Don't really know much about VR.
I have Xiaomi Redmi 7A (not sure if even support VR as it doesn't have gyroscope - but if it does what else do I need to buy (cheapest possible) to try LFS in VR?

And if not - what is the next cheapest option?

My PC specs:
AMD X6 FX-6100 @ 4.0GHz
NVIDIA GeForce GTX 750 Ti
8GB RAM

Thanks.

I know your graphix card won't be enough.

I have GTX1060 6Gb with HDMI connector, and that works ok.

Look HERE for good idea of what's required for VR.

One thing I didn't realise when I got Oculus Rift CV1, was that 3 x USB3.0 ports are required. I had to buy external powered 4xUSB3.0 hub for all the connections.

I will buy a cheap VR BOX which will use with my smartphone - just to try the VR feeling.

- EDIT -

Just ordered it - more information when I get it - will post a link with the model of the VR glasses and how to make it work with LFS.

You can always try VR in a place where you can demo VR headsets, but they probably don't have Live for Speed.
