Star Citizen

[3.12.X] Optimization & User.cfg

o7 Citizens, I wanted to share my user.cfg and optimizations that I use to play the game with minimal crashing and great framerate with a medium-high end rig.

I see a lot of people in Global Chat complaining about client crashes (not 30K). Star Citizen is an Alpha and it is normal to crash. BUT, I believe that there are some things you can do to make the game run smoother and more consistent on your end.

By no means is this a "fix" or better than default settings, but I do get overall less crashes, more consistently. This may not work for everyone so no guarantees:

First lets show you 'My Setup'

  • CPU: i7-9700K @ 4.8GHz
  • GPU: ASUS RTX 2060 Super
  • RAM: 32GB @ 3200 MHz
  • Crucial MX500 SSD (No paging file enabled)
  1. The first thing to do is to Navigate to 'C:***StarCitizenLIVE' and add a new file named USER.cfg

Add the text:


sys_maxFPS = 0 // framerate uncapped

sys_maxIdleFPS = 0 // uncaps idle fps

r_VSync = 0 // forces vsync off

r_MotionBlur = 0 // turns off camera blur

r_ssdo = 1 // turns screen shadow gloss down

r_DisplayInfo = 3 // shows some connection and pc information


q_ShaderDecal = 3 // default value is 3

q_ShaderFX = 1 // default value is 3

q_ShaderGeneral = 3 // default value is 3

q_ShaderGlass = 2 // default value is 3

q_ShaderHDR = 0 // default value is 3

q_ShaderParticle = 2 // default value is 3

q_ShaderPostProcess = 1 // default value is 3

q_ShaderShadow = 3 // default value is 3

q_ShaderSky = 2 // default value is 3

q_ShaderWater = 1 // default value is 1

ui_disableScreenFade = 1 // disables fade between screens

  1. Open the ''C:***StarCitizenLIVEUSER' folder and delete 'shaders'

  1. Navigate to 'C:***StarCitizenLIVEBin64' and locate 'StarCitizen.exe' –> Right-click properties

Can be enabled for bordless or fullscreen.

  1. These are my video settings:

Turn off Film grain, Chromatic Aberration, Motion Blur and VSync – Can be Fullscreen or Bordless (I use bordless because I have two monitors)

  1. Windows settings:

enables GPU profiling – can be very beneficial lowering latency

Gaming Mode can be beneficial to some games but it disables a lot services Window's "thinks" should not be running.

  1. ***OPTIONAL & NOT RECOMMENDED for Non-Advanced Users***

ALWAYS BACKUP REGISTRY if you don't know what you're doing!

Windows 10 by default uses Nagle's Algorithm to bundle data packets. By modifying the registry you can have an unbuffered flow of packets if your internet connect is consistent (i.e. wired and not wireless)

Hold Windows key + R, and type regedit

Navigate to ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParametersInterfaces

Match the folder with the IP address that is found when you run ipconfig in CMD and add the two 32-bit DWORD's



Edit value to 1 (see image)

You need to find your local IP address first before adding the DWORD keys.

That's it. I hope it helps a few people out. I know how frustrating crashes can be. If this doesn't change or makes things worse for you, just delete your ''C:***StarCitizenLIVEUSER" folder as well as the USER.cfg and everything will be reverted back to default (also re-enable fullscreen optimizations in properties).

This game is amazing and hope it gets more optimizations. Best of Luck! o7
