Ace Combat 8 ERROR 01 crashes: Native upscaling and memory checks

The Mission 28/30 upscaling case

Kerbal_Guardsman’s reply in the troubleshooting thread describes Mission 28 scene changes and Mission 30 hangar selection failing while using Ultra Performance upscaling. The player switched quality to Native and thought the crashes were resolved.

1. Record the exact point where your crash happens and your current upscaling setting.
2. If the case matches, save your settings and compare Native on the same scene.
3. Keep other settings unchanged for the comparison.
4. If the crash remains, retain that result rather than repeatedly treating the setting as a proven cure.

Native may increase rendering cost. The report does not prove which GPU, upscaler or engine subsystem caused the crash.

If you disabled the Windows page file

Enc0re’s Steam report says enabling virtual memory on the game’s disk stopped their crashes. The report does not document a universal required size. Check whether you intentionally disabled paging before changing it; do not assign an arbitrary fixed amount from someone else’s RAM capacity.

Microsoft explains that page files contribute to the system commit limit. Task Manager’s Memory performance view can show committed memory and its limit. Compare the limit with the failure scenario and retain adequate free storage if Windows manages the file. The Windows explanation is general OS behavior, not confirmation of a specific AC8 defect.

Black screens and unsuccessful comparisons

NindoBindo reports a startup black screen and ERROR 01 despite increasing virtual memory and clearing player preferences. Another reply combines paging changes with a full reinstall; that cannot identify which change helped. We do not recommend deleting all app data or disabling anti-cheat as a general repair.

For support, collect the error, launch-versus-scene timing, GPU and driver, game version, upscaling mode and the result of each single change. If flight is fine and only a cinematic stutters, compare the separate texture-setting case. First verify required hardware features.
