Hi! I saw some threads on Steam that is possible to launch the game with Vulkan instead of OpenGL by adding the "-force-vulkan" argument.

I am trying to do that with the GOG version through Lutris by adding it in the "Arguments" section without success. Does anyone how can I do that?

For anyone that has the same problem as I did, I managed to make it work by selecting the binary itself. Lutris, by default, was using the GOG shell script that checks if the system is x86 or x86_64, so I selected the x86_64 binary in "tower-of-time/game/TowerOfTime.x86_64" as the game executable and added the "-force-vulkan" as an argument.

The game has a much better performance now!
