@ robertcrossland:
Just a guess, but worth to check wherher maybe something has changed in the Unreal Engine config, i.e. it might start in DX12 mode per default. That’s really just a guess though. Do you experience this with any supported game or just the Unreal Engine?
@ piperhawk:
Whenever you experience hooking issues that suddenly appear after a vorpX update your first suspect should be your AV program. There haven’t been any changes to the hooking mechanism.
Please try to exclude the vorpX program folder from your AV program. If you use anything else than Windows Defender, also consider uninstalling your AV program. Windows Defender will kick in instead.
