Well depends alot on what ur Gfx card is, which monitor etc
But for short as possible to make game more smooth with stable FPS
First when u open ur Steam then go to Libary and right click on cs:go > Properties > Set Launch Options
I have this in "-console -freq xx(replace xx with ur screen hz f.eks. 60 75 or 144) -full -novid -high -noborders -noforcemspd -noforcemaccel -tickrate 128 -nod3d9ex -nojoy +cl_forcepreload 1 +mat_disable_fancy_blending 1"
Then go to ur steam folder like C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\cfg and make a new "autoexec.cfg" file and
paste the autoexec text or whole cfg i have attached into that folder and u can add "other stuff like "crosshair" settings binds etc. but remember to make cfg when u done as "read-only" so that cfg cant change while game and add "+exec autoexec.cfg +exec autoexec -exec autoexec.cfg" to launch options and if u can find ur normal config.cfg file at the bottom "exec autoexec"
Then i made a "1440x1080" custom resolution like u can see here here all pictures incl. my radeon settings + radeon pro settings
here link to imgur witch all pictures am - Album on Imgur
In cs go i use 4:3 1440x1080 as u can see on picture
Most important is to use "Radeon Pro" to only let direct x 9 allow to run in 4:3 is for me that played since Half-life a big difference ...cant explain how much but does alot for my game ..
Hope it helps ..if needed more detail or question then ask again
why should i use Radeon pro? and i cant understand because u not using english in the amd radeon...
i need less input lag and most fps, cuz im playing competitive ..
Which language do u have in ur Radeon?? even with other language the place where the boxes are and numbers are the same....
Radeon Pro has more acces and possible to change alot more settings then the amd driver has by itself. u can for e.g set the Direct X u want to use for the Game
In CS:GO when u set radeon pro to only use "dx9" and disable all others and OpenGL then u vil get higher FPS and steady FPS to. Because CS go is made from cs 1.6 steering and source graphics. The 1.6 steering is more smooth with dx9 since that was used back then and dx9 uses less power from ur GFX card.
Also in Radeon Pro under Anti-Alising u can set it to CFAA(edge-detect and with ingame Anti-Alising to 8x u can see more through Mesh
u can set Trilinear Optimizing on and ingame set it to Trilinear to improve fps. Also u can set Anti-Alising compatíbillity to "Unreal Tournament 3" so it improves fps again.
Tripple Buffering can be tricked so u can set it to ur monitor Hz
U also can Disable windows "Aero" , set prio to High and set how many CPU core to use
and last u can set the cs:go client launcher which is "Steam" so the game get easy acces
so Radeon Pro to set dx9 only to run . anti alising and make custom rezolution for 4:3 with Amd CHill active then ur have no lag at all...
