The X-ray Engine is a DirectX 8.1/9 Shader Model 3.0 graphics engine. Up to a million polygons can be on-screen at any one time. The engine features HDR rendering, parallax and normal mapping, soft shadows, motion blur, widescreen support, weather effects and day/night cycles. As with other engines that utilise deferred shading, the X-ray Engine does not support anti-aliasing with dynamic lighting enabled. However, a "fake" form of anti-aliasing can be enabled with the static lighting option; this format utilizes a technique to blur the image to give the false impression of anti-aliasing. The game takes place in a thirty square kilometer area, and both the outside and inside of this area is rendered to the same amount of detail. Some textures in the game were simply photographs of the walls in the developers' studio.

Quote:x-ray is a great engine and probably the most capable engine I have ever seen.
Sadly though it is hard on the proccesor and RAM.

This mod/addon/whatever will bring updated engine with multicore support and fixed freezes: Moddb.com
The developers got X-RAY source code...

A: Lost Alpha is based on a beta patch, called 1.0007. This was never released to the public, but we had the opportunity to get it, and fix it up. The engine is now totally upgraded, runs better than ever. This means, you don't need any SoC patches for LA, since now it became a standalone (but still free) game.

You sir, are a major douche. Judging from all the bad ratings you give to top notch games and engines, I'd say it's safe to say that you are not capable of modding anything but Id tech.

How old is SOC/CS/COP how many gamers have had and still have major issues with these games no matter the high or low their hardware specs. X-ray its a bag of broken unoptimized Object and always has been and always will be, get real and eat some H pie.
