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.

It's made out of the Darkplaces engine and many mods from members of the Quake One forums and elsewhere (these are listed in the readme for each pack) as well as my own work. If it were not for these people, this build would not exist, so consider thanking the authors directly. These builds are legal and do not contain pirated content. Just simple unzip-and-play stuff.

There are four graphics modes, which you can switch between via a batch file ('High' is the default):

  • Ultra - Recommended for the bleeding edge of current (~2011) computers. Recent cpu recommended. Reflecting surfaces, bump-mapping, environmental effects, multiple particle effects, better flames, high-polyon models, effected reflecting water, ultra quality texturing.
  • High - Recommended for most modern machines. For good machines with good graphics cards. Geforce 7800 or upwards, dual-core 3ghz & upwards recommended. Environmental effects, multiple particle effects, better flames, high-polyon models, effected reflecting water, ultra quality texturing.
  • Medium - For medium spec computers and laptops with reasonable onboard 3d chipsets. Transparent water, high quality texturing, graphical options optimised for performance, while still retaining the 'modern' feel of the quake epsilon build.
  • Low - Recommended for older laptops, graphics cards without shader support, and older machines in general. But it's also designed to be similar to the original quake as possible for those who want a nostalgia trip but with higher quality textures. Few/no shader effects, uses the QRP texture pack, which is less gritty and grimy but more like the original quake, and uses less memory.

Please note that it runs much faster on Windows, so that would be my platform of choice if you have the option.
I don't want to clutter this summary, so more details and all credits can be found in the readme for each pack and on the homepage (http://www.xpfree.org/epsilon).

Well that was exhausting.
I'll thank LordHavoc (author of darkplaces) plus my two testers for their help in wrestling out these bugs while various dependencies etc were discovered.
The main changes are the problem with textures not showing up or being low-resolution on some windows machines/linux distros, which is fixed now.
All known linux dependencies are now included and installed on first run.
There's also texture fixes for mission pack 3, and a bunch of other stuff. See patch for details.

Hello, you've done a great job creating this mod, but I have a problem.
I can only see half of the HUD bar and some of the icons are too big! Ex: numbers
Did you encounter this bug before?

No, that's pretty crazy!
I'm struggling to think what could cause that.
Have you tried different graphics resolutions to see if it fixes it?
Also try disabling FXAA/MLAA in your graphics cards settings and disabling antialiasing in darkplaces, might help-

Verifying the integrity of game cache did it.
The bottom right corner looks like it's cut out, but I'm glad the rest works.

So apart from having my eyes melt with such impressive visuals. I also having some performance issues :( (I am running 'Ultra" btw)

Even with an i5 4690K and R9 290, on "START.BSP" getting drops to somewhere around 20fps which doesn't make sense to me. Considering at other points my system easily gets 100+fps. I'm guessing its some particular effect that is slowing everything down.

Any ideas besides just switching down to "High" or "Medium" quality. I still get the massive frame drops on "high" quality as well.

Yup, "start" gives you a clear picture of how your system will behave at the most cosmetically-demanding sections of the game, visually-speaking. It's the smoke/etc effects, mainly.
Generally-speaking it's not something to worry about for the rest of the game.
The darkplaces engine is largely based around the cpu rather than the gpu for it's effects and isn't optimised for multi-core systems, unfortunately.
