I don’t like blocking anyone on Twitter. Everyone is entitled to their opinions and I don’t really like to dictate how they can or cannot express those opinions, or what channels they can use to give me feedback.

Best analysis I’ve seen of subtick movement here, worth a read if you have concerns about movement. reddit.com/r/GlobalOffensive…

Most (but not all!) of the problems around subtick movement right now stem from cl_showpos not understanding subtick. It reports values on tick boundaries which makes them look inconsistent—because of course they do! The movement curves have been shifted to offset from a tick.

This is how I call it. Oh no am I calling it wrong in my games?

I do not follow college football, but I am watching the huskies play Stanford now and I have a couple questions: - how can a team be 7-0 but ranked 5th? - how can a team that is 7-0 struggle so much against a team that is 2-5?

100% this. This may matter, but it may absolutely not matter at all.

I will surely regret this; let’s do it anyways. I’ve worked on performance in video games for almost my entire career (two decades now!) This thread is how I personally think about perf. 🧵

If you are getting 1000 fps but you drop 30 fps (to 970), that is much less bad than someone who gets 31 fps and drops 30 fps to 1 fps. (Or said correctly: going from 1 ms per frame to 1.03 ms per frame is less bad than going from 32.2 ms per frame to 1000 ms per frame).

That’s it. Thanks for coming to my TED talk on how I, personally, think about performance.
