RuneTek

RuneTek is the game engine used for RuneScape. RuneTek 5 is the current version of the engine which replaced RuneTek 4 on 2 September 2009. RuneTek 5 combines Standard Detail (SD) and High Detail (HD) modes. The updated SD in RuneTek 5 includes fullscreen and resizeable window modes, distance fogging and sky colour, ground/path blending and smoothing, and underwater visibility. The updated HD is yet to include further shadowing, sky boxes, while it already includes particle effects.

Development
Andrew Gower, Mod Chris E, and four other Jagex staff have recently finished RuneTek 5. It is unknown what they are working on at the moment.

In a developers' blog, Mod Chris E says that these improvements have been inspired from another Jagex product called MechScape, which has been renamed and reworked into an entirely new game titled Stellar Dawn.

It has been stated in a Q&A with Andrew Gower on 3 September 2009 that this update has made RuneScape that much closer to becoming a console game.

On the 22 December 2010, Jagex released a new trailer for RuneScape, showing a whole new level of graphics. Later, on RuneScape's Swedish Facebook, Mod Valkyrie posted about the new trailer and it was confirmed that the trailer was made using a new game engine that is currently being worked on.

Later, in the comments, in the same post, Mod Valkyrie aswered a question stating this:

History
* : RuneScape Classic still can be played, therefore it's also possible to say that this RuneTek is used in 2000-present

Trivia

 * On the RuneTek 5 images, one can see a blurred out spot which is the Objective system arrow. This image was released before the Objective system update. The text in the chatbox reads: "A starting arrow has been added to your world map", indicative of the existence of the Objective system during the release of this blog.
 * The updated log out button was also visible in these screenshots before Runetek 5's release.
