[SOLVED] Why is my FPS much lower in Arch than in Manjaro?

iSohaib · 2018-05-09 23:50:43

Hi all,

I have a desktop pc

CPU: Intel® Core™ i5-2500
GPU: Intel® HD Graphics 2000

The tested game is UrbanTerror

After a fresh install I get high FPS in both Manjaro and Ubuntu,
I don't need any additional drivers or configuration.

But in Arch i get very low FPS, I think Arch is missing some configuration or libraries,
What can cause the problem?

How have you setup Arch?

Moving to NC....

pacstrap /mnt
arch-chroot /mnt
pacman -S intel-ucode
pacman -S xorg-server (choosed libglvnd)
pacman -S gnome (choosed libx264)
systemctl enable NetworkManager
systemctl enable gdm.service

I meant the graphics stack...

I havent changed anything, everything as default

You haven't installed a driver?

You are probably going to be much happier sticking to Manjaro...

I think my graphic card dont need any additional driver

I found this guide https://wiki.archlinux.org/index.php/in … stallation but after trying to install mesa It looks already installed by default

Nothing to do

I will be happier if I successfully configured my Arch :-)

Merely installing the microcode package doesn't do anything, so start by fixing that. In general, the steps you posted to not constitute a sane and complete installation - where did you get that?
Then you should check which display server you're actually using and whether it was the same on the other system - notably since ubuntu probably didn't ship wayland. This also holds for GDM which will by default run on wayland and open a second display for xorg sessions.
As for xorg as display server, there indeed *is* xf86-video-intel; whether that was used on the other systems and whether it's faster than the modesetting driver, idk.
Then there's your "testcase" - "UrbanTerror" is no arch package, so we do not know *anything* about it, esp. whether the particular build relies on glx and thus will in doubt run on xwayland.
Next thing is vsync (if you're "stuck" w/ eg. 60fps on an 60pfs output, the cause is obvious)
Otherwise it's relevant to check what's actually the limiting factor - IGP or CPU.

The actual status quo of your provided information is "I somehow installed archlinux and get less FPS than expected in some unspecific process" - you might understand that this is completely insufficient to make any informed statement..

Thank you for your answer
This kind of answer i'm looking for
The problem is solved after loading Gnome on Xorg

I collected my installation steps from Arch wiki and I made simplest installation possible
I don't think that i need anything more
these is my steps

##configuring network
##partitioning and mounting
pacstrap /mnt
genfstab -U /mnt >> /mnt/etc/fstab
arch-chroot /mnt
##configuring localtime and language
##configuring hostname, users and passwords
pacman -S intel-ucode
pacman -S xorg-server
pacman -S gnome
systemctl enable NetworkManager
systemctl enable gdm.service
##installing bootloader and adding initrd /intel-ucode.img to bootloader entries

Everything as default
The FPS was before about 58fps - 63fps
But after loading Gnome session on Xorg the FPS became up to 120fps, faster than any other linux distro =-D

Thanks for all

Arch is the best
