Steam Set Up - Newcommer

Hey guys,

I just installed Bazzite alongside Windows, coming from Zorin OS.

So far, I got everything set up. One thing, which is really annoying me, is the Steam seems to be very slow for me.

  • If I start a game, e.g. Witcher 3, it takes up to one minute to start the game at all.

  • If I right click on a game on Steam for example, it takes up to 3 seconds to open the window.

  • Got also a weird bug that when I right click on a certian game “Foundation”, Steam crashes. Only happens with this game.

Already tried ujust fix-reset-steam but it doesnt seem to change anything.

Moreover I am getting this error: ERROR: ld.so: object '/usr/lib/extest/libextest.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

Can anybody help me with that?

Thanks for any help!

Not sure about the error yet, but first let’s make sure shader pre-caching setting is off in steam.

Steam has this as a default setting, but it is probably no longer necessary as shader compilation is now handled mostly in-game similar to Windows now. Otherwise your computer will try to load the entire game’s shaders all at once before launching the game…this is both time consuming and may cause instability due to high resource utilization.

Look under steam’s settings and find the options that match the image below…needless to say turn both of these settings to off.

You may also want to turn off cloud sync globally in settings and then use the steam game properties menu to manually enable for games that you need it for. Keep in mind that not all games provide cloud sync in ready working order. It slows down various things to have that setting on (unless it is needed).
