Hi.
I just want to add this video of a mod for the mrc scope that an Arma 3 modder made:

This proves it is possible, and can be implemented without massive frame rate loss.
I'm all for this idea!
It would make the game so much more immersive and enjoyable!
Cheers

Sorry for the delay in updating details.

I found out the easiest way to recreate the problem...

This is a particularly big problem for tracked vehicles.
At least when you get some air time in a wheeled vehicle you continue forward at the same speed when you hit the ground. In a tracked vehicle, just going over a sufficient mound or bump at speed will cause the tracked vehicle to nearly front flip and slow drastically.

I agree.
If you look up videos of modern tanks such as the merkava mk5, they do not struggle to get up hills like the slammer on Arma 3 does.

Sorry,
My internet is terrible (Bad Satellite) and I cannot upload videos at the moment... You should be able to recreate the event on Arma 3. If you drive a tracked vehicle fast enough off a small cliff edge/hilltop then when it hits the ground it will appear to try to front flip, slow down greatly and sometimes slide before continuing on.
Cheers
Sorry for the inability to upload videos.
