Anyone else having an issue with the performance of Steam games after updating to Tahoe? I'm getting 25fps in Cyberpunk and 40 for Combat Master. I'm on a M4 Max Studio with 64gb and have 1gb up/down on internet. I'm going to try some App Store games and see if the performance has dropped like the Steam titles.
Got a tip for us?

Don't know if it's the same for you, but I noticed after upgrading to Tahoe, and getting the latest Steam client update, just opening Steam, and doing nothing else, gets my macbook extremely hot. I checked and the CPU is being used over 60% constantly and reaches over 70 degrees Celsius.
Close the Steam window. Electron based apps like Steam override a private method that cause slowdowns on macOS 26. So until Steam is updated (ahaha, that's going to be a long time, maybe try the beta), or macOS adds a workaround (probably not), things are going to be slow the more you keep the Steam window open.

Steam is not an Electron app (though it does use the Chromium engine like Electron apps do).
In any case, regarding Electron apps, since this is an identifiable performance regression, it seems like something that Apple "should" fix.

The performance regression is a result of using private apis. It should be fixed by whoever is doing that.
