Not unacceptable, unacceptable for me (something that should have been clear in the post you referenced) it is entirely subjective. Personally I don't like the graphical glitches ASW introduces BUT I do think its an amazing bit of tech. I find the glitches are very obvious from the hud shimmer / wobble when your ship rotates on the landing pad (which also affects the thinner framed cockpits such as the vultures) and when turning in your SRV to the tell tale hitch of ASW kicking in and stopping.
ASW is there to pickup the occassional dip in FPS, it's not ideally to be used to punch above the weight of the hardware you have. Although many do, which is fine if they're happy doing that, get results they're happy with and can overlook the issues they will get by doing it.
Anyway, glad to hear you worked out the issue OP. Those original settings did look a little on the high side to me and even ASW can only do so much.
Thanks mate
