The state of optimus-manager explained by its developer

I know that dGPUs do scale down, but they don't scale down enough to the point that makes iGPUs totally unneeded. Even with their lowest performance they still draw considerably more power than iGPUs. As far as I know, scaling down is currently limited to lowering down the clock speed and that's it. If they also power down some cores (dGPUs have more cores than iGPUs) I believe they can bring down the power cost to a level close to iGPUs. They will still draw more because of the extra memory (the vRAM), but that won't be a lot and is a cost totally worth it.

Quoting: nwildnerQuoting: sarmadI have always said it: hybrid graphics is a bad design to begin with and should have never been adopted by anyone. It complicates the hardware, complicates the software, and it also wastes space on the chipset. Complexity results in bugs, and anyone who has used hybrid graphics knows how clunky the concept is.
A fraction of the efforts spent by all parties on getting hybrid graphics to work could have instead been used to actually enable dGPUs to scale down their performance when it's not needed. We could've had dGPUs that can scale down their power consumption to a point close to those of iGPUs when no game is running (lower the frequency even more, power down some of the cores, etc).
Agreed on laptops going full dGPU here, and ditching off the iGPU
When I was using a Muxless laptop 3 years ago, I've made some simple tests and configuring Reverse PRIME to start all X on the dedicated GPU entirely, and I was astonished with the results. Setting the dGPU from the ground up as the provided made my system perform better and drain less battery than using the iGPU or the dGPU through "prime-run" even without a mux switch in place.
My current Laptop does not have the BIOS option to set the dGPU only, but I know Lenovo Legion allows it.
The part that I disagree is with the fact that dGPUs don't scale down power on laptops and that is untrue. Here are some tests with optimus-manager set to "Nvidia"(power cord plugged)

nvidia-powerd needs to be enabled for power scaling to work.

NVIDIA DLSS 3.5 and Half-Life 2 RTX announced

Because it's using RTX Remix, which is a tool nVidia built specifically for DX9 (Yes, only DX9, not DX10 or above, not Vulkan, not OpenGL). It sits between DX9 and the driver and on the fly replaces commands/assets with RTX enabled ones. It's designed to enable adding RTX to retro games WITHOUT touching the game's code. So the game having a Linux port doesn't matter because they are not actually touching the game's code at all.

Quoting: Linux_RocksMan, Quake II RTX has native Linux support. Why can't this or Portal? Half-Life 2 and Portal already have native Linux versions. I don't know how modding works internally. But doesn't that automatically help make it possible? </3

Ratchet & Clank: Rift Apart is Steam Deck Verified and out today

Yeah, as I expected. The portal jumps cannot possibly be seamless on the Deck. But having stable 30 fps is great to hear, that should make it perfectly playable, especially on a small screen.

Quoting: EgonautQuoting: PenglingAfter all, the specs look pretty reasonable, aside from the massive 75GB of storage that's required for it!I don't know where that 75GB come from, it only consumes 39GB here.
Quoting: F.UltraSo this being the first game to use DirectStorage 1.2 that all the Windows fanbois are up in arms about so will be interesting to see how loading times will be in WINE/Proton here vs native Windows.
DirectStorage works with Wine/Proton as well. On my PC with a PCIe4 SSD the Portal jumps are pretty seamless. On the Deck not so much. Can take up to 3 seconds.
Quoting: sarmadYeah, I'm interested to see how this performs on the Deck. I doubt it'll be as seamless as it is on PS5.It runs at pretty stable 30 FPS on lowest settings with FSR. It's playable, if you really want to play it on the Deck.

Quoting: TheRiddickMight be stutters in areas where you transition levels since it was designed around much faster NVMe speeds (with special Sony compression on top which sped things up further)

Linux hit over 3% desktop user share according to Statcounter
17 July 2023 at 7:24 am UTC Likes: 4
SteamDeck was at 1 million last year, the number is probably above 2 millions by now, but SteamDeck is unlikely to contribute to Statcounter, i.e. the report from Statcounter is excluding most of SteamDecks. This is because Statcounter depends on visited web sites and my guess is that SteamDeck users spend the vast majority of their time playing games rather than browsing web sites.

My guess is that the Uknown OS is someone using a browser extension that hides their details, or maybe some proxy or vpn.

The Linux origin country Finland was almost 11% a year ago too. Maybe the actual truth slipped through accidentally for a short moment? What is that Unknown operating system anyways globally? It if often very high up there.
