For anyone hoping to play Delta Force on Desktop Linux, the developer Team Jade has given a pretty clear no. That's despite it working on Steam Deck due to the anti-cheat they've used.
I do think some of these limitations can be resolved. But it indeed poses a big challenge. You can go to big lenghts with server occlusion checking to prevent wall hacks but under zero trust any game with directional sound already has build in wallhacks.
I mostly speak from experience with my developing my own game which is not an FPS. Previously the client would send “i build on this position”. Which could very easily be abused. Which I then changed to “i build with this angle and this distance from the previous node” the client would then already show the newly constructed “ghost” node while the server would check if that construction is valid and then send the real position to all clients. The only thing a player would notice is that with high ping the constructed node would move slightly as it got the definitive position from the server. While being significantly more cheater proof.
I suppose im biased towards this kind of thinking since im not working on a FPS game, what for me might be a simple change is a massive undertaking for other genres.
