No, the afm/pfm were design to be used with no curved axis (1:1)
I never used curved and it's perfect
For DCS you need to have decent hardware (change it, if your's is defficient, "like you said")
For noobs perhaps, but it's not a good idea, it's like "labels", it's better to start without.
But you seems to be newcommer, then i can understand your POV.
My advice is :
No curved axis, training, training and ...training.
