Also... one other thing which makes me think it is my nvidia graphics drivers/settings/card is that I also see flickering on the ac tags at certain ranges too! Not noticed this on Replica before but maybe I've not concentrated on it. Turning clouds on/off seems to reduce the tags flickering but it still happens. The flickering of both clouds and aircraft appear to happen at mid range. Anyway, here is a video of the Tags (and ac) flickering; go to 27 seconds into video to see flickering tags:
I filmed this video using the default global Nvidia settings which are:

I did double check I don't have a custom Nvidia setting for CoD anymore (I did a while ago but when I was first trying to fix the flicking ac problems I deleted my nvidia control panel and drivers - didn't help - but did remove an old custom CoD profile under Programs tab). Whilst CoD isn't listed I do get a Steam profile:

These are the default Nvidia Control Panel Settings for Steam:

Sorry for the long post(s), any help would be greatly appreciated, I'm at a loss as what do to. Cheers.
