A "Very Low" setting for PC users

17 posts
edited June 2016
As a person with a terrible computer (Intel Core 2 Quad 9300 @ 2.5GHz, 4GB RAM, 1GB Nvidia GTX 650, Windows 10) I decided to spend some time developing "Very Low" setting so that others might enjoy Mirror's Edge Catalyst even if their system specifications don't match minimum requirements.

UPDATE: DICE has kindly included a more advanced way of controlling rendering quality. I am updating this post to advise users they can now use in-game settings to improve performance.
  • If you get "Out of Memory" errors, try increasing your page file to a fixed size of 8 to 12 GB
  • In-game you can press GRAVE/TILDE (`/~) to open up the developer console. I suggest "GameTime.MaxVariableFps 60" at the very least. The console shows available commands as you type and supports TAB completion.
  • You can create a "User.cfg" in "C:\Program Files (x86)\Origin Games\Mirror's Edge Catalyst\" for any settings you find useful and want to keep around permanently.
  • I find a resolution of 1280x720 with a render scale of 0.75 and post-processing set to "Low" or "Medium" to be a decent trade-off.
Example "PROF_SAVE_profile" settings:
GstRender.AmbientOcclusion 0
GstRender.AnisotropicFilter 1
GstRender.AntiAliasingDeferred 1
GstRender.AntiAliasingPost 1
GstRender.Brightness 0.500000
GstRender.ClampGpuMemory 1
GstRender.Contrast 0.500000
GstRender.EffectsQuality 0
GstRender.Enlighten 0
GstRender.HaveNewQualityLevel 1
GstRender.LightingQuality 0
GstRender.MeshQuality 0
GstRender.MotionBlur 0
GstRender.OverallGraphicsQuality 6
GstRender.PostProcessQuality 1
GstRender.ReflectionQuality 0
GstRender.ResolutionHeight 720
GstRender.ResolutionScale 0.75
GstRender.ResolutionWidth 1280
GstRender.ShaderQuality 0
GstRender.ShadowQuality 0
GstRender.TerrainQuality 0
GstRender.TextureFiltering 0
GstRender.TextureQuality 0
GstRender.ThreadMaxProcessorCount 4
GstRender.TransparentShadows 0
GstRender.UndergrowthQuality 0
Example "User.cfg" settings:
GameTime.MaxVariableFps 60
PerfOverlay.DrawFps 1
PerfOverlay.DrawFpsMethod 1
PerfOverlay.DrawGraph 0
PerfOverlay.DrawGraphMethod 1
PerfOverlay.Enable 1
PerfOverlay.FpsDisplayFormat 0
PerfOverlay.FpsDisplayOffsetX 10
PerfOverlay.FpsDisplayOffsetY 10
PerfOverlay.FpsDisplayScale 2

    Cool! I have Intel Core 2 Quad 6600 @ 2.4GHz, 4GB RAM, 1GB Nvidia GTX 650ti. It is almost but not quite playable at low - too unpredictable. Was hoping that day 1 patch plus new nvidia driver would help but this sounds promising.
  • I checked and the User.cfg file is not in my Mirror's Edge Catalyst folder nor any of the other folders under Origin Games.

    I also looked in the My Documents\Mirror's Edge Catalyst\ folder and only found my profile files there.

  • You need to create it, which is why I suggest right clicking the "Raw" button and selecting save as; you can then drag the file to the install folder.
