@shivoa :shrug: :)
@shivoa ohh, 2500K, yeah indeed time for an upgrade. My GPU impl might be "suboptimal" for nvidia, I guess (structured buffer usage perhaps?). On the Mac I'm also getting better results from Intel than from NV.
Daily Pathtracer part 10: small update to have all implementations on the same page again; and a note on Mono C# performance tweaks. http://aras-p.info/blog/2018/04/16/Daily-Pathtracer-10-Update-CsharpGPU/
Next up: let's do a stream/buffers oriented path tracer setup! (why? I don't know)
@KeefJudge windows phone. whoa! :)
Daily Pathtracer part 9: a wild ryg appears and optimizes my code! http://aras-p.info/blog/2018/04/13/Daily-Pathtracer-9-A-wild-ryg-appears/
Next up: put these optimizations into C#, C#/Burst, GPU implementations.
@KeefJudge I saw someone mention https://pinafore.social/ as an alternative web client, haven't tried it
@KeefJudge I mean, mastodon client (and server) source is on github. If you manage to land changes into official release, they will appear here eventually too :)
I blogged about compilation time – compiling with -std=c++98 is (sometimes) much faster than -std=c++11

@KeefJudge it's open source! which means... I dunno, maybe, if it breaks you can keep both pieces :)
Daily Pathtracer part 8, where I'm learning more SIMD, and add more spheres to the test scene. http://aras-p.info/blog/2018/04/11/Daily-Pathtracer-8-SSE-HitSpheres/
@zenmumbler "the thing about internet is, no one knows you're a dog" -- I could have said I'm an expert on SIMD and there's no way to verify that :)
I do know some people who, for exact same amount of experience, would say that they are experts...
Daily Pathtracer is back! Part 7, where I'm learning about SIMD. http://aras-p.info/blog/2018/04/10/Daily-Pathtracer-Part-7-Initial-SIMD/
Next up: more SIMD.

Daily Pathtracer, Part 6. DX11/HLSL implementation (still not optimized whatsoever). http://aras-p.info/blog/2018/04/04/Daily-Pathtracer-Part-6-D3D11-GPU/
Next up: will do a break for a couple days; sustaining daily posts is hard :)
@ScreennameTaken in my experience it just is (on some other workloads too). According to the internets, it can do more "math" indeed (Intel Iris Pro: 832 Gflops, GeForce GT 750M: 722 Gflops). It doesn't have that much memory bandwidth, so YMMV.
@jakob meh, that sounds like work. I don't like work :)
@jakob that's my takeaway from other benchmarks too; the Intel one is actually *better* at computing power, it only is slower if bottlenecked by memory bandwidth
@groud too hard for me
