Hello. I have a RX 480 crossfire, and I would like to inform you that the Shadow Warrior II game is not working in crossfire mode, it only works on single gpu. I already put it in full screen mode, tested with the drivers 16.11.5, tested with 16.12.1, and in both the game does not start in crossfire mode. Another problem I have is in the game Fallout 4, but this is in both single and crossfire. When setting the resolution to 1440p or 4k, the vsync of the game gets caught in the middle of the refresh rate of the monitor. If it's 60hz, vsync hangs at 30fps, if it's at 75hz, the game hangs at 37.5fps. This problem had also occurred earlier in older drivers. In full HD, vsync gets normal and works fine. I have done clean installation, downloaded the drivers more than once, turned off and reconnected several options in crimson and nothing solved. The configuration here is i7 4790k, 32GB ram, mobo Z97-E, windows 10 64 bit, aoc monitor G2460V.
