compare
GeForce RTX 3060 Ti use time 1 second
my GTX 1050 use time near 1 hour for scan all key space
Can possible to print out key if not use options output
or print both may be safety
Scan found key but not use -o out.txt for save it make mission key
Also, since you are using a 1050, you should be able to use full address and gain speed.
