Fit the wing on the car rather than the computer maybe? Everyone knows wings on computers only cause drag anyway
In all seriousness though, I'm not sure what you mean. There is no way to change the shape of a LFS car without changing *certain files*, and that wouldn't cause any slowdown in the computer. Discussing those kinds of things are also kind of a grey area around here, especially as a demo user
Ah...maybe it's causing either the internet to lag (if online) or else the PC has low FPS when playing (which to an onlooker could be perceived as slowing the computer down)...That's all I can think of, I'm fairly sure it's the word "wing" throwing it off too
Not to worry on the English, it's better than a lot of people's. Just an odd word or two a bit wonky, but it's still better than average
