Hello, I am very new to dualboxing. I have been playing the game for about 3 years and now decided to dualbox. I have been playing 2 accounts on one computer and was doing fine for a week. Then I started to have display problems, all my screen is covered with green checker board pattern. The graphic card I have is Radeon X700 PRO (I have been running the game with it fine before dualboxing). But now, obviously, I need a new card. I am looking for advice, do not want to overpay, I only run 2 accounts and not planning on adding more. Thanks in advance for your help.
