Xonotic or Quake?

I know 4 major servers: Feris and 3 Jeff’s. Feris is most populated one during European night. And there are pickup servers that usually play 4v4. Also smaller servers exist that occasionally get players like xonotic-relax.ru.

Play Xonotic in Linux. Or Quake.

Doesn’t DirectX require a lot of stuff from winapi?

Only two things. Rust is 12 gigs on disk(which translates into 12 gigs of ram if you use tmpfs) and IDK how much in ram. Chromium is about same. Keep rest of ram for linker.

Average web developer principle

How? After booting(and starting DE) I’m using about 700 megs.

Compile chromium, firefox or rust

QT + KFramework. SDL2 for games.

Cute

I mean real-time scheduler, not real-time kernel. Found an article that says kwin_wayland uses SCHED_FIFO.

man 7 sched says:

SCHED_FIFO can be used only with static priorities higher than 0, which means that when a SCHED_FIFO thread becomes runnable, it will always immediately preempt any currently running SCHED_OTHER, SCHED_BATCH, or SCHED_IDLE thread.

but decreases performance slightly rather than increase responsiveness.

Responsiveness is not performance. There are 3 main performance metrics: throughput, latency and jitter. Responsiveness is mostly latency, but sometimes jitter. You can for example run game in 30fps with 0.01s lag or in 60 fps with 1s lag. In second case FPS is higher, but, player will feel game unresponsive because of time it takes between pressing button and game showing the result.

No. march is avaliable instructions and mtune is timings. mcpu does, but it is not used on x86 for some reason

3. Play games with SDL_VIDEODRIVER=kmsdrm

Let’s begin that Nvidia’s proprietary drivers is main issue

Do it.

Gentoo with -march=native -mtune=native on x86(-64) or -mcpu=native everywhere else

I’d wager that it’s your scheduler.

How did you know??

Linux used the CFS scheduler which is outdated and not really optimal for desktop usage.

And Linux kernel is full of outdated math. Like outdated addtion, outdated subtraction. /s

If you want “like on windows”, then you need dynamic priority, not another scheduling algorithm. Basically you want your compositor to set lower priority value(which means higher priority) to process whoose window now is focused.

Depending on what you perceive as snappiness, it is because of misconfiguration.

If you perceive response time of desktop enviroment snappiness, you need to configure desktop server(xorg-server, kwin_wayland, xwayland) and compositor(or disable it) to run in real-time mode. Maybe there is also “prefer smoothness” option in you desktop enviroment settings like on KDE.

If you play games, then migrate to X11. Games don’t know how to enable tearing on wayland. And in general X11 seems to work better with games.

I hope by partition UUID you mean root=PARTUUID=, not root=UUID= because kernel can understand only PARTUUID.

Kernel says it can’t mount root device. Maybe it is not specified or kernel just can’t find it. You need to edit root= parameter for kernel. For:

1. GRUB: press ‘e’ to edit menu entry and then press ‘F10’ to boot
2. LILO: just append desired root=
3. EFIStub: change it in config and recompile it

If you use GRUB you can use its console and search for disk and partition where root fs is located.
