The game is supposed to run at 60 FPS can you please check the gameplay video at https://store.steampowered.com/app/1048560/Voidrun/ and tell me if the game seems faster than this ?
To add a bit of detail, it seems that the game runs considerably faster with VSync turned ON. With it off, it seems to run at the same speed as the gameplay video on the Steam page. I have a 144hz monitor and a GTX 1060 6GB. This behavior does occur in the DirectX version as well. I just bought the game today and this behavior was experienced on Steam version 1.03.
