I play things like satisfactory, tf2, portal, doom stuff. But I am too old to play anything where reaction time really matters all that much. Like tf2 I only play mann vs machine now. My monitors are just 144hz. Nothing too fancy. Though I do have 2. And I forgot about VR. I want to get one, but I have no idea if linux supports them or how much the graphics card matters these days.

I’m guessing boot to a USB and run some kind of repair utility?

So if they are on different disks, does that keep windows from eating the linux bootloader? Also, do you use something other than UEFI to manage which OS boots? Seems like a lot of people just use UEFI if things are on different disks.
