Ok so pickiest post yet from me but meh.
So got a rMBP here and noticed a few things, all in the attachment.
The GG face on the forums that shows up in the tab is high res and looks spot on, for the LAN page its not, yea I know its still a wip but thought I would point it out as it should be a quick fix, i.e copy the image over.
Also the forums logo at the top looks blurry / scaled on retina screens, main site looks a little better but you can still tell its a low res image scaled up.
Also the forum smilies again look a bit pants on a retina screen.
Yea I know, small things, not really importent in the big scheme of things but now 4k screens are becoming affordable more people will be viewing the site on high res screens with the DPI settings set to more than 100% so it makes sense to update the images now so that things are future proof
No idea how the screenshots will come out, but I have attached them anyhow so you can see what I mean
