Why is the game lagging?
Thanks for checking out my game. I have to ask you to check out your recording software. Clearly the issue is on your side and not mine. I have seen over 100 videos of my game, all playthroughs. There were 0 issues with the frame rate. In addition, if you look closely at your video, even your face recorder starts lagging at certain point, which can't be the case unless your software is causing trouble. I wish there was a problem and I was to blame, but it is not. Copper Cube 6 is the "potato" engine from all the other game engines, because it runs smoothly on every PC even without optimization. Hope your software gets fixed.
Best to you.
