About the solution for automatically exiting the game and high-end graphics card error and unable to play the game normally. This problem is not caused by the login device! The client machine with this problem is playing the old EI, or any other server will report the same error! In fact This should be solved by Korean developers. Simply put, the compatibility between Mir3.exe and DirectX9.0C is not good! This problem is not caused by the login device. The possible cause of this problem is the compatibility between the system Directx and the graphics card. In this case, only The graphics card driver needs to be replaced. The common phenomena of this problem are: Card Situation 1: The player cannot move. After a small retreat, the game returns to normal. Card Situation 2: The player cannot move and is bounced back to the desktop. The game returns to normal again, but repeatedly. Appears irregularly! Card Slot 3: The player cannot move and is bounced back to the desktop. The player still cannot move after re-entering the game (note that it is separate from the phenomenon of overweight baggage. Overweight packages will not pop up on the desktop). Card Slot 4: The player cannot move and is bounced. Go back to the desktop, go back to the game, and click on the checked interface. After entering the game, you still can’t see the image clearly, and it’s bounced back to the desktop! You can’t play the game normally! Mid-term solution: 1. Replace the nv4_disp.inf file with the 6693 version driver. 6177 file with the same name, then uninstall the driver of the previous NV graphics card, click Properties from Device Manager>>Standard VGA Display>>Update Driver>>Manually specify to the 61.77 driver directory where the nv4_disp.inf file has been changed. Installation is complete However, it is best to restart after installation. (Note: You can directly install the 6693 version driver and try it first.) 2. Or use 75.90beat, which has not passed the certification, to solve this problem, but there will be texture errors in World of Warcraft. Friends who do not play World of Warcraft recommend using 75.90. After all, the 75.90 driver is still much improved in graphics card performance compared to 61.77. 3.A card users please use: ATI Catalyst 5.3 (CP) version driver.
