Well you have to know the model of your graphics card and your operating system. If you don’t know those things, you will have to either figure it out or download the app so it can detect that information automatically.
Yeah, that’s pretty basic. I seem to recall the option to even search by OS/GPU being fairly hidden, but again, probably just misremembering.
It’s the massive list of GPUs and all their variants that probably made it such a memorably bad experience.
