For the past few months or so, steam precaching has been out of control. I have to download between 10 and 30 GB of shader precache data per day. That is extremely ridiculous. Steam’s shader caches are quite often almost as large as the game itself. For example: the image here is a game that is ~7GB for the full game, downloading 10GB of shader precache. If I download an average of 30GB of shaders per day, then that is almost 1TB of data downloaded written per month just in shaders…
Not to mention that games I play regularly like CS2 get a precache update literally every 2 days that is 5-10GB and if I manage to cancel it, there is 0 difference in performance at all.
Also fossilize replay that takes 20%-50% CPU load, sometimes for an hour and is the single highest user of disk IO on my entire system. I would be concerned about SSD wear if it was during the early times of ssd just because of the massive amount of writes.
I’m all for downloading shader precaching, but at normal intervals of after updates, not just randomly every few days when there hasn’t been a game update in months or years. I don’t want to delete all of my games because I only have 100/30 internet, so it would take me a long time too redownload games.
Has anyone else been seeing these ridiculous intervals and datasets of shader cache? Could there at least be a selective pre-caching setting only for games that I play regularly so I am not caching shaders for games that I haven’t played in 2 years?
Same issues here, opening steam each night greets me with every single game downloading 500 mb - 5 gb of shader updates. It’s insane. I don’t get why my steamdeck doesn’t do this but an Arch desktop does?
It doesn’t? My deck has shader updates for nearly every installed game every time I touch it.
Same here
I get a few, but not every single game like my desktop does.
It should update about when you get a new driver version. I’m using your desktop gets more frequent updates than your Steam Deck.
Whenever I install updates on my Steam Deck, I get a bunch of shader updates.
My Deck and Linux desktop regularly have shader cache updates every few days, but they’re generally tiny and finish near-instantly. I’ve never seen the behavior here of needing to download multiple gigabytes of shaders daily (and I’m thankful for it, with the frustrating data cap I have from my ISP).
On arch you can just turn shader caching off, the newer mesa versions cache the shaders in the background, you don’t need steams thing anymore Edit: spelling
