but the whole steam client? has always been vgui, not electron cef. just because there is reference to chromium in the commit log doesn’t mean the whole thing’s built in chromium.
The “whole client” hasn’t been VGUI. Yes now every element is CEF but many, many pieces have been CEF for a very long time. “Switched over to Electron” implies it was entirely changed but it’s just using more of the thing it was already using. Those are two different things.
it’s not just me who has performance issues. at one point it was everyone on linux with an nvidia gpu
The issue you linked had nothing to do with Steam it was a bug with the Nvidia driver itself. Not sure what that’s supposed to prove.
my point was that i never had issues with vgui, and now i do.
And my point is that is not an inherent problem with Steam, that is something specific to your configuration. If it runs fine for other people it can run fine for you. I’m on Arch with an Nvidia GPU. I have zero issues with the performance.
