Alpha Piscium ships with six built-in quality profiles that act as one-click presets, simultaneously adjusting shadow resolution, GI sample counts, denoiser settings, soft-shadow quality, and more across the entire shader. Rather than asking you to tune dozens of interdependent settings by hand, profiles give you a coherent starting point tuned by the author. You can always override individual settings after applying a profile — the profile is a starting point, not a lock.
Ultra is the intended experience. The author designed Alpha Piscium’s look and feel around the Ultra preset. If your GPU can sustain it, start here before experimenting with anything else.

Available Profiles

ProfilePriority
LowBare minimum rendering. Potato mode — not recommended for normal play. Disables or minimises most advanced features to squeeze out frames on very weak hardware.
MediumBaseline performance mode. Enables core features at reduced quality, suitable for mid-range hardware that cannot yet reach High.
HighBalanced quality and performance. A practical everyday preset for mid-to-high-end GPUs that want good visuals without a heavy frame-time cost.
UltraThe true Alpha Piscium experience as it should be. Full-quality GI, shadows, and materials at settings the author considers correct. Recommended as the default starting point.
ExtremeAn even better experience at some cost. Pushes sample counts and denoiser history beyond Ultra for noticeably improved lighting stability and shadow fidelity, at a meaningful GPU performance cost.
InsaneMaximum quality. Every configurable knob turned to its highest setting. Intended for high-end hardware, benchmarking, or screenshot work rather than interactive play.
Selecting a profile overwrites all affected settings with the profile’s preset values. If you have made manual changes, applying a different profile will reset those settings. After choosing a profile you are free to tweak any individual option — your changes persist until you apply another profile or manually reset them.

Choosing a Profile

Start by applying Ultra and checking your frame rate. If performance is insufficient, step down to High, then Medium. Only resort to Low if no other profile is playable. Conversely, if Ultra runs comfortably and you want even cleaner indirect lighting with less noise, try Extreme before committing to the full cost of Insane. Because profiles touch nearly every subsystem — shadows, global illumination, materials, post-processing — they are the most impactful single change you can make. Fine-grained per-category tuning (shadow resolution, GI trace steps, PCSS sample count, etc.) is documented in the remaining configuration pages and is best done after settling on a base profile.
