OK! I have a GTX1660 TI hope that I can improve something again because the 460 series doesn’t work at all !!
Does anyone know, where i could find older versions at the nvidia homepage?
I am still using 452.06 Version on a RTX 2080 Super and this is performing very well for me.
I bought FS 2020 at the second day it came out ( Store Version Deluxe )
and since i never had a CTD or something like that.
I dont belive i get a real better performance with a newer Driver so i leave it like that - i am lucky with it. I have a lot of long hauls flight ( at the moment with a 747-8 13h 35m ) and never had problems so far. Dont wont to risk anything with a new driver Installation…
To say all on 4K.
But i think if you use a 3080 or 3090 card you have to use the newer driver because of the support to that cards.
cheers 
There is still issues on 457 but its certainly less.Sometimes I wonder what Nvidia is doing with the older cards.I will be sticking with 457.30 for now.Or something is wrong with the sim.
Thanks
