A test version of Quake III Arena created for compatibility testing with hardware vendors has been leaked. I contacted id about this, asking Director of Business Development Anna Kang what exactly it is that some have gotten their hands on, and she explained, saying "it is not a game, nor is it the test that will be out in about a month. Trying to play the IHV test will only lead to frustration." Here is the full quote about the leaked test:

A version of the IHV (independent hardware vendor) test has been leaked . The leaked version is used for the sole purpose of internal testing and contains no real levels. It serves no purpose other than for hardware vendors to test and optimize features such as multitexture and compiled vertex array implementation. It contains no playable maps. Some maps are specific for testing oversixed textures, extreme texture aspect ratios, and high polygon outputs (much higher than normal maps). We hope the public is aware that this leaked test is useless to them and illegal to have in their possession. This material was given under NDA and its sole purpose for distribution was for hardware vendors to test out various features. We're flattered that so many people are interested in getting their hands on the game, but what is out now is not a game, nor is it the test that will be out in about a month. Trying to play the IHV test will only lead to frustration.

I will not be posting links to "reviews" or links to sites that choose to post screenshots.
