64 hz Server Patch is a small edit to the game executable, required only for server hosts and affecting all connected players. This change forces values that were previously only customizable for LAN servers, now on servers hosted on NovaWorld. With the current speed of providers, everyone can now enjoy the game to its fullest.

This patch does not magically eliminate lag, the latency generated by your joining-player distance to the server will still remain. Players with high distance-based ping, will still need to shoot infront of their enemy, but they will have naturally less packet loss as the server will refresh at a much faster rate, leading to a significant reduction in the perception of lag.



What are the benefits and practical effects of this community server patch?

1. A huge decrease in the number of situations where players would teleport while moving, making perceived enemy player movement smoother and easier to aim at.
2. Now all bullets from all weapons on the server are more effective. Previously, 1/3 of the bullets of all weapons (e.g CAR15) were eaten due to the default low server data refresh rate of 16 hz.
3. All in-game sound effects can now be heard audibly. At 16 hz, many gunshots and ambient sounds were not played because they started at times when there were no packets to transmit to the player joining the server. Now all players can hear weapons, vehicles and the environment in their real accurate state.
4. All of a player's mouse and keyboard inputs are transmitted faster to the server, making it easier to execute movements they've really wanted to do on the server. Easy to notice when a player prones.
5. While it doesn't lower the minimum ping your players can have on a server, their ping tends to not fluctuate as much as it used to.
6. Movements made by all vehicles are now smoother and synchronized, making it possible for a player e.g. To hit another player who is in the window of a Black Hawk with much less difficulty than before.
7. Maps load much faster for everyone.

Video comparing 16, 48 and 64 hz:

Why did NovaWorld's servers run at 16 hz and why should we use more than that?
Limitations of the time the game was developed culminated in methods and adjustments to accommodate players with slower connections such as dial-up. Today, everyone plays with connections capable of handling higher refresh rates, so there is no longer any need to degrade gameplay quality. No more players teleporting for no reason.

Why we shouldn't use more than 64 hz?
Although we can go further and reach 128 hz and we've tested higher limits, the game is not prepared for this and may present some problems in animations and other things. 64 is the sweet spot, perfectly matching the frame rate at which both the server and the game is designed to run on natively. This rate is also in line with current gaming standards, allowing new players to have fun and not be negatively impacted.

Compatibility
This patch is not compatible with modifications that also change the game executable.

Good stuff! Love the explanation and demos Keep it up!

Will this be modified in the future to host Coop maps on DFBHD and DFBHDTS ?

[Badger]

I assume we keep a copy of the old dfbhd.exe file if we want to convert back to the original. Are there any other files besides the exe that changes with this new 64 exe?
This way we can keep a copy of them along with the dfbhd.exe.

Great job you guys!
