Counter-Strike: Source Enhanced

Started from a fork of https://github.com/nillerusr/source-engine \ A huge thanks to him for having port most of the valve project generator stuff to waf.

How to build:

First install dependencies: https://github.com/nillerusr/source-engine/wiki/Source-Engine-(EN)
You also need zstd library.

To compile for CS:S Enhanced a command line can look like so: ./waf configure clangdb install -p -o build --use-ccache -T fastnative --prefix ../css_enhanced

• clangdb generates compilation database for LSP
• install installs into the prefix ../css_enhanced the binaries
• -T fastnative, compiler build the source code for a performance oriented release for your specific machine.
• -d for dedicated (server) build.
• -P <0-4> is to enable profiling with different levels, 1 is usually enough if you want to know what takes more framerate.

How to play:

You can join my Discord server at to get a release: https://discord.gg/e8nbakt8

OR:

• First, you need original CS:S & HL2 files.
• Copy the original CS:S folder somewhere
• Overwrite the hl2 and platform folder from the Half-Life 2 files so that shaders can work.
  This is because stdshaders needs some rewrite to make it work basically with sdk 2013, can't do it now yet.\
• Run the game with hl2_launcher(.exe) -game cstrike.
• I have my own server at cssserv.xutaxkamay.com, when it isn't down.

What was enhanced:

A lot! If you're curious you can look on the commit log, but here's the most interesting things:

• Trigger prediction, output event prediction. (this caused the player's mistmatching between server and client)
• Local player interpolation fixed without doing sub-ticks. (this is known as your screen not matching the server/client's tick view)
• Lag compensation fixed. (Animations are server controlled now)
• SetupBones being different from client and server due to the fact that IKs weren't enabled.
• No autobhop lag.
• fps_max 0 is possible now without speedhacking. (you can get more than 1k fps)
• More performance in general, for example in Windows, I removed the legacy input system that took around 300 fps in fullscreen.
• You can use ARM servers to run a dedicated server (this is huge, since servers have a lot of power consumption).
• Network compression mostly removed so the client get the exact values from the server
• zstd compression with trained data so that it compress (and decompress) very fast for a very good ratio. (around 1/10)

And more to come (TODO):

• New weapons coming, thinking gluon gun & m82a1
• Shareable skins where you can use your own skins and other people will see them.
• And much more to come ...
• Replay
• Source TV and recordings that can display the exact things that the player has seen on his screen by re-using lag compensation.
• Hit indicator
• A timer
• m_rawinput 2 that aligns the angles to a tick.
• General bug fixes like edge bugs, surf ramp bugs ...
• Sphere/cylinder hitboxes
