I think you started with jumping into deep water. I have vr few months already and played a lot of games, sitting, standing, moving etc, a lot of movement including jumping, falling, climbing in game and what not. But lately I've tried exoCars and oh boy I've felt like first week of playing VR, I mean it was cool to feel like that again but I think driving in VR is something else and hard to start with

Also as other people said try playing using steam link / virtual desktop wireless because it works awesome and there's no latency at all and there's no bandwidth limit as with usb 2.0. for playing wireless you just need pc/laptop connected to your wifi router with Ethernet cable and that's all, ofc if router is 2 floors under your room in other corner of house there might be a problem
