Windows

Windows Download

Troubleshooting

Check logs first

PatchOpsIII generates a PatchOpsIII.log file and prints live status messages in the embedded terminal.

Launch options are sensitive

Launch option behavior can vary across systems. Apply changes incrementally and confirm each option is stable before stacking more.

Config safety

If you use the read-only toggle, remember to disable it before making manual edits to config.ini.

FAQ

Do I need to keep t7patch running in the background?

PatchOpsIII’s T7 Patch management is designed to apply the patch and configuration cleanly; it does not require you to keep a separate patch process open for basic setup workflows.

Is DXVK required?

No. DXVK-GPLAsync is optional, but it can reduce shader compilation stutter by enabling async pipeline compilation through Vulkan.

Where can I request features or report issues?

Use GitHub Issues: github.com/boggedbrush/PatchOpsIII/issues.

Need deeper details?

The project wiki includes extended notes on each tab and option.
