Thanks! What sort of spec is it? Processor, RAM, graphics etc.?
Also, did the game return to normal when the video ended?
Thanks again for this.
Yes it did return to normal. And the graphics we're kinda lowed down. But the speed has slowed down too. This is all I know.
Unfortunately, it may just be the specification of your computer. While RPG Maker MV makes games that look a bit like SNES RPGs, it actually has reasonable system requirements in order to run smoothly.
If you can tell me anything else about your computer's specification, that would be very useful.
