🔧 Current STOPS
Changing the RHI (Rendering Hardware Interface) works fine during runtime, but the change won't persist after closing and reopening the game manually. To ensure the selected RHI loads correctly on launch, we use the RHISwitcher.ini file. This information can be paired with custom launch options—such as Steam's launch parameters—or by starting the game via a .bat file or any custom idea you may have.
⚠️ Important:
If you want to switch to Vulkan, make sure Vulkan support is enabled in your project settings. While the switch itself may technically work, the game will display an error if Vulkan support hasn't been explicitly enabled.
------------------------------------------------------------------------------------------------------------------------------------------------------
⚠️After changing the RHI, the RHISwitcher.ini file will take 30 seconds to apply the change. If a crash occurs within that time, you're safe.⚠️ Change this time SafeModeTimeoutSeconds=30 Will take effect when closing the game in the time specified here.
