Try uninstalling and then cleaning your GPU drivers with DDU. Download and install latest driver from Nvidia.

I don't know for sure but I think that Ashes supports only 2 cards atm. I would also expect to see perfomance improvements with 980ti+280x but I may be totally wrong. One thing I know for sure is that with AMD FX CPU I have absolutely no gain using 2xR9 290s over one. Maybe AMD cpus are just bad running this game or there is somekind of work to be done in that front.
That one file that steam keeps redownloading is likely just the settings file. Try disabling SLI in the drivers. Have you overclocked your system? If so reset any changes. You can try uninstalling GPU drivers and using DDU to clean the drivers completely. Then install the latest drivers available.
Not like that.. I had a line surrounding just the very edge of the map and for some reason its now gone since the hotfix. Maybe it is just present on certain maps. EDIT: They appear to still be there. It must be map specific or just random bug.
I have that flickering blue on the edges of the map but never seen it anywhere else. Thats been there as long as I have owned the game.
Suggestion number one is a solid one but I do not agree with the rest of the stuff. What I would like to see is the ability to drag build stuff like quatun relays and fatories.. Maybe Have extractors work the same way. Select engineer select area and it would build on every deposit automatically. I quess I did not read OPs post very well since drag and build is already listed.
Wow I made it to the list. But seriously I play ashes on and off and cannot really say I have never played versus a cheater. There have been some strange issues where enemy units do not die due to the lag but other than that it has been pretty standard. BTW why aren't more people playing ladder matches?
Are you hitting your logistics limit? You need to keep an eye on that and upgrade if necesary.
