I’ve noticed from time to time, that people with high-end/mid-range systems are have performance issues.
So here is a list of all possible launch options for rust. there is a small list of the fps difference between
options when I run them, hopefully it will help people with high-end/mid-range systems be able to tweak their
launch options to get better FPS.
Resolution 5760 x 1080 (3 monitors), all taken from the same spot with grass off.
AvarageFPS : DAY / NIGHT
FPS = 55.6 / N/A# : -force-d3d11-no-singlethreaded
FPS = 55.1 / 89.2 : -force-feature-level-11-0
FPS = N/A# / 82.6 : -force-feature-level-10-0
FPS = N/A# / 65.1 : -force-feature-level-9-3
FPS = N/A# / 47.3 : -force-opengl
It’s worth making note, that as it got darker ingame FPS generally increases, yet even with this help opengl performance
is as poor as expected. thus if your running similar specs and get poor fps, its likely your game has decided
to run in opengl mode try forcing it to feature-level-11-0.
All possible launch options:
-popupwindow [same as turning the windowmode tick box off]
Recommended Test Server(s):
184.108.40.206:28185 : USA : Always Day Time : (run by xEnt22)
Finally you can edit the config.cfg and turn grass off for maximum potential performance.
change all grass options to false
list of extra options for the config.cfg to help people with lag.
and if you wish to see your FPS in console add
How To Disable/Enable All Shadows:
To disable all shadows ingame and potentially increase FPS further or simply have the chance to decrease load on your GPU thus reduce its temperature
replace unity default resources & unity_builtin_extra in <game-path>\rust\rust_Data\Resources with the disabled_shadows files provided above.
please note this is not the best option and im sure devs will add a shadows.off option to the config.cfg eventually but until then this should help.
