Just bought the game in Beta & have to say im impressed, I was sceptical of buying it so early due to my PC confiuration..
CPU = AMD 5GHZ 8 Core
RAM = 16GB 1800Mhz DDR3
HDD = 500GB MX200 Crucial SSD
GFX = 2x Radeon R9 200OC (Overclockers)
This is probably the only Beta game ive even tried playing & actually had NO issues with, Ive played countless games in Beta & had horrible FPS, stuttering, game drops & crashes, NOT with this game (so far) Runs very smoothly using Windows 10 x64 v1511
You guys seemed to have nailed it keep it up & cant wait to see more & ultimately play the Full Finished Game :)
Im posting this so if theres others out there with CrossFire configs that are maybe worried at least with this you have a base to run off as non of the Utube vids ive watched have been played using crossfire & its usually not optimised for that until much further along...
