i have a g2 and a rtx 2070, tried many things, but what works for me at the moment is i run steam vr at 50%, i then set dcs application to 200%, the allaising you speak of really improved for me , i fly the ka50 atm so might not work on fast jets aswell but worth a try, i also have msaa on in nvidia control panel, but do not use the aa in dcs.
