I recommend using an AMD CPU and GPU, but otherwise you can just assume a game works and it will most of the time. If it doesn't, there might be some quick fixes, and if not then it's an unlucky one.

See ProtonDB.

My GPU is not able to drive anything of that sort hahaha. But the monitor was much cheaper than it used to be so I thought I'd snatch it and wait for a few months until I buy a new rig.

I have big hands so I'd have to go with the Xbox 360 and Xbox One's controller. The DualSense is very good, too. I'd give it to the DualSense for the haptic feedback and vibrations, but they're both great!

I'm thinking it was due to the fact it was revealed during Xbox Showcase.

Two things this will depend on - what are your system specs, and what games do you play.

The thing is my PC has really old specs. But I saw the monitor heavily discounted so I thought I'd snatch it even if I can't really use it properly for a few months.

May I know which 4k/165hz monitor you got?

For controllers and small devices like this, they could just go with standard AA batteries like Xbox's.

I'm not sure if the manufacturer will be required to make the replacement batteries themselves. For older laptops, you could buy an external battery from a 3rd-party which worked just fine.

I disagree with this. I'm all for federated and non-corporate alternatives but I think we should post the source and not an alternative front-end. Those that want to use exclusively those alternative front-ends have access to browser add-ons that automatically redirect them.
