I'll look into it, but from what I've been told this looks like it might be a hardware limitation - I'll try to find a workaround for the next release, but I might have to disable motion blur for certain devices.
That’s expected since this device is pretty old, but for future i think a message should be provided. Something like “your device’s graphics is not supported”. And if you have the time and those specific shaders aren’t necessary you could make it optional with default on, and off when detected not supported, i will try the game on my computer and give you a proper feedback for the actual game, thanks for replying.
