Low FPS Fglrx Linux

[Moranthil]

Hi.

I have a low FPS in all games - for example Dota 2, L4D 2 on Linux. My distro is Manjaro. I have installed fglrx drivers and catalyst. I tried Debian - this same. On Windows all is fine, full details, native resolution. How to fix it, because i can't play anything?

Specification:
C2D E8400, AMD HD7770.

[Rosen]

i ask the same..

FX 8320 16GB DDR3

Radeon HD 5770

Large input lag, low fps..

[TEO RADALJ]

i dont agree with pike, if game is supported and have linux version then usually works even more smooth on linux,and even more FPS then on windows.., ..well Steam OS is Linux!

to moranthill and roko, just paste what u get when u type in terminal :uname -a,and then what u get when u type in terminal : fglrxinfo, when u ask for help..about fglrx driver

following with output of aticonfig --lsa ( ati gpu card u have)

to moranthill: catalyst is fglrx ,not catalyst and fglrx..its same driver..

also to both: even opensource driver(Galium) run fine (mostly +/- 5FPS) on Steam! i play Talos Principle on 6850 with 30fps..with it..and with fglrx(closed source amd driver)..

i bet both of u dont have fglrx properlly installed.

for bottom line ,to pike ,and simular thinking guys:

when game have native linux version ,it run better and more smooth with bigger FPS then on windows,or at least same..that is fact so ofen ,almost as rule...but there are still more games in general and on Steam for windows platform,and that is fact,too..

( you like windows,ok, no problem,enjoy!)

(am not OS fanboy,either CPU fanboy or either GPU fanboy)

(simply i have my choices what suits me better)

@vadim

linux ports or linux native?

sure before nvidia had better drivers for linux..but now..difference is not so big as before...

linux ports from windows you said have less FPS ,well, like ports from console to pc ,not have simular problem?

if is port,then is port,not native version!

re this @ROKO configuration for gaming on linux and gaming..
FX 8320 16GB DDR3
Radeon HD 5770
Large input lag, low fps..

smaller part of input lag can be from controller(gamepad,and bus it use), other bigger part is graphic card that ask for upgrade,or to run in lower,and lower resoulution,

RAM 16GB is more then enough,

and 8320 is more then enough,in futere can be clocked..as per need..4.7 why not!

but sometimes in some particular not optimised games for more then 4 cores it is better to run 4 cores,i mean to switch off manually 4 cores and to run it on 4 cores fixed on 4.0 or even 4.5 or 4.7? try

(even better cooling you will not need till some range,4.0 fixed on 4 cores is nobrainer..)

or to clock it at all cores at least at 4.0 to run it on clock of 8350 and use it as 8 cores..even more, (big NO,dont do it on stock cooler!)

sure is hard overkill of ram and cpu for that card...simply u have potentionally gaming rig but not with that gpu!

and even i use amd cards with linux i recommend nvidia ,too

but sure if you upgrade gpu look for more vram ,2GB and wider bus,example 256,and yes look as high as u can aford at moment,forget and dont plan crossfire in any combination..even i use it,sometimes! (not worth,belive me!,same apply for SLI)

and even i use amd gpu, i will recommend to u to go nvidia..simply they have better linux drivers,less hasle..better ,but not so much better as before...but YES better linux drivers!

and lag can be also from your hard disk if ur still on sata1-2? upgrade to sata3 or even better to any SSD..any regardless how small is ,its better then hdd..

and maybe this sites can tell u something:if lag is in multiplayer && online games

http://www.speedtest.net/

http://www.pingtest.net/ if your grade is C,or you found that you have packet lost...

so till gpu upgrade,or any other upgrade(no need for cpu ,or ram upgrade, to be honest it is,and probablly will be overkill even when u upgrade gpu!)

just run games at lower resolution, and reinstall drivers, i will go on one version back from newest..and sw off 4 cores in bios and fix clock to 4.0 if i were on ur place! all that without any thinking..and yes nobrainer is to use driver which no have fglx-core package..(just check if u have it installed..if u dont then u dont have last amd driver,sure!,but maybe u need really to triple check if ur drivers are good instaled, so first purge fglrx!!!then reinstall it,or install newer..)

