Bane of Gamestop employees, beloved of 4chan.

Muh gaymes is the primary excuse for people not joining the GNU/Linux master race. However, our lord and savior Gaben wants you to think otherwise.

Platforms & Technologies

Microsoft Windows

Microsoft Windows is currently the premier PC gaming platform. This is due to several factors; including pre-installation agreements with major PC vendors, relatively poor driver support for other platforms by hardware manufacturers, and the favoured position enjoyed by Microsoft's proprietary DirectX technologies in the modern games industry.

DOSBox

DOSBox is a free and open source MS-DOS emulator designed with classic games in mind. Binaries are available for every major modern operating system. To those without MS-DOS experience, DOSBox might seem a bit confusing. For a list of supported and assistance in getting them working, refer to the DOSBox Compatibility List and the DOSBox Forums.

The Wine Project

Wine is a free and open source compatibility layer that is capable of running many Windows programs without emulation under the following POSIX-compliant operating systems: Linux, Mac OS X, and BSD. For a list of supported games and instructions for getting them working with Wine, refer to the Wine Application Database.

DirectX

An API, mostly used as a library for creating muh gemes exclusively on the Windows platform.

OpenGL

Or Open Graphics Library is a multi-platform API developed by Khronos Group. Unlike DirectX which is a package of multiple libraries, OpenGL only deals with rendering of 2D and 3D graphics. And unlike DirectX you will never have to deal with Microsoft to use it.

Common Visual Effects

Anisotropic Filtering

Basically the further you are away from the camera textures tend to misalign so anisotropic filtering is used to align textures back. There is absolutely no reason not to max it by default in every video game since the performance impact is barely noticeable. It is still a big mystery to why every hardware benchmarking test from popular web sites and magazines include AF in the settings lists, but universe may never know the answer.

Anti-Aliasing

A common way to fix the problem of "jaggies" on outer edges of 3D models in video games. There are multiple AA methods that "fix" the problem in a different way, with a different effect on the performance.

Downsampling

While downsampling can not be compared to other AA methods, it is widely used by gamers and is by far superior way to fix the problem of jaggies in video games by running games at higher-than-native resulutions. 95% of all vidya does not have this feature but there is a way to force it via user made software and stock GPU control software. It will also render games at much better quality. But with high quality comes perfomance impact that is higher than any other AA method.

Bloom

Is an effect that gives certain glow to rendered image. Clearly a stylistic effect but for some reason it is included as an options in many many games.

Tessellation

Most people think that tesselation is all about giving detail to 3D models the closer you move game camera to them but in reality tesselation in video games is referes to two things - polygon streaming and actual tesselation. Tesselation is a technique to generate polygons in the space between existing polygons to increase detail of objects. Polygon streaming commonly paired with tesselation but can be used without it to stream existing high-poly mesh data into the model depending on the distance/angle from the camera to 3D model.
