[SOLVED]Video games not running smooth but fps is high

delyan05 · 2020-12-15 15:40:27

Hello, I am using dwm and i installed nvidia drivers from arch repository. I have geforce gtx 1050ti. On glxgears i have 50000fps. On euro truck simulator 100fps but not running smooth. When i turn on vsync. It's the same. Please help me!

That's often an issue of the CPU scheduler, try a more desktop/responsiveness focused scheduler, like the tuned one from linux-zen or linux-ck or so. To install either of these in combination with nvidia you need the headers of the relevant kernel and nvidia-dkms (in case of the in repo linux-zen you need to install linux-zen-headers as well as nvidia-dkms

Why would the scheduler matter if he's already running at 100fps?
@delyan05, please elaborate on "not smooth" (looks more like 10fps, tearing, …) and provide more details on the environment, in particular whether you're using a compositor along dwm and if this is a hybrid graphics system (additional intel chip)

I have just installed linux-zen and linux-zen-headers and i tried to play. This fixed my problems. Thank you very much!

delyan05 · 2020-12-15 16:23:28

I will check again and give you more information

delyan05 · 2020-12-15 16:24:24

I have ryzen 3 3100 and palit 1050ti. The ram is 16GB-2x8GB 3200mhz.

delyan05 · 2020-12-15 16:26:12

Ooh i checked again but the problem isn't fixed.

delyan05 · 2020-12-15 16:28:38

I am not using compositor. Not smooth means that i have small lag spikes but only on the monitor.

delyan05 · 2020-12-15 16:33:24

My chipset is b450.

seth · 2020-12-15 16:34:38

Please don't bump, just edit and mend your posts if nobody has replied so far.
Also think and then post, not the other way round ;-)

Most important output you didn't post: "lspci".

Can you quantify "small lag spikes"?
Does "euro truck simulator" allow you to chart the fps?

delyan05 · 2020-12-15 16:38:10

In euro truck simulator fps is 100 fps.
Small like spikes means that the video on my display is not running smooth.

Afaik this has something to do with frametimes and CFS being comparatively bad here, see e.g. https://flightlessmango.com/benchmarks/zhs_-FOHSZU or https://flightlessmango.com/benchmarks/zhs_-FOHSZU

But aside from those I can only speak from personal experience in this case and e.g. Street Fighter V has an annoying stutter on the stock kernel that's very noticeable but isn't being reflected in the normal FPS listing. Using MuQSS or PDS helps here YMMV.

Edit: Please wrap outputs in

So "not smooth" means "small lag spikes" and "small lag spikes" means "not smooth"…

If the simulator was running at a constant fps, you'd not notice any lag (spikes)

Do you notice similar "lag spikes" in glxgears?

@V1del is that benchmark specified (ie. do we know what other processes run in parallel - like eg. tracker ;-)?

delyan05 · 2020-12-15 16:59:20

Yes i also have lag spikes in glx gears if sync to vblank is on. If i turn it off, i don't have lag spikes, but if i play euro truck simulator 2 with sync to vblank turned off the fps 100 but i see it too laggy.

So it's a vsync issue? Do you have the problem in ETS when turning vsync *off*?

delyan05 · 2020-12-15 17:03:18

Yes i have the same issues.

V1del · 2020-12-15 17:08:30

Not sure and I just picked one to illustrate what I'm talking about. And if we couldn't have a tracker randomly deciding that now is a good time to start indexing, what would be the point of a scheduler anyway?

Not but seriously, I dislike making suggestion like these based on "feely" in this context as much as the next guy, but I've noticed the issue often enough and don't know enough on the subject to give actual hard info on why it does make such a difference other than that it's pretty noticeable when you actually see it.

FWIW afaik zen also uses CFS by default but lowers the tunables so it reacts more aggressively: https://liquorix.net/

Regarding the apparently still existing problem, another thing you might want to give a shot is enabling the performance CPU governor: https://wiki.archlinux.org/index.php/CP … _governors

Please try to enable triple buffering, /etc/X11/xorg.conf.d/20-nvidia.conf

Section "Device"
    Identifier "Default nvidia Device"  # random string, but mandatory
    Driver	"nvidia"  # mandatory
    Option	"NoLogo"				"True"  # no advert
    Option	"CoolBits"				"24"  # can offer more options in nvidia-settings
    Option	"TripleBuffer"			"True" # <= this is the important one!
EndSection

delyan05 · 2020-12-16 07:11:31

I don't have file 20-nvidia.conf.

seth · 2020-12-16 07:58:19

And what are you going to do about that…?

The Zen kernel has BFQ as the default scheduler. :-)

V1del · 2020-12-16 09:11:56

IO yes, but I'm talking about the CPU schedulers here.

tydynrain · 2020-12-16 09:45:18

Doh! That's my silliness. I don't know how exactly I missed the CFS instead of CFQ part. My apologies. :-P
