A 1050ti will work fine, VR doubles frames down to 45 fps to keep the headset at 90fps. Oculus was the first to use this rendering method, but now all headsets do it. I've personally used an Acer WMR headset on an Acer Nitro 5 with a 1050ti and it worked great, granted the fans on the thing were SCREAMING, lol. Will it be 100 percent max detail? Probably not, but when I tried it, it seemed fine, maybe a bit less detail compared to my Samsung Odyssey+ on a 1080ti.
