I have a Galaxy S9+ European Model (so exynos processor and Mali GPU) I can run Luigi's mansion in 1080p no problem with OpenGl or Vulkan. With OpenGL when i vacuum ghosts or in specific places (Like Outside) the framerate drops to 18 from solid 30 It was. With Vulkan this does not happen anymore but the Torch Light and the vacuum Air don't have transparency anymore (Links Bellow for images). So in both cases these problems ruin my experience. Any help is appreciated.
