Someone should send this as a guideline to Gabe:
"We have been planning to put together a proper pre-release of Doom for benchmarking purposes, but we have just been too busy with actual game completion. The executable and data that is being shown was effectively lifted at a random point in the development process, and shows some obvious issues with playback, but we believe it to be a fair and unbiased data point?We were not happy with the demo that Nvidia prepared, so we recorded a new one while they were here today. This is an important point -- while I'm sure Nvidia did extensive testing, and knew that their card was going to come out comfortably ahead with the demo they prepared, right now, they don't actually know if the demo that we recorded for them puts them in the best light. Rather nervy of them, actually."
