Actually, if you’re interested, gaming on Linux is great nowadays.
Nvidia GPUs are not really well supported, but they work.
However, if you game using Intel integrated graphics or an AMD GPU, the performance is perfect.
On steam I have yet to encounter a game that does not run well using Proton.
About support: I have a Framework laptop. With my initial shipment I received a defective Ethernet expansion port. The failure was difficult to identify, but support was incredibly responsive and helpful. Once it was confirmed the issue was due to a defective Ethernet card (which took some investigative effort), a replacement was shipped immediately.
All this to say that, if you live in a supported country in the EU, I see no reason that people may find their support lacking.
