Refrax is a performance and feature-oriented Minecraft shaderpack for Iris.
NOTE: This is for v1.3.0:
| Profile | Target FPS |
|---|---|
| Potato | 120+ |
| Low | ~90 |
| Medium | ~70 |
| High | ~55 |
| Very High | 40+ |
| Extreme | 25+ |
| Overdrive | ~20 |
NOTE: This is for v1.2.2:
| Profile | Target FPS |
|---|---|
| Potato | ~160 |
| Low | ~120 |
| Medium | ~80 |
| High | 60+ |
| Very High | 40+ |
| Extreme | 25+ |
| Overdrive | ~20 |
NOTE: Both benchmarks were taken using the exact same scene.
I saw a ~25 fps boost on 1.18.2, 20+ fps boost on 1.20.1 and ~15 fps boost on 1.21.1.
These values can be bumped higher by changing the performance mode slider at very little visual compromise even at overdrive performance mode (You'll only notice it in certain situations. It mainly reduces the sample count of clouds, god rays, AO, SSR, and water wave octaves, most noticeable of which are reflections and water which will be tuned to be less noticeable in the future).
1.18.2 and higher versions should all work just fine.
1.16.5 - No colored lighting and no block breaking particles. 1.17.x, 1.18 - Does not load the shader 1.18.1 - Does not render a lot of blocks.
