If you use Chrome and have upgraded to macOS Tahoe, disable "experimental prediction for scroll events" at chrome://flags to make it not feel like you just downgraded to a RAM-starved Windows 98 PC. (Thank you, @jespervega!)

@patrickc @jespervega Likewise, turn off Apple “Intelligence” in the System Settings… all of a sudden apps start opening lightning fast again!

@patrickc @jespervega Ah yeah I think they rearced the scroll pipeline for tahoe for 120 fps screens as a whole — imagine it’s either draining more resources and polling 2-4x as much as usual since it’s reading vsync time or it’s polling 1/2 as much as it should and acting like it’s 60fps

@patrickc @jespervega There’s some serious irony to a feature meant to improve perceived scroll performance causing lag

@patrickc @jespervega I was literally about to file a bug report for this, you just saved me hours of frustration. What a bizarre default setting.

@patrickc @jespervega lol it instantly feels so much faster wtf

@patrickc @jespervega Who still uses chrome?

@patrickc @jespervega PC out here dropping knowledge. You still can't skip a trial on Stripe as a customer... but at least the founder is practical.

@patrickc @jespervega oh my god I'm a luddite now

@patrickc @jespervega thank you so much

@patrickc @jespervega Omg thank you

@patrickc @jespervega lucky i did not upgrade to Tahoe. Seem like a big mess

@patrickc @jespervega Is that a function for the new AI Chrome that will scroll content endlessly?

@patrickc @jespervega Switch the logo back!

@patrickc @jespervega More tips please.

@patrickc @jespervega That would explain how clunky Chrome felt today!

@patrickc @jespervega duuuude holy. i've been so frustrated with how janky it felt.

@patrickc @jespervega Haha, Patrick, great tip! Turning off that scroll prediction on Chrome really saves macOS Tahoe from a full Windows 98 meltdown!
