I find myself turning off the feature in dxvk.conf after applying the tool

# Allow exclusive fullscreen mode on Windows
# dxvk.allowFse = True

as per title issue. Is there any chance a toggle could be added or some freeform textarea where I can apply my own overrides?

Windows 11 Build 26200

Thanks for reporting this !
I’ve just updated the tool so dxvk.allowFse is now set to False by default.

This should prevent the black screen / slow Alt+Tab behavior without needing to manually edit dxvk.conf after applying the tool.

Fixed in commit 9b46d98
