Quake Epsilon is a graphically enhanced build of shareware Quake 1 for Windows/Linux/Mac, which can be upgraded to the full version of Quake along with it's mission packs Scourge of Armagon and Dissolution of Eternity by copying the full-version.pak files into the correct folders. Quake II will not launch on Windows 10!! I recently got Quake II a week ago or two and when I tried to launch it, it crashed and said quake2.exe has stopped working.
Yamagi Quake II is an alternative client for id Softwares Quake II. Ourgoal is to provide the best Quake II experience possible, we strive topreserve the game play as it was back in 1997. Thus we aim mostly forbug fixes, stability and gentle enhancements were appropriate.
Features
Yamagi Quake II has a lot of unique features. The most notables onesare:
- A modern OpenGL 3.2 renderer, providing a greatly enhanced look andfeel. The original OpenGL 1.4 and even the Software renderers arestill supported. Both 3D accelerated renderers support anisotropicfiltering and multisampling anti aliasing.
- Full support for widescreen displays and arbitrary resolutions. TheHUD can be scaled to be readable on HiDPI displays.
- Support for surround sound, from stereo up to 7.1 channels and evenHRTF. The background music can be played from OGG/Vorbis files, a CDdrive is no longer necessary.
- A rewritten savegame system. Yamagi Quake II savegames are completelyreliable and backward compatible between releases.
- Highly precise timings. For example, on a flat panel display with a59.95 hertz refresh rate and vertical synchronisation (vsync) enabledYamagi Quake II is running at exactly 59.95 frames per second.
- In comparison with the original client over 1.500 bugs were fixed. TheYamagi Quake II client is very well tested and stable. The dedicatedserver is able to run for weeks without a single restart. Last but notleast the code is fully 64 bit clean and highly portable.
Yamagi Quake II supports the following platforms:
- FreeBSD
- Linux
- OpenBSD
- Windows
Some additional platforms are supported by the community. Yamagi QuakeII works on them, but there may be bugs. The Yamagi Quake II developersmay not be able to fix these bugs due to the lack of required hardwareor software:
- Haiku
- Mac OS
- NetBSD
- Solaris

Vulkan test builds
Denis ‘0lvin’ Pauk did a wonderfull job in porting the vkQuake2 Vulkanrenderer to Yamagi Quake II. It’ll likely part of the upcoming 8.00release. Until then feedback is needed to find the remaining problems.We’re publishing test builds at a regular intervall. Please reportproblems through Github:Bug tracker

Contribution and Bugreports
The development of Yamagi Quake II is hosted on Github. If you want toreport a bug or send some nice patches please open an issue or a pullrequest in the appropriate subproject. You can find our organizationat: github.com/yquake2

If you’re planing to work on a bigger feature, please do yourself afavor and ask if we’re interested before spending time onto it. Wedon’t merge every feature that’s submitted to us just because the codeis already there. Maintainability, integration with the existing codeand our general focus are of great concern, too.
If Quake Champions crashes, Quake Champions will not start, Quake Champions not installing, there are no controls in Quake Champions, no sound in game, errors happen in Quake Champions – we offer you the most common ways to solve these problems.
Be sure to update your graphics card drivers and other software
Before letting out all of your bad feelings toward development team, do not forget to go to the official website of your graphics card manufacturer and download the latest drivers. There are often specially prepared optimized drivers for specific game. You can also try to install a past versions of the driver if the problem is not solved by installing the current version. It is important to remember that only the final version of the video card driver must be loaded – try not to use the beta version, since they can have some terrible bugs.
Do not also forget that for good game operation you may need to install the latest version DirectX, which can be found and downloaded from official Microsoft website.
Quake Champions not starting
Many of the problems with games launching happen because of improper installation. Check, if there was any error during installation, try deleting the game and run the installer again, but before install don’t forget to disable antivirus – it may often mistakenly delete files during installation process. It is also important to remember that the path to the folder with a game should contain only Latin characters and numbers.
You also have to check whether there is enough space on the HDD for installation. You can also try to run the game as an administrator in compatibility mode with different versions of Windows.
Quake Champions crashes. Low FPS. Friezes. Hangs
Your first solution to this problem install new drivers for a video card. This action can drastically rise game FPS. Also, check the CPU and memory utilization in the Task Manager (opened by pressing CTRL + SHIFT + ESCAPE). If before starting the game you can see that some process consumes too many resources - turn off the program or simply remove this process from Task Manager.
Next, go to the graphics settings in the game. First – turn off anti-aliasing and try to lower the setting, responsible for post-processing. Many of them consume a lot of resources and switching them off will greatly enhance the performance, and not greatly affect the quality of the picture.
Quake Champions crashes to the desktop
If Quake Champions often crashes to the desktop, try to reduce quality of the graphics. It is possible that your PC just does not have enough performance and the game may not work correctly. Also, it is worth to check out for updates - most of today's games have the automatic patches installation system on startup if internet connection is available. Check to see whether this option is turned off in the settings and switch it on if necessary.
Black of black screen in the Quake Champions
The most common issue with black screen is a problem with your GPU. Check to see if your video card meets the minimum requirements and install the latest drivers. Sometimes a black screen is the result of a lack of CPU performance.
If everything is fine with your hardware and it satisfies the minimum requirements, try to switch to another window (ALT + TAB), and then return to the game screen.

Quake Champions is not installed. Installation hangs
First of all, check that you have enough space on the HDD for installation. Remember that to work properly installer requires the declared volume of space, plus 1-2 GB of additional free space on the system drive. In general, remember this rule – you must always have at least 2 gigabytes of free space on your system drive (usually it’s disk C) for temporary files. Otherwise, the games and the other software may not work correctly or even refuse to start.
Problems with the installation may also be due to the lack of an internet connection or it’s instability. Also, do not forget to stop the antivirus for the time game installation – sometimes it interferes with the correct file copy, or delete files by mistake, mistakenly believing they are viruses.
Saves not working in Quake Champions
By analogy with the previous solution, check for free space on HDD - both on where the game is installed, and the system drive. Often your saves are stored in a folder of documents, which is separate from the game itself.
Controls not working in Quake Champions
Quake 2 Crashes On Launch Today
Sometimes the controls in game do not work because of the simultaneous connection of multiple input devices. Try disabling gamepad, or, if for some reason, you have two connected keyboards or mouses, leave only one pair of devices. If your gamepad does not work, remember - the games usually officially support only native Xbox controllers. If your controller is defined in system differently - try using software that emulates the Xbox gamepad (eg, x360ce - step by step manual can be found here).
No sound in Quake Champions
Cached
Check if the sound works in other programs. Then check to see if the sound is turned off in the settings of the game, and whether there is correct audio playback device selected, which is connected your speakers or headset. After this check volumes in system mixer, it can also be turned off there.
