year minimum, buy us some time on global warming.

Compare 3D models using traditional KTX2 textures (UASTC/ETC1S) vs AVIF + Spark to see the benefits of real-time texture compression in web apps.

@lexfridman Insane world. So much different than 30 years ago

@mackron I just recently stumbled upon it. Liking it so far! Switching my homegrown WASAPI only library over to miniaudio. This reminds me, I need to star it.

64KB pages caused me some hassle in PS3 days. memory fragmentation. 16KB does seem like the sweet spot. Although with modern memory sizes, 64KB probably fine too. wish they would add something in between 4KB and 2MB in x64. probably have to wait 15 years from time it was added to x64 before you could use it.
