The Halo CE Ultimate Enhancement Guide - Updated 05/09/2019 (1)

A collection of every known tweak, fix, mod and patch designed to get the most out of Halo CE for modern PCs in 2019.

Halo PC Manual

Halo CE's latest official version is v1.10 (2014), and has 3 community patches:HAC 2(2016),OpenSauce v4(2015), andChimera(in active development). Open Sauce and HAC 2 are incompatible with each other, therefore it is recommended to switch to HAC 2 when playing multiplayer (adds map downloading), and OpenSauce when playing singleplayer (enhances graphics, and some maps require it). Chimera is compatible with both community patches and should never be disabled.

Serversdo notcheck your CD key! Both multiplayer and singleplayer work perfectly on any CD key.

"But what about Halo PC?"Halo Retail (PC) has been superseded in every capacity by Halo Custom Edition (CE). There is no longer any valid reason to play Halo PC over CE.

After you've completed this guide, check out part 2:The Halo CE Ultimate Content Guide

1. Update Halo CE

No previous patches required.

2. Run Halo CE's Redistributable

In Halo CE's root folder there is a folder called 'redist'. Run 'msxmlenu.msi' inside. This will enable in-game chat.

3. (Optional) Make Halo CE Recognise Your Graphics Card

If your video card was made post-2006, Halo CE will register it as ''Unknown'' in config.txt located within your Halo PC/CE folder. To fix this:

1. Double click Halo PC/CE while holding left Ctrl.
2. A small widow will appear with a code such as ''0x05e2''.
3. Copy this code and open config.txt in your Halo folder.
4. Under your graphics card vendor, before Unknown = "Unknown", create a new entry named after your graphics card, e.g 0x05e2 = "GeForce GTX 260".

5. Add the following:

UseAnisotropicFilter--Improves the quality of oblique textures (Alternatively, Chimera build 50 console command: chimera_af 1)

DisableBuffering -- Reduces input lag (Alternatively, Chimera build 50 console command: chimera_disable_buffering 1).


4. (Optional) Make Halo CE Recognise Your Sound Card

1. Go to Control Panel > Device Manager > Sound Controllers, right click and open the properties of your audio card.

2. Go to the Details tab and make a note of the 4 characters after VEN_ and DEV_ under Hardware Ids under Properties.

3. Go to config.txt in your Halo PC/CE folder. If your vendor is matched by an already-present vendor, create a new line underneath in the same fashion as the rest. For example, if DEV_AA01 is my device ID, I create the following line 0xAA01 = "High Definition Audio" beneath that vendor.

4. If your vendor is not present, create a new vendor line. For example. AudioVendor = 1002"AMD"

5. Add the following:


To test if you've done everything correctly, addOldDriver, save, and launch Halo. You should see a warning message. Hit exit.

5. Install HAC 2

EAX is environmental audio, things like echoing footsteps and reverberating bullets. If you are on XP you don't need to install this.

To install, download the latest version and extract into Halo CE's root folder.More information here.

14. Enable Antialiasing

Standard MSAA/SSAA does not work on Halo PC/CE and will result in an instant crash or a black screen.
NVIDIA users force FXAA in your control panel.
AMD users force MLAA in your control panel.

15. Online Performance

Set Halo CE's network settings according to your internet upload speed.In multiplayer servers, type ''/info'' into chat ingame to check if the server uses nolead. Nolead, part of SAPP server software, patches Halo CE's notorious netcode problem whereby players must apply ''shot leading'' by shooting his target slightly farther than one would think naturally, this worsens the higher your ping. Nolead fixes this and for new players especially, servers that uses nolead are highly preferable to servers that don't.

Take full advantage of Halo's glitches, especially backpack reloading
