I've looked through various community forums, but I couldn't find any solutions related to using Bandicam for recording in Forza Horizon 4. Despite attempting to toggle DX12 and UWP hooking in the Bandicam advanced tab as suggested on the Bandicam forum support page, I haven't been successful in getting Bandicam to record in the game. Interestingly, I've had no issues using Bandicam to record in other games like Forza Horizon 3, Forza Motorsport 7, and Forza Apex.
If anyone else has encountered this problem and discovered a solution, I would greatly appreciate your insights and suggestions.
