I bought a taru with the intention of sling loading our Hemtt Transports, but the covered variants can't be slinged? Is that a bug or a server feature? You can load them in vanilla.
I've got a 2070 super, ryzen 9 3900x, 32gb of ram.
My old pc had a 1080, some shitty intel processor, and like 8gb of ram.
My cousin has a Ryzen 9 7900x, 32gb DDR5 RAM, a 4090.
They all run Arma the same. It's a poorly optimized game in my experience and it's just a game of guess and check until you find settings that let you hover around 60fps.
