I have gotten to 9.843591 E^128 knots in X Plane 11. I used an aircraft I made that is basically a skewer with rockets and fins that is 50 feet long. I got that speed from the last frame my game made before it shut itself down from a physics overload.
I did an FH4 round of the Super7 game mode added yesterday with the Jesko, an absolute beast of a car and hit 295, the second fastest i've gone
310 mph in a drag Corvette in The Crew 2, but I actually count it cause that game isn't all that good, and it's probably the one game I genuinely regret buying full price. The record I do actually count is 302 in FH4 in a TVR Speed 12.
