For me to investigate further, please share the additional information below.

1. Have you tried running these games without WeGame launcher?

2. What WeGame version are you using?

3. Does this happen with other WeGame games or only Valorant-CN/Delta Force-CN?

I look forward your response.

Hello WEmwuZ

Thank you for taking the time to share all this information. I understand that the 32.0.101.7026 driver initially worked well for you. However, based on the new details you've provided, it seems that the same issue might also occur with this driver. Could you kindly confirm if you're now experiencing the issue even while using the 7026 version?

I look forward to your response.

Best regards
