ARK: Survival Ascended – Fixed Render Thread Crash

How to Fix This

This is a fix for the famous “Render Thread” crash, which happens very frequently in some PCs. It took me 5 days of testing different console commands and almost anything.

Launch the game and then face to the ground to avoid crash.

Configure the settings on the menu:

  • Disable HLOD = ON (right down)
  • UI => Disable Menu Transitions (left down)

On console command type this:

ark.VertexCountScaling 1

You need to repeat this command every time you launch the game.

It works with all settings in Medium but you can set:

  • Advanced Graphics to High and
  • Effects Quality in High

For more FPS use:

r.VolumetricCloud 0

I’ve tested this extensively with fly mode and hasn’t crashed. My rig is an Intel i5 7400 with a GTX 1070 and 8 GB Ram. Ask is installed into an M2 SSD.

If you cannot get past character creation screen, launch your game with -dx11 as launch param in order to create your character. Then restart without any parameter!

I love games and I live games. Video games are my passion, my hobby and my job. My experience with games started back in 1994 with the Metal Mutant game on ZX Spectrum computer. And since then, I’ve been playing on anything from consoles, to mobile devices. My first official job in the game industry started back in 2005, and I'm still doing what I love to do.


  1. I’ve been having this crash since launch, just tried these commands and it actually works perfect without crashing at all, only downside is that i lose about 20-30 fps with the ark.VertexCountScaling 1 command, but worth it IMO.

  2. I’m the creator of this guide.
    Make sure you set:

    Global Illumination Quality: Medium

    GUIDE To avoid crash:
    Console command: ark.VertexCountScaling 1
    Global Illumination Quality: Medium
    Disable HLOD = ON (right down)
    UI => Disable Menu Transitions (left down)
