In Mint, from the start menu you can right click on the app you want to run and from the drop down menu you can select to launch with dedicated GPU. Otherwise left clicking will launch with the integrated GPU as normal.
From the other comments, it looks like it may be an ubuntu issue so I'll consider another distribution and maybe things will run a bit smoother in general.
You indirectly answered another question that got lost in my head. I'll add those commands to my cheat sheet so I can attempt to diagnose problems myself in the future.
I may just switch to another distribution in the future when I have the time. I think I'm also traumatized by windows.
Usually I have to schedule an entire day reformatting and updating windows. Compared to setting up Mint the first time which took maybe a couple hours. A lot of that time was going through the settings just to set things to my preferences.
Still can't shake the feeling of dread about installing a new OS when deep down inside I know it's not so bad hahaha
