Thorium’s entire focus is on performance. As another commenter has noted, that means no security updates, and no privacy features.

I wouldn’t recommend it for daily use, but if you are playing a browser based game it’s worth testing out. I used to play krunker.io and I tested it to see if I could get more FPS (FPS equaled faster movement speed back then), but I didn’t see any major performance improvements over the major krunker clients or Microsoft Edge (other most performant browser).
