Also server side raytracing is not that computationally expensive considering all you're doing is comparing positions of players and maybe simulating a bounce or two in 2D space.the only time it'd be that bad would be in games like fortnite/pubg where they want the massive sightlines. So instead just do the rt check in a radius from the player that coincides with fog/draw distance

I agree with you, I think game dev isn't easy but these solutions aren't difficult either. It's just, Why try and fix what ain't broke and your company already likely has a contract with anti cheat providers like Denuvo.

Server side anti cheat is a viable and smarter solution, we have more than enough computational power to run it. So lets stop making artificial walls between platforms and enjoy playing the game
