gamescope VS corectrl

I think your information is quite outdated. The HWC overlay planes are heavily used, you can see this trivially just doing a 'dumpsys SurfaceFlinger' or grabbing a systrace/perfetto trace. When it falls back to GPU composition it's very obvious as there's a significant hit to latency and more GPU contention.

The overlay capabilities of the modern Snapdragons are also quite absurd. They support like upwards of a dozen overlays now and even have FP16 extended sRGB support. Some HWCs (like the one in the steam deck) even have per plane 3D LUTs for HDR tone mapping (ex https://github.com/ValveSoftware/gamescope/blob/master/src/d... )

The composition is bandwidth heavy of course, but for static scenes there's a cache after the HWC in the form of panel self refresh.

One of the unfortunate things about Wayland is every compositor will have its own quality of implementation affecting things like latency.

With XOrg, especially in the pre-compositing days, you could choose whatever WM you want and it wouldn't have any impact on the rendering performance of X clients. Once the Composite extension was added and everyone started running composited X desktops, that started to change, and the increased latency already started appearing - in an arguably worse architecture than Wayland because there were often three processes involved with lots of IPC per draw: X-Client->X-Server->X-Compositor->X-Server->CRTC. At least in Wayland it's more like Wayland-Client->Wayland-Compositor->CRTC.

If you're unhappy with the rendering latency of your Wayland sessions, it may be worth trying alternative compositors... they likely vary significantly. The Valve/Steam folks have made a minimal one specifically optimized for games/low-latency [0]. I doubt the SteamDeck would be seeing as much success as it is if Wayland were so problematic in this department.

Use gamescope.

While streaming from the Deck to another device (phone with Steam Link app or another PC running steam), taking a screenshot on the Deck (hold the steam or ... button, and press R1) crashes the session (https://github.com/ValveSoftware/gamescope/issues/961). This one also impacts Decky Recorder. If you're recording the screen or have replay mode on and take a screenshot, you'll have a crash.

Mangohud (GOverlay), libstrangle, gamescope. Pick your poison.

Hey folks. I've got a 11900H motherboard and use the iGPU and stock Intel graphics drivers that I keep current. Even at baseline (so without overclocking of any kind, with good Corsair memory sticks configured without XMP and regardless of voltage), I would be able to use Windows 11 and the CMD or Terminal programs without issue but after some time they would be corrupt and unreadable. The fix was in Terminal, go into Settings, then Render, and turn on Software Rendering. I hope this helps someone else. FYI the corruption was very much like other Intel UHD graphics samples reported in this link: https://github.com/ValveSoftware/gamescope/issues/356

Have you tried CoreCtrl [0]?

I have a 7900XTX and performance under Linux has been at least on par with Windows, sometimes better (though not by much).

> May i ask what driver features are you missing?

I'm not GP but I'd love to see frame gen and stuff like anti-lag and upscaling integrated into amdgpu with some sort of official way of setting it (though looking at Adrenaline it might actually be best if it's left up to the community to create the GUIs).

Basically the 7800 xt has this bug where I need to lower the core clock of -80mhz to avoid it crashing with 2 different hdmi/vga monitors or something. On windows no problems, but what about arch linux? How do I lower it? Looks like corectrl doesn´t support 7000 series gpus (from what I understood), please help yall!

sudo grub-mkconfig -o /boot/grub/grub.cfg Reboot your system. You should have more controls when you select Advanced as Performance mode. https://gitlab.com/corectrl/corectrl/-/wikis/Setup

> The AMD experience on Linux is vastly better than the Nvidia one.

I just wish we had an equivalent of AMD Software on Linux, so I could mess around with the settings more.

For example, I like to limit the GPU to 50-75% of it's total power for ambient heat/cooling reasons, or UPS/PSU/electricity bill reasons when specific games make it hard to cap framerates.

With AMD Software on Windows, it's no big deal. On Linux, the best I found was CoreCtrl: https://gitlab.com/corectrl/corectrl

Sadly, it doesn't seem to work all that well for my use case, which I mentioned in my blog post when using Linux instead of Windows as my daily driver at home too: https://blog.kronis.dev/articles/a-week-of-linux-instead-of-...

> You see, by default the card controls its own GPU and memory clock values, which means that when idle the GPU draws around 40 W of power. However, if I want to set a limit for how much W in total it can use, it also makes me set the GPU and memory clock values, which will them be fixed: so at idle the GPU will use about 60 W of power.

If you set it to POWER_SAVING instead of 3D_FULL_SCREEN, it uses the highest boost clock a lot less. Or if you use something like corectrl's application profiles (maybe the Windows vendor driver control panel has them?), you can selectively disable boost clock states in specific games.

I'm bias toward Asus motherboards. I have an "Asus TUF GAMING B550-PLUS WIFI II" and a "Asus ROG Crosshair VIII Hero (WI-FI) ATX". Both boards have a fan control feature in the BIOS/EFI. On the Windows side both boards come with Ai Suite 3 software. On the Linux side you might want to take a look at Corectrl ==> https://gitlab.com/corectrl/corectrl

I think CoreCtrl might offer some of what you're looking for.