[TEO RADALJ]

@vadim i see u understean,

if something is built to run perfect on particular os,run it on that for perfection..

but vice versa, someone can buy only what run good or strictly perfect on his chosed OS.

do mac users buy windows licence just to run windows only games,mostly not,they buy games for mac..

if they not make it for OS what now i prefer for casual gaming, i will continue to vote with my wallet! so,simple!

well do u agree that will be funny to see,just for 1april 2015 that is entering windows licence online to valve account obligatory..to play windows only games!

[TEO RADALJ]

@Moranthill -- run bleachbit as root..

-- check number of bacground process

-- install low latency kernel (its more responsive ,good for games)

-- install Talos Principle DEMO for linux,and if you cant run it smooth ,well then sure your linux configuration is bad!

[TEO RADALJ]

@vadim yes i agree,with you, about optimisation for directX,and much more time and money involved in it... But more and more AAA are optimised for GL..and wide platform support is reallity,reason is simple-- money. mac,linux,android..all are same -- unixoids!...right!? and windows run nice also GL optimised games..same as mac,linux,androids..so why to develop just for directX? and cut money income,and growing market..no,no..

Are you running a clunky DE with a compositor (unity, compiz, etc)? If so, turn off redirecting of fullscreen windows. Best to disable the compositor entirely/uninstall it.

I remember when I used Ubuntu, unity was using up so much gpu resources. I got a 150+ fps boost and eliminated input lag by turning that crap off. I think I ended up switching to Ubuntu Gnome remix. XFCE might be good as well as other "light" DE.

Also like others have mentioned I recommend using the low-latency kernel.

FWIW i'm on:

Linux Mint 17 (Ubuntu/Debian based)
i5 3570
AMD 7850 w/ latest stable fglrx
res: 1680x1050 native

fps flucuates 150 to 300 approx in CSGO

[Bushido Brown]

Also I just noticed you are playing some source games. Fiddle with the multicore rendering and the mat_queue_mode var. Vsync enabled has also been known to introduce lagginess.

Hope I helped some. I remember myself spending DAYS googling around for fixes.

So the GPU was changed 6 months ago. from 1 year i use SSD Radeon R7 120GB and Western Digital Red 1TB 64MB cache. I runing in overclock since i build this machine, i have NH-D14 cooling system. Nvidia and AMD linux drivers are very similar i think...
I was nvidia fan long time ago, but i am out of nervs because of nvidia hardware failures.. they just burning... i have one box with broken nvidia cards..And i am affraid to buy again nvidia..

my connection is fiber and speed is same in whole Europe.

Sorry, but you're wrong. AMD linux drivers are low quality and low performance. More than that, they often cause game crashes and graphic artifacts. Some linux games, like Alien Isolation, doesn't support AMD graphics at all.
You can find more detailed info and benchmarks on, say, www.phoronix.com.
Look at this chart: http://www.phoronix.com/scan.php?page=article&item=bioshock-nvamd-preview&num=3

[Rosen]

i am sure that the drivers are very similar, just developers making thinks work better on nvidia gpu's but at all Linux OpenGL stack is broken... So i can buy Nvidia GPU in close future but for now i asking for improvement tips about my GPU.

easy: newer kernel,now 4.2 is stabile,newer version driver fglrx-updates came along with it,or just instal newer version of fglrx or fglrx-updates..whatever..as now open GL is 4.5
further is to consider to use low lantency kernel ..
more further is to use other lower consuption desktop,but most of rig for gaming do not need this..as most have enough ram,etc..but if you are on less then 4GB..then that can go in..otherwise is not worth generally..or is worth to have other scenario..one OS (perhaps Steam OS) when you need gaming ..on other partition other OS for other and general purpose..to avoid using of Steam launcher on top of general purpose linux OS..

[Rosen]

so wake up.. I post my kernel version and catalyst. They are 4.3 and 15.9 using gentoo linux with kernel build by me for high desktop response.. I am not sure if i can make more about kernel configuration..
