Featuring a new voxel remesher, support for normal generation, several simplification improvements and various optimizations and fixes. GitHub stars and retoots appreciated!<br/><br/>meshoptimizer was started a little over 10 years ago; I&#39;m a couple weeks late but let&#39;s call this an anniversary release.

Then Windows Update installed and rebooted. Today I am testing the same executable and it’s 30% slower.<br/><br/>The executable uses 16 threads on a 16 core 32 thread machine. Today it looks like the scheduler usually schedules two threads per physical core. Settings an affinity mask to exclude odd numbered cores fixes it.<br/><br/>I also never asked for the reboot in the first place. Honestly at this point Windows is a liability. 2026-09-14T21:35:17Z https://njump.me/nevent1qqs8hvv0r2xhy3ykde67j47rfx3wjv52hvj2agdnrmnj3pa4gamzclqzyzz8m794004x3upk8vrjsqjwg0gk2p4z0cwk0wskt3yzlc5ghp7cjdpl5ns In reply to <a href='/nevent1qqsgce73yus802p3hl0r3z9z3ndhxtfwu30wzsa28aah82lsng97vuq7yh4hw'>nevent1q…h4hw</a><br/>_________________________<br/><br/>units are msec, so around a second total 2026-07-28T16:57:20Z https://njump.me/nevent1qqs97mkn6y6z08gql5myw2aqewktvz9etu0uy3ug589l5wp5ajm6jaczyzz8m794004x3upk8vrjsqjwg0gk2p4z0cwk0wskt3yzlc5ghp7cj6v5qkv In reply to <a href='/nevent1qqsgerhc89n4ewneu3nxukrgvk9m22kpefr45jshn2mknt7vgtt39dg0lepfz'>nevent1q…epfz</a><br/>_________________________<br/><br/>Used to take ~15 seconds end to end 😅<br/> <img src="https://cdn.masto.host/mastodongamedevplace/media_attachments/files/116/998/551/591/103/295/original/6c93f3fd649454c3.png"> <br/> 2026-07-28T16:30:30Z https://njump.me/nevent1qqsgerhc89n4ewneu3nxukrgvk9m22kpefr45jshn2mknt7vgtt39dgzyzz8m794004x3upk8vrjsqjwg0gk2p4z0cwk0wskt3yzlc5ghp7cjz8s6sd In reply to <a href='/nevent1qqsgxhc04zj0pxucnrpfy6ar6dn047ne44pqye738f5lg02t8lk4h3gc2p5mm'>nevent1q…p5mm</a><br/>_________________________<br/><br/>Alright whatever I will just merge all textures in an array. 256 textures at 1K resolution is just ~1.4GB VRAM, and VRAM is cheap these days! 2026-07-28T16:22:50Z https://njump.me/nevent1qqsgxhc04zj0pxucnrpfy6ar6dn047ne44pqye738f5lg02t8lk4h3gzyzz8m794004x3upk8vrjsqjwg0gk2p4z0cwk0wskt3yzlc5ghp7cjs99utf There’s still no support for indexing arrays of textures in WebGPU right?<br/><br/>I found that many of my JS perf issues can be worked around by “just” running code on GPU ;) but I need access to textures and it’s difficult to do that with just uniforms… 2026-07-27T21:04:24Z https://njump.me/nevent1qqst8hvy2v2lpzwp4yqvhzjlsecg2w7lwdzx2payx75jfwsee289dqgzyzz8m794004x3upk8vrjsqjwg0gk2p4z0cwk0wskt3yzlc5ghp7cjqk5aqr New blog post!

The loss of personal voice is so striking that it immediately rings alarm bells in my head.

I think it depends on the particulars of your TAA; and also because actual Nanite does micropoly rasterization in compute for small triangles, I would imagine the performance depends on rendered triangle count in a non-trivial way. Note that unlike discrete LOD, under camera motion you’d expect many cluster transitions every frame in different parts of the screen… so single pixel cutoff is much safer. 2025-10-01T18:06:33Z https://njump.me/nevent1qqsw8gs4563hxcyh63f3hg2y9tcu3630d60kkthnuwnwndndpfa5hqqzyzz8m794004x3upk8vrjsqjwg0gk2p4z0cwk0wskt3yzlc5ghp7cjnunrsm New blog post!
