I have played this on PS5. So much fun. Highly recommended.
Glad to see it work well on the Deck.

Linux continues rising above 3% desktop user share on Statcounter

Quoting: mitcoesIt will be 6.52% Linux soon, as Chrome OS is going to switch to Wayland
Since when has using Wayland 100% of the time been a requirement to be a Linux distribution? If we went by that standard SteamOS, or a lot of people still using X wouldn't count as "Linux" either.

ChromeOS is already a Linux distribution, all that is happening is it modernizing and moving closer to the rest of the ecosystem. We need to stop splitting Linux apart over relatively minor differences.

Since, forever? To be a GNU/Linux distro the distro would need to support the stacks that Linux binaries would require to run. This includes either X11 or Wayland. Chrome OS currently uses neither of these two, which is why Linux apps in ChromeOS run via a VM and cannot run natively. If ChromeOS does indeed switch from Freon (the currently used display server/protocol) to Wayland it means we should be able to run Linux binaries natively on ChromeOS. Additionally, if ChromeOS switches to Wayland it means it'll have to rebuild it's Android compatibility layer work with Wayland, which hopefully means we can probably get that running on other distros.

Quoting: 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.

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.

NVIDIA DLSS 3.5 and Half-Life 2 RTX announced
23 August 2023 at 6:47 pm UTC Likes: 2

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

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.

Lots of zombies in this bundle. Glad to see most of it playable.

Quoting: Egonaut
Quoting: 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.

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: 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)

Yeah, I'm interested to see how this performs on the Deck. I doubt it'll be as seamless as it is on PS5.
