What this mod does

IRIS 20/20 is a post-processing filter for Pure by xkandromeda, one of the newest and best-rated on OverTake. The author built it with performance in mind: no extra code slowing the game down, without giving up a realistic, attractive image.

What it offers

  • Realistic yet striking daytime colours and very colourful sunsets.
  • At night it pushes bloom a little for a cinematic look.
  • Works at any time of day and in any weather.
  • Works with Pure in Gamma mode (more cinematic) or LCS (more natural, with less glare).

Installation and version

Drag the contents of the zip into the Assetto Corsa root folder: do not install it through Content Manager. Then select the Pure Gamma (or LCS) weather script so it looks right. The author guarantees it will always be free; Patreon supporters get updates a week early. It is on version 4.1.1, from October 2026.
