Trade-offs

Questions about Terder's Potato Shader.
3 questions
Is Terder's Potato Shader good for low-end PCs?
It is designed for that. The creator describes very low vertex and fragment complexity, no unnecessary post-processing and quick loading, aimed at weak hardware and older laptops. Actual frame rates depend on your machine, and the newest file is still an alpha, so treat it as a lightweight option to try.
How do I install Terder's Potato Shader?
Install Iris first. Then get the .zip from the file section, open Options, Video Settings, Shader Packs, and click Open Shader Packs Folder. Drop the .zip into that folder and select the pack in the list. Nothing needs installing on a multiplayer host.
Which Java versions does Terder's Potato Shader support?
It supports Java releases from 1.21.10 to 26.2 on Iris. It is not available for Bedrock, because Iris is a Java-only mod and Bedrock uses a different shader format.
