in my case it freezes when i move the statistics tab from the newspaper, 500p map,
regarding specs, i highly doubt that running the Supremacy 1914 500p map on Chrome requires more than Battlefield V at Ultra, so no need for that.
I doubt battlefield is a browser game? If you have to built a local program you can use a lot stronger programming. When you program for the browser your programming is a lot more limited with only since shortly (for supremacyc) acces to the GPU. I do however get your point however I fear it's not that easily mapped on one another.
