Only when I'm in game this happens. So while I'm playing a game the units and surrounding landscape looks as if it is shrouded with fog not like the fog of war, but like an actually foggy appearance over everything but the HUD.
I'm getting this too. It looks like all my graphics seetings were set to low with everything off, and resolution sampling is at 50%. I can't change this in settings, it just seems to be stuck this way. But this game is unplayable until this is fixed, it's so blurry I can't make out units etc.
You just need to set "Resolution scaling" to 100%. At moment you have downsampling enabled so basically game render everything except UI in twice lower resolution and then upscale it. This option was implemented for really low-end PCs
Yeah the thing was that it was automatically set to lowest settings with 50% sampling and the game settings couldn't be reverted and saved once was in game - something wrong with the 'save settings' button or with the client not recognising that I changed any graphics/resolution settings. I fixed the problem by saving the settings in the menu and it worked. I hope this helps the OP.
