I have tried everything, installing drivers without the secondary GPU, trying to reconfigure X11 and etc, is there any way I can confront these issues? Steam does not seem to have the same issues and I played Assassin’s Creed I at very unstable framerates because of this. I just realised that it could be my dual GPU setup causing this and I decided to remove the secondary.
Both of them are Pascal GPUs, one is a GT 1030 (my old card) and my GTX 1080Ti my new card (at least after I upgraded).
Before the upgrade I was using an HD 6450 as a secondary.
Ask me more questions, I will be happy to provide you with more details.
Thanks for reading.
