HardOCP.com isn't done benchmarking Doom 3. Apparently they spent a good 65hours benchmarking Doom3 on an array of PC-setups with videocards ranging from the GF3/8500 to the latest cards. Working with Id, they chose the best area for a timedemo, and compiled a list of Doom3-configurations to give the best IQ for each system without degrading playability performance.

I'm not a huge fan of Kyle's work, but MAJOR props to him and Id for setting this up

The format of this will not be as traditional benchmarks that you guys are used to. This will the DOOM 3 [H]ardware Guide. We will be concentrating on best performance out of each setup and what to expect from overall system performance. Currently we will not be graphing more than one video card on any graph. It will not be a comparison. That said, we will certainly show you what was the highest playable IQ that each system would provide and we did this using REAL gameplay that covered half a level and runs about 5 minutes. We worked with id on picking the "right place" to do the run-through. That said, we did test on other levels to make sure our IQ calls were "right" and delivered playable performance. If anything, we tried to be on the conservative side of things and certainly some will find some better IQ settings that are playable for them.
