I have been having some difficulty whenever I was testing my vehicle handling in MP Preview mode. It was a complete disaster. The car was out of control going in random directions, teleporting at weird angles, rubberbanding and all that jazz. This has been an issue in some other games creators have published. Interesting enough, even the racing framework has the same problems in game or in the MP Preview. Speed Jump by Grunlock is a game plagued by this; a car parkour game with a vehicle that can't be handled. He made the game available for download and, in doing so, people get to enjoy the game locally without the lag.
Today I have found something really interesting though. Varglbargl published a game called Downhill Drifter D and mentioned that the game may function differently based on the framerate. I'll be honest, I have a potato PC (retailers are the scalpers in my country), but I can mostly run at high settings and this game was not having it. The car was doing its thing, rubberbanding, randomly bumping into walls, the usual stuff. I lowered the settings to the lowest and the car was fine, almost. It felt a bit weird, wiggly. After this revelation, I went back to my project and lo and behold... Bad graphics = car handles well, but it was still a bit wiggly .
I am wondering, is there a fix for this? I am making a map for the Traffic Jam, but I'm afraid players will encounter this problem and it will ruin the experience. Maybe I'll also lose some points because what is a the point of a map if you can't drive through it...
PS: Some creators get a lot of criticism for the vehicle handling even though it's not really their fault. (Kooky Karts by CommanderFoo for instance)
