2 players on one PC without lags

So i would like to play with my brother on the same PC, I manage to start and run two games in the same time. Also playing both games with different controller but the issue is here if i click in one citra game, the other citra window (Game) lags more.

System Information

  • Operating System: Windows 10
  • CPU: Ryzen 5 51600
  • GPU: GTX 1070Ti
  • Citra Version (found in title bar): Citra Canary 2647
  • Game: Pokemon

This is normal. Your GPU driver will prioritize the focused Window. That’s just standard Windows behaviour. We can’t do much about that.
