What if it hits around 90°C during Vulkan shader processing? 😅 Otherwise like 42–52 idle. How's that? I'm wondering if my cooling is sufficient.
This is an AMD 9950X3D + 9070 XT setup, for reference.
Any way to do Vulkan shader processing on the GPU perhaps, to speed it up?
It's fine, modern CPUs boost until they either hit amperage, voltage, or thermal constraints, assuming the motherboard isn't behaving badly then the upper limits for all of those are safe to be at perpetually.
If you're talking about the Steam feature you can safely turn it off, any modern hardware running mesa radv (the default AMD vulkan driver in most distros) should be sufficient to process shaders in real-time thanks to ACO.
What does it mean to "process shaders in real-time"? Wouldn't it be objectively faster to process them ahead-of-time? Even if it's only slightly faster while running the game?
I mean processing takes like a minute or so, so it's no big deal. I'm just curious for the fun of it, if I can compile it on the GPU. Not sure it's even possible.
Processing them as they're loaded, quickly enough that there's no noticeable frame drop. Usual LLVM based shader compilers aren't fast enough for that but ACO is specifically written to compile shaders for AMD GPUs and makes this feasible.
Pre-compilation would in theory always yield higher 1% lows yes, but it's not really worth the time hit anymore especially for games that constantly require a new cache to be built or have really long compilation times.
I think the one additional thing Steam does in that step is transcoding videos so they can be played back with Proton's codec set but using something like Proton-GE, Proton-cachyos or Proton-EM solves this too.
Disclaimer: I don't know how the deeply technical stuff of this works so this might not be exact.
Huh.
Well like I said it only takes like a minute with half of my 32 threads utilized at 100 % (so all of my cores I guess?). Might as well keep doing it I suppose.
How far back does that go? My AMD 6000 series GPU probably doesn't need it, but what about my old laptop APU (3500U?).
AMDs 7000 series CPUs were designed to boost until they hit 95c, then maintain those temps. 9000 series behaves differently for boosting, but the silicon can handle it.
Okay cool, then I feel more confident. This is only my second build, ever, so I'm a little bit nervous. I didn't buy any extra fans apart from the ones that came with my case. But I did get that beasty Noctua gen 2 air cooler, and it seems to be holding so far, even in the hot summer air.
