1. Disable Post-Processing First

Why it matters: Post-processing (motion blur, depth of field) eats GPU power even when the game isn’t running. Leaving it on is like revving your car engine while parked!
How to fix:

• Go to Window > Cinematics > Post Process Volumes.

• Disable ALL post-process volumes in your scene before animating.

• Re-enable them only for final renders.
  Pro Tip: Create a “Draft Mode” preset with post-processing turned off for quick toggling.

Console Command:

r.PostProcessing.Disable 1

Disable ALL post-process volumes before animating. Re-enable for final renders:

r.PostProcessing.Disable 0

2. Scalability Settings to Low

Why it matters: Lowering shadow, texture, and lighting quality reduces real-time rendering strain.
How to fix:

• Press ` (tilde) to open the console.

• Type sg.ShadowQuality 0, sg.TextureQuality 0, sg.EffectsQuality 0.

• Alternatively, go to Settings > Engine Scalability Settings and set everything to Low.
  Don’t worry: This only affects the editor — your final render quality stays untouched!

sg.ShadowQuality 0
sg.TextureQuality 0
sg.EffectsQuality 0

Or use: Edit > Project Settings > Engine Scalability

3. Kill Real-Time Updates

 

Why it matters: Sequencer forces real-time rendering by default, constantly updating shaders/Control Rig even when you’re just posing.
How to fix:

• Click on circle with 3 line icon on viewport(Where you set fps stat)

• Click the “Override Real-Time” icon (looks like a monitor with a slash) in the toolbar.

• Uncheck “Real-Time” — now your GPU only updates when you scrub the timeline.
  Bonus: Use Curve Editor for polish — no real-time needed!

Click the “Override Real-Time” icon in viewport settings:

; No code needed - pure editor workflow fix

4. FPS Lock for Posing

Why it matters: Animators don’t need 60 FPS while posing. Capping FPS slashes GPU workload.
How to fix:

• Press ` (tilde) to open the console.

• Type t.maxfps 10 (or t.maxfps 8 for weaker PCs).

• Preview animations smoothly later by typing t.maxfps 30.

• Reset with t.maxfps 0 (unlimited).

t.maxfps 12  ; Set max FPS
t.maxfps 0   ; Reset to unlimited

5. Light Complexity + LODs

 

 

Why it matters: Simplifying what your GPU renders = instant cooling.
How to fix:

• In the viewport, click Lit > Light Complexity (or Unlit for max savings).

• For characters: Force lower LODs (Level of Detail):

  • Select your mesh, go to Details Panel > LOD Settings > Auto LOD, set to 0 or 1.

  • Use Proxy Meshes for background characters.

r.ForceLOD 1  ; Force LOD level 1
r.ForceLOD 0  ; Reset

Switch viewport to Light Complexity mode while animating.

Final Tip

Your PC isn’t broken – Sequencer just needs smart optimization. Use these codes/workflows to stay cool!
