Depending on the bells and whistles you have turned on in advanced graphics, offline sitting on the runway in a P51D. Hold down on the trigger firing all guns with 10x ammo. You can watch your FPS drop by up to 30.
The current damage model uses a counter so we have hybrid ammo. Maybe with the change in graphics, the damage model will be changed, and specific result ammo will be possible.
I'm holding out for the possibility convergence and harmonization will be updated.
