Despite me having a new PC i ended up using a Mario Kart Wii UHD Custom Texture Pack running at 8K Resolution and DX12 Renderer which turned out great so i got a idea to enable the highest values of max item limit modifier and item rain then activated both value to the Staff credits and it came out pretty cool and funny at the same time but it was a great PC benchmark though. When i set the max item limit values higher it actually removes some models including mii spectators and statues to reserve memory for the items instantly spawning in from the sky which is the reason why none of the mii spectators and statues are present. Also first video ever with the new PC and 4k rendering even though i recorded the game at 1080p 60fps OBS.
