We recommend using a desktop PC with FOVE, it is possible to use FOVE with laptops, and many have done so.
If your laptop meets spec (see What are the minimum PC requirements of FOVE 0?), then you will have enough power to run FOVE.
The main trouble is that many laptops that meet spec have two GPUs (such as NVIDIA Optimus laptops). If the internal GPU is connected to the integrated graphics card instead of the discreet GPU, then the NVIDIA/AMD driver will not be able to enter direct mode for low latency rendering.
High end laptops such as most gaming-branded laptops have muxing capabilities on their main board that enable either card to access the HDMI directly. However, this is typically not written in the spec-sheet, so we recommend testing before you buy, if you can.
Any laptop advertised as VR-ready will work fine. We've found that "gaming" laptops also work even when not specifically advertised as VR, and that non-gaming laptops typically do not work.
If you purchased an Optimus laptop, you should set the discreet GPU as the default GPU in the NVIDIA settings in Windows before using FOVE. While FOVE's compositor will correctly use the discreet GPU regardless, most applications, including Unity applications, will launch of the default GPU, which is usually the integrated GPU.
One final concern is that many HDMI adapters don't function with FOVE, so we recommending finding a laptop with an HDMI port.
