Have been messing around with co-op for local LAN play across PC and console (PS5 Pro) and noticed some random things which were interesting, especially while I have the PC one modded and of course the PS5 Pro one is not modded

- Playing fidelity vs performance on PS5 Pro, the fidelity seems basically negligibly different to me in visual quality, besides a little bit of the helmet reflection, so using performance seems like a total no brainer as the FPS is way, way better in that mode, seems like PSSR2 is more than enough to make it look sharp enough honestly from performance mode

- Using several mods on the PC version has not impacted being able to play in co-op with my PS5 Pro version at all so far, though I haven't tried every level or every game situation yet, it seems like it doesn't have an issue working together

- When using the weapon mods on the PC version while playing co-op, it seems the weapon stuff is all done client side, so while the PC player can get different weapon behaviours, the PS5 Pro one just sticks to the same default weapon behaviours e.g. using 60 clip on the MA5B rifle only applies it to the modded PC player

- Also if you use mods such as that 60 clip MA5B, when either player from the PC or PS5 Pro reloads, on the PC player screen it will show the AR reload in-game as 60, and it will show everyone's reloaded MA5B on the PS5 Pro side as 32, no matter what the full clip for either player actually is, and if it hits 0 on either screen, it just stays at 0, no negative numbers

- If you shoot the MA5B a bit, and it is at say 45 rounds left, if you toss it on the ground (using hold down dpad), it will still say 45, but the compass for the weapon on the ground only shows up direction

- If you look at the co-op partner's MA5B, the only direction on the compass ever shown is up on the other player also

- The flashlight works in both versions and casts shadows in both versions, while the PC modded one can get vastly superior lighting with certain mods like Giga lights, and you can see the effect of the light on surfaces from each player's flashlight no problem on all characters or all the environment, unfortunately right now when you look at the other player, there is no corona on the other player's helmet showing their flashlight is on right now, just something overlooked, I think that was always a feature in OG Halo 1 and Halo 2

- When you turn on the overshield in co-op, the visual effect only appears for the player who turned on the overshield right now, it is not visible to the other co-op player at all for some reason, for example if you are in third-person mode, it shows a clear overshield effect for your own character, but you can't see it for the other player if they have an active overshield

- The helmet reflection weapon/AR doesn't ever seem to be an actual ray-traced reflection, even while other parts of the reflection in the visor can be, like the other player or characters or environment lights sometimes show up, they are probably at significantly reduced detail also overall even if ray-traced, because the visor is so small relatively to other reflective surfaces, but the AR/weapon which is reflected on the visor seems like a mainly baked reflection, and there is probably a cubemap transparency thing also with the visor colour just like in the original to give it that classic look

Really cool feature for within KDE, but I think an update may have turned it back on for me, and it had my left analog stick controlling the mouse/camera look, which of course is not ideal during a game haha

The setting is at the top right "Allow using as pointer and keyboard"

Cheers, loving KDE! 🍻🍻🍻

A week or two ago I was exploring different options to get a full 4K60 RGB or YUV with HDR stream to my PC

The inspiration comes from Chiaki-ng which utilizes PlayStation's Remote Play feature, although this is capped at 1080p60HDR on a PS5, and comes with other limitations like limited DualSense features while playing through Remote Play

I ended up buying a pair of Elgato 4K X devices to test how the video stream could work with a HDMI input such as from a PS5, and you can likely easily use this with any other similar HDMI output devices

Elgato 4K X benefits:

USB-C connectivity, up to USB 3.2 I believe, and up to 4K120HDR or 8K60HDR support I think (per the device description, I have only used up to 4K60HDR so far)

HDMI input stream, rather than Remote Play:

higher quality streaming up to full 4K120HDR or 4K60HDR input (instead of capping at 1080p60HDR), and the benefit of full controller or DualSense features (haptics, directional rumble, controller speaker features, etc) while connected to the console, as well as access to all other features such as voice groups or settings menu access, some of which are restricted while using Remote Play

Overall benefit:

while there is a delay which is similar to Remote Play while using Elgato 4K X if you are playing looking at the stream through the Elgato 4K X, it is not very large, though it is definitely less responsive than a direct HDMI signal directly into a HDMI TV for example, but you get to for example record gameplay easily, stream gameplay live in Discord or other programs, or even play directly through this screen while using your PC on the same screen

Other notables:

It might be better to not use the Elgato 4K X passthrough HDMI, I *think* it might run more hot with it, and possibly this can contribute to more input delay to the USB-C stream to the PC, at least I felt that was happening

