This is from a post made in forum discussion with a user Ragnar Lothbrok.
So I decided to put this on Tips also since it seems it's a detailed information that might help others too.
I want to specify from the start that these tips work on Linux & MAC OS (that are before M2 architecture, after M2 I cannot guarantee, see at the bottom of the post for the explanation)
What I done to play the game only with Vega 11 (integrated graphics card
from Ryzen 5 3400g) without a dedicated video card are these :
Now ingame graphics settings :
Resolution : Window, i play this way for many years already
(including when I was still on Windows 7/8), you can make it possible to
retain the Ubuntu Launcher Applications Bar (some know it as Unity)
while the remaining space it's occupied by the game. And from this point
you can see the ingame texts more better, your FPS improve, and you can
browse Firefox or do work stuff while being AFK ingame. Just use the
Windows button between CTRL + ALT (some have as FN)
Frame Rate : Default (this is in gray, at least I can't change it)
Frame Limiter : 30 ( it's enough for every kind of decent action, and
it can help in WvW to don't get "Lag/Skipping frames" vibe, even for
powerful graphics card, and the extra resources are saved by giving a
constant FPS)
Interface Size : Large (or normal, as you wish, doesn't impact)
DPI Scaling (you can have it unticked/unchecked when on WvW)
Animation : Low
Antialiasing : None
Environment : Low
LOD Distance : Low
Reflections : None
Textures : Low
Render Sampling : Subsample
Shadows : None
Shaders : Low
Postprocessing : None
Character Model Limit : Lowest
Character Model Quality : Lowest
Unticked (they don't have a check mark in it)
Checked (with a check mark in it)
And this is it.. I should note that the developers made a few modifications before Summer 2023 and they added even more lower settings as options and if you choose the Settings Preset : Best performance, it isn't updated yet to these new lower settings.
From here onward any updates from the Anet game developers make, can affect any of us, in good or bad way, and until it's fixed, we can only wait and hope they fix it, if not.. there is always possibility to create a forum post or report bugs.
And it also depends if you have AMD or NVIDIA graphics card (or the integrated ones from AMD or Intel)
Some players confirmed that the changes made in the game engine were good, but it still heavily relies on the Processors, and a good dedicated graphics card it only helps you if you play in dungeons with high number of animation processes (like Harvest Temple) or if you play in World vs World with zerg fights which count on each side more than 20 (my Vega 11 can handle if my team and enemy is about 15 each, higher than that FPS drop and I take guesses where zergs will move, and do a AOE skill in a area and see how many get inside it ^^ )
What I can confirm is that a friend of mine sometimes plays GW2 under Debian with Lutris (latest Wine) and is still impressed by the fact that there is only a average of 5 FPS difference between Windows and Linux, while -5fps being less in Linux, it's somehow more smooth to play than on Windows, and had less crashes than on Windows, something about deleting some temporary files from tmp document or something similar, that re-appear when you start the game anyway, and btw.. this should be No.1 thing to do if you have any kind of crashes on Linux)
And ArenaNet (or NCSoft) dropped support to continue on Mac OS on the new ARM Chipsets like the M2 (it's same used on SmartPhones and small electronics with lower power consumption) cause they can't remake the game and adapt to a unique graphics card (something like that, but the more detailed information can be found on web)
At least these info should help.
Good luck and have fun :)
