I know this is the old story, but I could not find any updates on it on the web. Everything is like at least two years old. So I've been running 1070 for some time until yesterday my friends gave me 2 xVega 56 from his mining rig as he is making some changes and he does no need them, at least for now. I plugged them in. Enabled CF. Seem to work in other games just fine. In Star Citizen they just crash whole my PC beyond a simple CTD. It is either a full freeze of PC, or GPU driver crash to the point everything fails and I need to restart anyway. I know from my orgmates SLI is possible. And it indeed give you a very good FPS boost if tuned correctly. Problem is I have zero info on Crossfire. I don't put in too much hope into it, knowing I'm pretty much stuck with one Vega non CF, still if there is a person who know any solutions or W/A to this please let me know. Will be greatly appreciated. SPECS: CPU: i7 - 4790K RAM: 16GB DDR3 (upgrading it to 32 in few days). MB: Z97 Gaming 5 Storage: SSD