What I was doing was running HDMI from my PS5 Pro to a HDMI 2.1 Splitter (4K60HDR max output)

Also notable, the Elgato 4K X stream to the USB-C can *only support stereo* this is also listed on their product pages I believe, be aware of this so you do not expect 5.1 or 7.1 surround DTS or something through the USB-C stream to the PC, I believe it still passes through 5.1 or 7.1 audio through the HDMI passthrough though, but again, limited to stereo sound on the USB-C stream, which may lead to dropped sounds and audio missing if you have the console/HDMI input set to a higher channel audio input

Example, I was playing Saros and I noticed the audio log voices and even the cutscenes audio voices were not playing any sound at all, because the console was set to 7.1 channels, and was working fine as 7.1 on the splitter going towards my TV and sound system

Instructions

#remember to turn off hdcp on your device, as streaming capture may be incompatible with hdcp copyright protection, or other handshake features with hdmi input

#first connect your elgato 4k x device to your hdmi device, and plug the hdmi device to the *input* of the elgato device, then plug the usb-c to the usb-c of your target linux pc system for the stream, this usb-c will also power the elgato 4k x with no additional wires needed which is great

#ideally, this should be a usb 3.2 input into the pc, most likely directly connecting to the rear of your pc which should be directly into the motherboard, if your motherboard is new enough, check your mobo system specifications online for more information

#install flatpak of mpv https://flathub.org/en/apps/io.mpv.Mpv

#install a program which can view video input sources for linux

sudo dnf install v4l2-ctl

#list devices which can be utilized for streaming e.g. video0 or video1, usually video3 is for metadata only

v4l2-ctl --list-devices

#you can also use an unofficial tool for elgato 4k linux https://github.com/13bm/elgato4k-linux

#open the following commands where the linux version of elgato 4k x linux is located, needs sudo privileges to have usb access

#view firmware version information

sudo ./elgato4k-linux --firmware-version

#view status to read current settings including firmware, usb speed, hdmi color range, and hdr tone mapping setting

sudo ./elgato4k-linux --status

#if hooked correctly should list settings as 10 Gbps (SuperSpeed+) to allow for 4k60hdr rgb, this may also depend on your screen and TV to the maximum it might support from the usb-c input

#Reading current settings from 4K X (PID: 0x009b)...

#Firmware version: 25.08.15

#USB speed: 10Gbps (SuperSpeed+)

#HDMI color range: Auto

#HDR tone mapping: On

#if hooked incorrectly, it may show usb2.0 speeds of 480 mbps, and it will self cap the video to 720p30 no matter what video settings are used, can try re-plugging the hi-speed usb 3.2 cable into the elgato 4k x device and the pc again so it connects at the correct speed

#run the video stream into the flatpak version of mpv, this may only include video

#you may have to set /dev/video0 or /dev/video1, you can use the ( sudo ./elgato4k-linux --status ) from earlier to check this

#this will get the video stream working, but there may not be audio included

flatpak run io.mpv.Mpv av://v4l2:/dev/video0 --profile=low-latency --untimed --framedrop=no --cache=no --demuxer-lavf-o=video_size=3840x2160,framerate=60

#use pulse audio control to list audio sources, note the name of the input audio source to include in the following step

pactl list sources short

#notate the audio device input listed here to include in the next commands

#run the video stream into the flatpak version of mpv, with a combination of audio input from the input usb device

#remember to set the correct video & audio source

flatpak run io.mpv.Mpv av://v4l2:/dev/video0 --profile=low-latency --untimed --framedrop=no --cache=no --demuxer-lavf-o=video_size=3840x2160,framerate=60 & pw-loopback -i "alsa_input.usb-Elgato_Elgato_4K_X_A7SNB55031B03P-02.analog-stereo"

#or another example

flatpak run io.mpv.Mpv av://v4l2:/dev/video0 --profile=low-latency --untimed --framedrop=no --cache=no --demuxer-lavf-o=video_size=3840x2160,framerate=60 & pw-loopback -i "alsa_input.usb-Elgato_Elgato_4K_X_A7SNB601304SSG-02.analog-stereo"

#to get the sound to work, you may have to set sound settings input to elgato 4k x analog stereo in your sound devices options, this may disable other microphones connected to your pc as input

And after that, you should be done! Cheers 😎💎🍻

Working great with PS5 Pro and Chiaki-ng!

Using a 70 mbps cap with ethernet to switch to ethernet between the PS5 Pro and the desktop PC

For wifi connection to laptop I'm using a 35 mbps cap which works really well too

With iPad, iPhone, and Android I'm still using the official Remote Play app there
