Mac Performance & Known Issues

A controlled Mac setup and performance-diagnosis ladder for MetalFX, frame generation, displays, saves and current issues.

Mac performance must be evaluated against the exact Mac model, chip, memory, macOS version, display and game build. Do not translate PC GPU tiers or driver advice directly into a Mac recommendation.

Verified technology boundary

Pearl Abyss officially lists MetalFX Upscaler and Frame Generation support on Mac. PC-only AMD, NVIDIA and Intel driver packages do not apply.

Establish the baseline

Record:

Mac model and year;
Apple chip and unified memory;
macOS version;
launcher or store;
current verified patch;
internal or external display;
resolution, refresh rate and HDR;
graphics preset;
MetalFX mode;
frame-generation state;
exact test route and duration.

Confirm the Mac meets the current official requirements.

Tuning ladder

Start from a stable preset.
Test on the intended display resolution.
Establish performance with frame generation disabled.
Select one MetalFX mode.
lower the costliest settings one step;
repeat the same route;
enable frame generation only after base frame pacing is stable;
test an external display, HDR or high refresh rate separately;
save, quit and relaunch before accepting the final profile.

External display diagnosis

confirm which display is primary;
record scaling and refresh rate;
test the internal display once;
disable HDR temporarily;
avoid changing the cable, dock, resolution and game preset together;
check whether the issue exists in screenshots as well as on the physical display;
reconnect the external display only after the game is closed.

Thermal and memory symptoms

Long sessions can behave differently from short tests.

repeat the route after the system reaches normal operating temperature;
close memory-heavy applications;
record when stutter or slowdown begins;
compare the same scene after a clean restart;
do not infer a thermal cause without temperature or repeatability evidence.

Crash and input procedure

Preserve saves.
Restart the game.
Restart macOS.
confirm game and system updates;
remove overlays or capture tools one at a time;
test the same action;
check Current Known Issues;
report the Mac model, macOS, patch, display, settings and steps.

Do not delete save data as a troubleshooting shortcut.

Save and Cross-Save protection

Create a new manual slot and allow the platform cloud operation to finish before moving the save through Cross-Save. Verify timestamps and progress on the destination before continuing.
