Having done this myself, multiple times (I write a lot of graphics code and like being able to test stuff on AMD, Nvidia and Intel GPUs on multiple operating systems without having to switch physical machines), it's a huge hassle and frankly if you just need a Windows machine to play games on occasionally a dual boot setup is way more convenient, not to mention less buggy.
There is no reason that you couldn't, for instance, bind-mount the host's nvidia drivers into the container namespace when launching the flatpak. Would avoid having to download the driver again, and reduce runtime memory pressure since the driver code pages would be shared between everything again.
A huge chunk of Linux development is subsidized by the hundreds of corporations which depend on it and pay developers to maintain things. There is no corporate interest in developing and/or maintaining an alternative browser engine when chromium already exists and dominates the market.
