Troubleshooting a Discrete GPU: When Games Won’t Launch

If you’re experiencing issues with your discrete GPU, you’re certainly not alone. I recently faced a frustrating situation where my GPU was recognized by Windows but wouldn’t launch any games. This post serves as a guide for anyone encountering similar problems, as well as a solution that might help.

The Problem

Since yesterday, my desktop wouldn’t run games using the discrete GPU, despite it being detected by the operating system. Curious if anyone else had experienced something similar, I figured it was time to reach out for some advice.

• Integrated GPU Works: When I switched to the integrated GPU, everything operated normally, but the performance was painfully laggy.

• Discrete GPU Issues: However, when I attempted to use my discrete GPU, crashes occurred right at the start-up phase of games. Typically, they hung on the initial white or black loading screens. I did manage to get Genshin Impact running on a couple of attempts, but the trouble persisted during the launch phase.

The Solution

After some troubleshooting, I uncovered the issue: my monitor was connected to the motherboard’s video output, not the discrete GPU. By simply plugging the display into the dedicated GPU output, every problem was resolved!

Conclusion

If you’re faced with a similar predicament of a GPU that seems functional but won’t launch games, check your connections first. It’s a straightforward fix that could save you a lot of time and frustration. Don’t hesitate to share your experiences or solutions in the comments below!
