Hey RichUK! Did you manage to get a new GPU for running modern Arma properly?
Arma Reforger seems to be shaping up pretty nice now. This week there's been a big update on the Experimental branch of the game, so it's worth to check it out (they've added weapon resting, a proper medical system and whatnot).
I'm up for going on a session of Arma Reforger, if anybody here fancies it here, too. Haven't played it in a while, but as mentioned above, the recent update on Experimental branch is awesome and very promising.
